Cooperatives have been part of the agricultural heritage of the Ruedinger family for three generations, and cooperatives remain an important part of my life today. In the 1940s, my grandfather helped found the Oshkosh Shipping Association, a cooperative formed to meet feed and seed needs of area farmers. As frozen semen became available, he began using artificial insemination service from a cooperative. My father began his cooperative career as a director for a local supply cooperative in the late 1960s. For nearly 30 years he was active locally and nationally in cooperative work. In the mid 1970s, my wife and I attended many cooperative leadership conferences. These conferences solidified my commitment to the cooperative way of doing business, offered insight, taught us the value of organization, business and governance structure, and offered a chance to work with other people in the industry — from dairy producers to management. Since cooperatives had become part of the Ruedinger way of doing business, when former director Ray Koepp asked if I had an interest, I decided to run for a 21st Century Genetics director position. After my election, I began to learn being a member of a cooperative is not just buying products and receiving service. Cooperatives are a complex system of smaller businesses rolled into one large business. They can be aggressive, yet conservative in their business approach. They offer diversity to the members they serve. The cooperative model also offers the ability for an organization to 4 © 2 0 0 6 C R I | Horizons change. I am proud to say I have helped to bring about some of the necessary governance changes for the membership of Genex/CRI. Since I became a director in 1989, growth through mergers and consolidations have offered opportunity within a mature industry. The 1993 formation of CRI was an industry milestone, creating new possibilities for Genex and for members. The consolidation was necessary to maintain the excellent quality of products and services members had grown to expect. The change to national membership has been very positive for our cooperative. With redistricting, we have 13 directors across the U.S. including two new board members. This adds a much needed diversity to the board of directors. There are distinct differences between producers in the West, Midwest and East. Now Genex can add value by drawing new ideas and suggestions for products and services from a vast population of livestock producers. As the cooperative has changed in the past, it will also change throughout the future. We will need to draw from our sister subsidiaries AgSource and Central Livestock. They offer a wide variety of programs which fit well into the Genex producer profitability model. We also need to continue to develop international markets — marketing not only semen, but our intellect. International markets add new dimension to the “outside the box” thinking management instills within Genex. This is evident in IndiaGen, our venture in India. This project could open the door to many more franchising opportunities. With knowledge and experience, your board of directors and management team offer the leadership skills necessary to meet the CRI mission. This driving force gives producers within the CRI family the ability to grow their businesses while maintaining a strong, viable cooperative. As former Genex president David Hileman wrote in a previous Horizons, “A member-controlled cooperative led by engaged and involved delegates, a strong board of directors and a skilled, dedicated management team all pulling together is a powerful business model.” I believe his statement to be true. By working together your cooperative has become a wellrespected leader in the industry. As I am proud to be the third generation in my family committed to the cooperative system of business, you too, should be proud of being a member of a strong cooperative with a bright future. Genex and CRI have outperformed expectations for the first half of 2006. All international markets remain strong and the International Division is above budget for revenue by $870,000. Genex service and semen within the U.S. continues to reflect our strong product offerings with a net savings of $2,777,000 as of June 30. One bright spot for Genex has been consistent increases in services. Producers have recognized the value of service teams to improve herd reproduction leading to increases of nearly 10 percent each of the last four years. This year is no exception with over 70,000 more services during the first half of the year compared to 2005. CRI Subsidiary News On July 5, AgSource Cooperative Services announced the acquisition of Harris Laboratories located in Lincoln, Neb. The laboratory has a strong presence in the regional ag market for soil testing, and an extensive clientele across the country in turf, tissue and specialty markets as well as a sizeable international business doing work for clients in 38 countries. The addition of Harris Labs to AgSource and CRI more than doubles the cooperative’s capacity in soil and agronomic testing. Central Livestock Association proudly announced a new relationship with an Internet auction called TEAM – The Electronic Auction Market. TEAM is a very successful Canadianbased on-line auction for livestock. TEAM provides excellent competitive marketing opportunities by bringing many buyers, sellers and cattle together through an electronic format. Individuals can register with TEAM as a bidder or an observer free of charge at www.teamauctionsales.com. Dates Set for Genex Fall Meetings The dates have been set for the Genex Fall Input Meetings.

Both of these reflect the impact of the sire and dam, respectively, in the birthing process. Average stillbirth percent among all birthings is eight percent and rises to 12 percent in first calvings. SCE and DCE represent about one-third of the value in CA$, and SSB and DSB account for two-thirds of the six percent. Each of the four birthing traits will be published; however, the CA$ will not be published as a stand-alone trait. The heritability of this group of traits is relatively low (less than .10); however, if no effort is made to select for them, progress will not be made except by accident. Overall, the value of this group of traits increases from 22 to 32 percent or nearly a third of the index. “50 Pounds of Flour” LNM$ 2006 also introduces the Calving Ability Dollar (CA$) index with a six percent weighting. It is related to PL and DPR as it measures the genetic birthing efficiency of a bull and his daughters. The index includes Sire Calving Ease (SCE) and Daughter Calving Ease (DCE) (first quantified in LNM$ 2003) and introduces and incorporates Sire Stillbirth (SSB) and Daughter Stillbirth (DSB) into USDA Economic Index (Year Introduced) Table 1 6 Ca Fat 23% lth Traits 41% Daughter Pregnancy Rate (DPR) has also been raised to nine percent of SCS -9% % Non-production trait values have been increased to reflect the value of cows that produce longer and are more reproductively efficient. Productive Life (PL) is now 17 percent of the value within the index. Additionally, PL has been revised to reflect the ability of today’s cows to produce high volumes of milk for longer periods of time. Its previous parameters capped a lactation at 305 days and a cow’s life at 84 months. The changes now credit a cow for more than a 305-day lactation, and also rewards her for staying productive past 84 months. Productive Life 17% 4 hs irt illb St What changed? And why?

The increases in PL, DPR and CA$ mean the production value is reduced to 46 percent in the index with equal values of protein and fat. However, Table 2 indicates the amount of production progress attainable using LNM$ 2006 as your selection index. And, frankly, we have been pretty successful at weighing the milk and increasing production. Why is it Important to Me? Obviously, sound management and husbandry practices are a key ingredient of any successful dairy, but if you like the idea of a more genetically efficient cow helping with the project let LNM$ 2006 be your guide. Table 2 reflects the progress genetically that can be made by using LNM$ 2006 as your primary breeding tool. I encourage you to note the progress that can be attained in PL, DPR and CA$. A Practical Approach “One purpose of a breeding program is to increase the frequency of those genes that contribute to a more profitable herd.” ~ Bennet Cassel Extension Dairy Scientist, Virginia Tech Use of LNM$ 2006 fulfills this statement for me. It is consistent with the Genex Mission Statement and provides dairy owners, whether large or small, with a current and practical approach to selecting service sires. It is research based and weighs the traits for bottom line profitability increasing the frequency of those genes that contribute to a more profitable herd. Table 2 PTA Trait Protein (lb.) Fat (lb.)

Each month, the latest breedings are analyzed using the best statistical analysis for non-return (to service) data. The outcome is individual bull fertility rankings. To date, these evaluations have only been used by our production division to optimize individual bull performance and, on occasion, to remove a bull from our active line-up due to poor fertility performance. Starting with the August sire summary, Genex will introduce GenCheck, a fertility evaluation on all bulls that have 300 or more services, but do not have an official Estimated Relative Conception Rate (ERCR) calculated by USDA. GenCheck, published in the Investment Guide following each sire summary, will provide Genex member/customers with reliable fertility rankings for more bulls based on the only true way to measure a bull’s fertility – through the cow. The GenCheck advantage will rank bulls in the following categories: Excellent + Very Good Average to Above Average - Average to Below Average L Recommend limited use based on limited data There are two outcomes for a bull ranked with an “L”: 1. With additional data his performance improves or 2. The bull is removed from the line-up. Three L Farm Ellenburg Depot, N.Y.

Fourth from the right, in the front row, is IndiaGen COO Dean Gilge. A Murrah Buffalo (below) poses with her newborn calf. India: An Industry Leader When you think of India, think of sheer numbers. Approximately one billion people live in India, a country one third the size of the U.S. The country is home to 100 million breedable dairy cows and buffaloes, compared to the U.S. with nine million. The average herd size is just under two cows per producer with average production close to 2,000 pounds/cow/year. Despite these low averages, India is the largest producer of milk in the world simply because of sheer numbers. Dairy Development The National Dairy Development Board (NDDB) of India deserves credit for strengthening the country’s dairy industry in the past 40 years. In short, NDDB’s goal was to replicate AMUL, a very successful milk producers’ cooperative. NDDB spearheaded teams to go into villages and help producers form farmer-owned cooperatives, much like our own U.S. cooperative systems with elected members serving on boards of directors. They titled these efforts “Operation Flood” as they strived to increase production to create a flood of milk, improve rural incomes and ensure fair prices for consumers. Today, NDDB is a cornerstone in India’s production agriculture industries. 8 © 2 0 0 6 C R I | Horizons IN THE NEWS At right, a proud dairy producer in Tirupati, India displays his two Holstein cross heifers. In India, many people use oxen (far right) or bulls to plow fields and pull carts. IndiaGen Technicians, including these in Mulaknoor, India, (center) drive motorcycles to their service calls. India is also home to many Jersey cows. Pictured (bottom right) are Jersey cross cows in Chittoor, India. IndiaGen Advancements Indian Immunologicals Ltd. (IIL), an NDDB organization dedicated to improving animal health, and CRI officially launched a joint venture in January 2005. The result was IndiaGen, the first artificial insemination (A.I.) company of its kind in India. Historically, A.I. has been available in India for many decades, but has always been subsidized to producers through a government agency or dairy cooperative union. IndiaGen is the first A.I. company to charge for service on a commercial basis to the producer. After the launch, the first group of A.I. technicians was selected and trained. They began breeding cows and buffalos in June 2005. By the end of the fiscal year, in March 2006, 120 IndiaGen technicians were performing A.I. services. Strategic goals call for an additional 380 A.I. technicians by the end of the 2007 fiscal year. In five years, the goal is to more than triple the number of IndiaGen technicians. In under two years’ time the IndiaGen field force will become one of the largest in the world, however these IndiaGen technicians operate in different conditions than U.S. technicians. While they use mobile phones to receive service calls from farmers, they use 150 cc motorcycles for transportation, carrying a three- liter liquid nitrogen tank on the side of their bike and A.I. kits in their backpack. Semen is procured through the top two bull stations in India, Sabarmati Ashram Gaushala (SAG) and the Animal Breeding Center (ABC). Breeds offered include Holstein, Jersey, Holstein cross, Jersey cross, Indigenous species and Murrah Buffalo. CRI semen will be available in the future as the USDA and India government develop import protocols. The relationship between CRI, NDDB and IndiaGen goes beyond semen sales. CRI has been hired on a consultant basis to increase IndiaGen knowledge of direct marketing, semen production and bull housing, progeny testing and information networking. Already, the system put in place through collaboration with CRI has helped IndiaGen technicians increase conception rates by nearly 20 percent to reach rates of 56 percent. A New Role with Genex/CRI For 23 years, I have been employed by CRI, most recently serving as an Area Sales Manager in central Wisconsin. In 2006, I became the first CRI employee to live outside of the U.S. and Canada, as my wife Jayne and I moved to the IIL campus in Hyderabad, India. My main responsibility as Chief Operating Officer at IndiaGen is to help establish A.I. centers throughout India. I focus on training technicians and managers, establishing delivery routes for semen and supplies, setting goals to meet budget, promoting products, and marketing the IndiaGen brand through village meetings, DVDs, radio and other media. My job has been exciting, though not without challenges such as language barriers. Some English is spoken, though Hindi is the national language. Also, each state within India has its own common language, which makes developing promotional material a difficult task. Traveling within the country has been an obstacle, too. Back home, 60 miles meant an hour or less drive. In India, 60 miles can take up to three hours on narrow roads shared with bicycles, cows, goats, dogs, motorcycles, bullock carts, elephants, camels, buses and large trucks. Working to overcome these and other challenges has made me enthusiastic about CRI and IndiaGen’s future together. Horizons | ©2006 CRI 8 HERD MANAGEMENT Improving Fertility and Increasing Conception Rates The dictionary defines fertility as “the state of being fertile, especially the ability to produce young.” Conception is “the actual formation of a viable zygote by the union of the male sperm and female ovum.” Together, they result in replacement animals and milk production - both of which affect on-farm profitability. To improve fertility and increase conception rates, consider Daughter Pregnancy Rate (DPR) and Estimated Relative Conception Rate (ERCR) respectively. Though they are very different from each other, both can positively affect reproductive programs if used correctly. | DPR | Q Definition: DPR measures the fertility of a sire’s daughters. It is the ability of daughters of a particular sire to become pregnant relative to a herd’s 21-day pregnancy rate. It is expressed as a percent, and each +1 percent DPR equals four fewer days open. Conversely, each -1 percent equals four more days open, relative to the herd average. Q Example: 1HO5045 LYNCH has a +1.9 DPR. If your herd’s 21-day pregnancy rate is 20 percent, your LYNCH daughters would be expected to have an average 21-day pregnancy rate of 21.9 percent. Likewise, if your herd averages 153 days open, you can expect your LYNCH daughters to average 145 days open and have a week shrten calving interval. Also, this trait (whether positive or negative) is inherited from generation to generation. Top Five Genex Holstein sires by DPR with LNM$ Sire DPR Rel.

It is the difference in conception rate of a sire compared to other A.I. sires used in the same herd. Each positive ERCR point indicates expected conception rate for that sire to be one percent higher compared to “average” service sires used in the same herd. Conversely, each negative ERCR point indicates expected conception rate for that sire to be one percent lower than “average” service sires used in the same herd. Q Example: 1HO6833 TRES has an ERCR of +3. Therefore, if the average conception rate of the average A.I. service sire used in your herd is 20 percent, then you would expect the average conception rate for TRES to be 23 percent within your herd.

However, the importance of DPR to improve fertility over the long term has been stressed by an increase in the percent weighting within the new 2006 Lifetime Net Merit $ (LNM$) index. DPR now makes up nine percent of the index. Q Strategic Use of ERCR: The benefit of a positive ERCR is recognized in the short term. While the use of positive ERCR sires can improve the probability of a bull to produce a pregnancy when a cow is bred, it has basically no genetic component (less than one percent) to increase fertility in future generations. It is recommended to incorporate DPR into your sire selection criteria by selecting sires according to LNM$. The index formula provides proper balance by recognizing the influence of improved fertility without overemphasis and sacrificing improvement in other areas. Through LNM$, you can select for the complete cow that performs well in all areas. Primary selection emphasis for A.I. service sires should focus on bulls with high LNM$ to increase overall profitability. ERCR should be used as a secondary selection tool when choosing sires to incorporate into a breeding program. Choosing high LNM$ sires with positive ERCRs will help increase conception rates while still breeding for the complete cow that performs well in all areas. DPR is a science-based evaluation that can provide increased reproductive efficiency in succeeding generations. ERCR is anecdotally evidenced. It can be used as a management tool to increase pregnancies, but has only a small bearing on future generation’s fertility. 10 © 2 0 0 6 C R I | Horizons HERD MANAGEMENT Improving Cow Pregnancy Success During By Pete Hansen Professor of Dairy Science, University of Florida Heat Stress: Not Just for Southerners Look at the lactating dairy cow as a factory that takes in fuel (feedstuffs) and burns it to produce milk. Not all the energy in feed is transformed into milk — much is converted to heat. To maintain a normal body temperature, the cow must lose that heat to the environment. The more milk she produces, the more heat she has to lose. High humidity and intense solar radiation compound the heat loss problem. When the cow can no longer regulate her body temperature, feed intake declines, milk yield reduces and reproduction is compromised. Due to increased milk yields, heat stress is no longer a problem only in the south. With air temperatures as low as 80 F causing elevated body temperature in high producing cows, cows throughout most of the U.S. and Canada suffer effects of heat stress sufficient to cause reduced milk yield and reproduction. Reduction in Detection of Estrus, Fertility Just like humans, a heat-stressed cow minimizes physical activity. Thus, symptoms of estrus become less pronounced. Production of estrogen, the hormone that causes estrus behavior, can also be reduced by heat stress. In a Florida study, the estimated percent of estrous periods missed by herdsmen increased from about 40 percent in cool months to as high as 75-80 percent during hot months. Even if estrus is detected, it is not likely a cow with elevated body temperature due to heat stress will get pregnant following insemination. 12 © 2 0 0 6 C R I | Horizons The cow undergoes physiological changes in response to heat stress leading to damage of the egg and, following fertilization, the embryo. The magnitude of reduction in fertility caused by heat stress can be severe. In south Florida, summer conception rates less than 10 percent are common. Is Heat Stress Affecting Your Operation? Analysis of herd records for seasonal variation in fertility will indicate whether heat stress is a problem. Another way to assess the degree of heat stress is to measure rectal temperature in selected cows — the higher the body temperature, the greater the reduction in fertility that can be expected. The cow’s normal body temperature is about 101.3 F. An increase in body temperature of about 0.9 F has been estimated to cause a decline in conception rate of 12.8 percent. One can consider a cow with a rectal temperature of 102.2 F or higher in the afternoon is likely to be heat stressed (if she does not have mastitis or is otherwise sick). An increase in a cow’s body temperature of about 0.9 F has been estimated to cause a decline in conception rate of 12.8 percent. Cooling Cows One way to minimize effects of heat stress is to provide housing that alleviates heat stress. This can be expensive. The degree to which housing should be modified to reduce heat stress will depend upon geographical location and extent of heat stress. Search the Internet for details on specific housing systems. Methods to Relieve Heat Stress for Florida Dairies http://edis.ifas.ufl.edu/AE022 Cooling Ponds for Dairy Cattle http://edis.ifas.ufl.edu/DS172 Interactive Tunnel Ventilation Program http://www.prodairyfacilities. cornell.edu/Intro.htm The simplest structures for providing cooling are shade structures. These can be inexpensive structures based on use of shade cloth or more permanent structures. By itself, shade is not very effective at preventing elevated body temperature in lactating cows if heat stress is moderate or severe. A common and fairly effective system for cooling cows is freestall or loose housing with sprinklers and fans. In tunnel ventilation barns, air is pulled through a low-ridged barn via a bank of exhaust fans at one end. A tunnel ventilation barn has a low roof and enclosed sides. Including foggers or misters can promote evaporative cooling as air moves through the barn. The tunnel barn is an expensive facility, with little documented evidence of effectiveness. Available information, based on producer experience and some experimental studies, provides optimism tunnel ventilation can be an effective method to keep cows cool. Heat-stressed cows willingly immerse themselves in water, so cooling ponds are sometimes used to allow cows to exhibit this behavior. Cooling ponds rapidly drop a cow’s body temperature. These artificiallyconstructed ponds are often built with constant movement of fresh water into the pond. There is little evidence the incidence of mastitis increases for cows in ponds, but be aware bacterial counts in the water can be high and the potential for problems exists. HERD MANAGEMENT Summer’s Heat Management Strategies to Improve Reproduction Cooling by itself is not sufficient to prevent effects of heat stress on reproduction. Even in well-managed herds with extensive cooling systems, reproductive function can suffer in the summer. Incorporating estrus detection aids in an estrus detection program can improve reproductive performance driving heat stress. In a Florida study, the percentage of cows detected in estrus after estrous synchronization using prostaglandin was 26 percent based on visual detection only versus 43 percent based on visual detection combined with tail chalk. Timed artificial insemination (A.I.) programs such as Ovsynch® can completely eliminate effects of heat stress on estrus detection because cows are inseminated at a fixed time regardless of estrus. In a Florida herd with a voluntary wait period of 70 days, the percentage of cows pregnant by 90 days postpartum was 16.6 percent for cows in which first insemination was via timed A.I. using Ovsynch versus 9.8 percent for cows inseminated at visual estrus detection only. Benefits of timed A.I. programs during heat stress accrue because more cows are bred — timed A.I. does not reverse the effects of heat stress on conception rate. If fertility following timed A.I. is very low because of heat stress, benefits of timed A.I. might not be realized. Unfortunately, there are no specific treatments to improve fertility of cows bred by A.I. Heat stress results in the formation of a defective egg whose damage cannot be reversed. Even if the egg escapes heat stress and gets fertilized, the embryo is susceptible to damage caused by Figure 1. Housing techniques used to cool cows. Shown clockwise from the upper left are cows under shade cloth, a barn with tunnel ventilation, cows enjoying a cooling pond, and a free-stall barn equipped with fans and sprinklers. elevated body temperature until day 3 to 5 of pregnancy. With embryo transfer, effects of heat stress on the egg are avoided because the embryos transferred are those derived from eggs with sufficient quality to give rise to transferable embryos. Embryos can also be produced during cool months of the year, when the egg is not susceptible to heat damage, and frozen for transfer in the summer. Effects of heat stress on the embryo are avoided because embryos are transferred at day 7 or 8 of pregnancy. Results from two experiments demonstrating improved pregnancy rates in heat-stressed cows using embryo transfer are shown in Figure 2. The main limitation to embryo transfer is cost. Embryos produced by superovulation can be expensive. Those produced by in vitro fertilization are less expensive.

Services per conception for pregnant cows and all cows. 6.0 5.0 4.0 Services/Cow Services/Pregnancy Reproductive Improvements Take Time Because many reproductive parameters have statistical momentum, typically there is a lag in time before improvements can be seen once a new management program has been implemented. In our case, at the U. of I., the average days to first service traditionally hovered around 80 days prior to implementing the program described previously. Within a few Oct-03 Dec-03 Jun-03 Aug-03 Apr-03 Jan-03 Sep-02 Nov-02 Jul-02 Mar-02 May-02 Jan-02 Nov-01 2.0 Sep-01 3.0 May-01 In September 2002, the University of Illinois (U. of I.) dairy implemented a timed breeding program. Fresh cows were started on a Presynch/Co-Synch program and open cows were started on just the Co-Synch program. The VWP was moved from 45 to 60 days, and the program was designed to have all fresh cows receive their first service between 61 and 67 days in milk. Cows not conceiving to the first service were re-bred on observed signs of heat within 18 days after initial A.I. Weekly herd checks were performed and the first pregnancy check was done at day 33 post breeding. Cows found open by rectal palpation were restarted on the Co-Synch program. The success of the program can be seen in Figures 1 and 2. 175 Feb-01 Traditionally, heat detection has been the means by which cows are presented for A.I. service. You would have to follow each cow around for 24 hours per day for 2124 days to detect each and every heat. Even then, you could not expect to achieve 100 percent heat detection due to variables involved with expression of estrous. With the use of reproductive schemes that not only synchronize heats, but also synchronize ovulation, we can achieve nearly 100 percent service rates within 21 days of the VWP. 200 Feb-01 MAXIMIZING FERTILITY Strong Repro Results Well Worth the Wait months a decrease was seen as more and more fresh cows became enrolled in the program (Figure 1). By November 2004, the average days to first service was 66 days and was consistent across all lactation groups. Initially, the average days open decreased to a historic low of 135 days, but climbed significantly as many cows late in lactation became pregnant through the new reproductive program. In the second year of the program, the average days open services were by Co-Synch at 61-81 DIM. At that first Co-Synch service, 31 percent became pregnant. Heat detection was required to present cows for service at the second cycle (82-102 DIM). Only 19 percent of eligible cows are detected in estrous and only 3 percent of cows eligible for pregnancy during that time frame became pregnant. During the third cycle (103-123 DIM) after the VWP, 77 percent of cows were presented for service due to a second Co-Synch program. Pregnancy rates for this cycle were 30 percent. The following cycle (124-144 DIM) required heat detection for cows to be presented for service. Again, the service rate was only 33 percent and the subsequent pregnancy rate of eligible cows was only seven percent. Services per conception for pregnant cows and all cows can be seen in Figure 2. In the past, services per cow was never below four and often exceeded four services, while services per pregnancy hovered around 2.5. Services per conception peaked at 5.5 for all cows and 3.3 for pregnant cows one year after the program was initiated. Concern was voiced regarding the amount of semen required to maintain the program. However, much of the increase in semen units used was required to catch cows up in the program. In year two, as the whole herd entered the program after calving, services per conception began to fall. As of November 2004, services per cow and services per pregnancy were at historic lows, 3.4 and 2.3, respectively. Improve Heat Detection to Improve Repro Program Improvements in heat detection, especially 18-24 days after the Co-Synch breeding would take this reproductive program to the next level. Traditionally, suggestions for improvements in heat detection have emphasized more frequent observations of cows. While this The nine-month, 21-day pregnancy rate also improved over the two years. Table 1 shows the 21-day pregnancy rate by Days in Milk (DIM) at service as of November 2004. Almost all (94 percent) of first Table 1 Nine-month, 21-day Pregnancy Rate Summary by DIM practice will, no doubt, increase the number of cows presented for service, all efforts at improving heat detection cannot be placed on more observations alone. Environment, nutrition, physiology, as well as the human labor force all play a role in enhanced heat detection efficiency. Environmental factors that can reduce heat detection efficiency include slippery surfaces, time spent on concrete, time in holding pens, poor freestall design and use, overcrowding and subsequent lameness. Nutritional factors include energy balance, mineral status, feeding management that may lead to rumen acidosis and lameness. Animal factors may include socialization and grouping strategies, body condition, other diseases and physiological problems. Fixing these problems will help the workforce at the dairy by allowing cows to naturally express estrous behavior. Then, enhancements in heat detection efficiency depends on the labor force. Providing visible cow identification, use of heat detection aids (tail chalk, heat patches, pedometers, etc.) and making observations a routine chore can then be accomplished.

HERD MANAGEMENT Boost Your Repro Program with Increased Compliance by Roy Wilson Technology Development Manager Genex Cooperative, Inc. Is compliance the largest culprit of reproductive problems on your dairy farm? Today’s dairy industry professionals have adopted many new technologies and techniques, however, no new advancement except for artificial insemination (A.I.), may be as widespread and accepted as synchronization. Nevertheless, this “tool” is only as good as the operator. Think about Ovsynch®: Science has proven if a cow receives a GnRH shot on day one, PGF2 on day seven and GnRH on day nine the majority of cows will ovulate. Keep in mind, science did not prove if a cow receives a GnRH shot on day one, PGF2 on day eight and GnRH on day nine that the cow will ovulate. Why is Compliance a Must? Reproduction impacts your bottom line. Following scientifically-proven synchronization protocols correctly is your best bet for positively impacting your bottom line. Look at examples one and two, to the right. These examples demonstrate the potential devastation incompliance can have on a reproductive program. However, knowing your compliance rate may not be as simple as seeing all the cows crossed off the list. It may actually be one of the most difficult issues for a farm to address. Here are some tips to discover your compliance rate and to help promote compliance: 1 First and foremost, take time to educate the employee(s) who administer the shots and breed the cows. If he/she understands why each shot is important and why 18 © 2 0 0 6 C R I | Horizons Example 1: Ovsynch Farm A demonstrates average protocol compliance giving the correct cow the correct drug at the correct time with 80 percent accuracy. At 80 percent accuracy for each of three shots only 51 percent of the animals enrolled in the program are being synchronized correctly! Farm B demonstrates good protocol compliance with 95 percent accuracy per shot. Nevertheless, even at 95 percent accuracy for each of three shots, at least 14 percent of the cows will have to be re-synchronized. GnRH PGF2 Farm A 80% Farm B 95% 80% 95% GnRH Synchronized Correctly 80% = 51% 95% = 86% Example 2: Presynch Farm A: Using a protocol with more shots, the average compliance herd (at 80 percent compliance per shot) only manages to have about one third of the cows correctly respond to the protocol! Farm B: This farm has very good compliance and still only manages to have just over 75 percent of the cows set up correctly! Farm A Farm B timing is crucial, there will be more buy-in and the employee will take ownership in the program. 2 Increase compliance by working with the individual in charge of following the protocol. When an employee comes back with cows not crossed off, do not reprimand him/her. Instead, thank him/her for notifying you and assist in finding the animals. You may find the cows were culled and not yet entered in the computer, or they were possibly moved to a different pen. 3 If you are uncertain about compliance, create a phantom cow on the list. If the list comes back PGF2 80% 95% PGF2 80% 95% GnRH PGF2 GnRH Synchronized Correctly 80% 95% 80% 95% 80% 95% = 33% = 77% with the cow crossed off, you know compliance is a problem that may need to be addressed. 4 Calculate how much GnRH, CIDRs or PGF2 you should go through in a month according to the protocols and recommended dosage level. Then watch the inventory for fluctuations. For tips on how to motivate employees also read Jim Henion’s article on pages 26-27. Remember reproduction management is a challenge by itself, but incompliance can destroy your results even before the protocol has an opportunity to prove successful.

Our pregnancy rate, or successful embryo transfer rate, improved 7.6 percent simply by implementing CIDR use,” said Jennifer Patterson, Embryo Programs Manager. on detected heat. For heifers, administer CIDRs on day zero, inject prostaglandin on day six and remove the CIDR on day seven. Then, heat detect on days eight to 11 and breed on detected heat. Besides improved pregnancy rates, inserting CIDRs into heifers at the GENESIS MOET facility allowed for group embryo transferring and calving synchrony making labor efficiency possible. Useful Tips and Tricks How Does It Work? Incorporating CIDRs into the reproductive program at the Genex GENESIS MOET (Multiple Ovulation Embryo Transfer) facility near Shawano, Wis., led to significantly improved reproductive results in 2005. “In 2004 we used the Co-Synch protocol to synchronize recipient heifers so we could implant embryos. For 2005, I decided to make a change to the program. Using CIDRs, we were able to improve our overall pregnancy rate CIDRs induce estrus regardless of the stage of cycle when inserted. After inserted, they release progesterone continuously. When removed, the drop in progesterone triggers estrus and ovulation. Pfizer Animal Health recommends the FAST BACKSM Breeding Program to resynchronize lactating dairy cows that were inseminated, but did not conceive. In this method, the CIDR is administered 14 days after the first artificial insemination and removed seven days later. Cows should be monitored for heat for the next four days and bred • Wear protective gloves when handling EAZI-BREED CIDRs. • Make sure the tail of the CIDR insert is on the underside of the applicator, curling downward, to ensure the tail will be hidden from curious pen mates. You may also want to clip the tail of the insert so only 2.5 inches protrude from the vulva. • “If you pull the CIDR out on day seven, you should be okay. If you pull the CIDR out earlier, the follicle may be premature. If you pull it out later, it could be cystic,” says Jennifer.

At any one time, they have between 100 and 150 Kamar detectors on cows and heifers in freestalls with open lots. identification, in the case that it would fall off. Q Wear milking gloves when applying the patch to keep glue off of your hands. If you do get glue on your hands, WD-40 works well to remove it. Applying the Product 1) Apply glue to tailhead. How Does It Work? Kamar Heatmount Detectors are a pressure-sensitive device with a built-in timing mechanism designed to be activated by standing heat activity. The detector is glued to the tailhead (glue is provided) and pressure from the brisket of a mounting animal requires approximately three seconds to turn the detector from white to red. The timing mechanism helps assure activation from true standing heat, rather than false mounting activity. A fully triggered Kamar along with the associated physical signs of a red, puffy vulva and clear mucous discharge is an excellent indication a cow is in heat. 2) Apply glue to back of Kamar. 3) Press Kamar firmly to tailhead. Q “During the spring and fall when the animals are shedding hair, we brush the lose hair off the tailheads before we put the Kamars on. Then they stick to the animals really well.” —David 20 © 2 0 0 6 C R I | Horizons No Need for Glue George Dairy Cattle Eugene George Baldwin, Kan. + “When I breed my cattle, I use Estrus Alerts,” says Scott Mesik, a Genex Area Sales Representative in Kansas. “I’ve been using them since the product was released and I’ve recommended them to Genex member/customers in the area.” Eugene George, a dairyman in Baldwin, Kan., took Scott’s advice and began using Estrus Alerts on his dairy over a year and a half ago. “The main reason I use Estrus Alerts is because you don’t need glue. They stick very well. If the animals are shedding in the early spring a couple patches might fall off, but during the summer and fall months I don’t have any problems at all.” Since Eugene’s 140 milking cows are on pasture most of the day, he lets Estrus Alerts do the heat detecting. Each morning and night, he quickly and easily checks the Estrus Alerts and breeds the cows accordingly. How Does It Work? Useful Tips and Tricks Q Write the animal identification and date on the Kamar for easy Estrus Alerts®: Apply patch before standing heat or at the start of a synchronization protocol. As cows are mounted, the silver surface rubs off to reveal a bright signal layer. True standing heat is detected after several mounts when most of the bright signal layer – fluorescent orange, green, pink or yellow – is displayed. Useful Tips and Tricks Q Do not shave the animal’s tailhead before applying the patch. 4) With pressure from mounting the Kamar will turn from white to red. Q Try to remove dirt and loose hair from the tailhead before application. Q “For me, they often stay on better when applied across the hips.” —Scott Q “One local producer uses different color patches for different breedings. A week after a cow is bred, he puts on an Estrus Alert patch. For first breedings he uses either orange or pink patches, and for subsequent breedings uses green or red.” –Scott Applying the Product 1) Warm patches in your pocket. 2) Remove backing and press firmly to tailhead. DETAIL™ Tail Paint: A More Durable Product Genex Representatives Wisconsin Vermont + + Bryan Chicoine, a Genex Breeding Program Specialist (BPS) within the “Cowpokes” breeding team in western Vermont, describes cows marked with DETAIL Tail Paint as his walking chalkboards. Bryan recommends DETAIL paint because it “is highly visible and has great staying power. It stays on cows longer than other materials, like chalk, so less maintenance is needed.” Daily, the Cowpokes team applies DETAIL paint, or walks pens to detect heats for cows with DETAIL, on eight dairies totaling roughly 1,700 animals. DETAIL is also a choice heat detection aid in northeast Wisconsin. “I use quite a bit of DETAIL paint, mainly for heat detection purposes,” explained Dave Hennes, a BPS in northeast Wisconsin. “I choose to use it largely because cows will not lick DETAIL like they will chalk. It also stays on longer and is more durable.” “Members and customers in my area also use DETAIL for marking fresh cows or cows for pregnancy checks. Some mark cows for herd checks the day before to save time,” he added. Q “We use one color per pen to help keep cow groups from getting mixed. It helps the employees keep the cows in the correct group.” —Dave Q “I always use DETAIL to put the breeding date on the cow. That way, when I go back the next day and see she was ridden again, I automatically know to use the same bull to breed her.” -Dave Q “The main trick is to work it into the hair. I always try to make the hairs stick up - liked a spiked hair cut would look.” –Dave Q “When breeding cows or using heat detection aids, cows need to be manageable. Having restraints, like headlocks or a palpation rail, allows us to to work with the cows to get them bred.” —Bryan Applying the Product 1) Shake the bottle. 2) Apply strip to tailhead. How Does It Work? 3) Mounting action removes silver cover layer revealing bright base. DETAIL Tail Paint is applied in a 2 x 6-inch strip along a cow’s tailhead. The water-based, non-toxic paint rubs off by mounting action. Useful Tips and Tricks Q Rinse the brush applicator out between uses for better paint flow. 3) Or, mark cows.

New research on the implementation of early pregnancy diagnosis using transrectal ultrasound in a synchronization and resynchronization system confirms this notion. Our research, below, illustrates on-farm considerations for early nonpregnancy diagnosis. Presynch GROUP A New reproductive management technologies hold the key to maximizing reproductive efficiency on dairy farms. However, reproductive protocols that allow for synchronization of estrus, and identification and resynchronization of nonpregnant cows must be practical to implement within the day-to-day operation of a dairy. Otherwise, the protocol will fail due to lack of compliance. This is especially true for larger farms that must schedule and administer artificial inseminations, hormone injections and pregnancy tests for a large number of animals on a daily or weekly basis.

For group B, pregnancy diagnosis via ultrasound and the first GnRH shot of the resynchronization protocol were both conducted on day 26. In group C, pregnancy diagnosis and resynchronization were conducted on day 33 following first TAI. Method of Discovery Research included the use of two technologies for reproductive management – synchronization protocols (Ovsynch® and Presynch), and transrectal ultrasound for early identification of nonpregnant cows. Ultrasound, PGF2 to open cows GnRH + TAI Examining the Results At the first pregnancy exam, the overall pregnancy rate for Presynch TAI was 40 percent (Table 1). The pregnancy rate was greater in groups A and B since pregnancy status was determined at 26 days after insemination. Group C, ultrasounded 33 days after insemination, had a significantly lower pregnancy rate. The lower pregnancy rate for group C is likely due to the longer time period in which embryonic 26 PGF2 GnRH + TAI 33 35 Ultrasound, GnRH to PGF2 open cows 33 GnRH + TAI 40 42 mortality could occur (33 days from TAI to pregnancy exam, instead of 26 days). Pregnancy status was reassessed for all groups at 68 days after Presynch TAI. This time, the overall pregnancy rate was 31 percent and did not significantly differ among groups (Table 1). This shows the differences in pregnancy rates between the first and second pregnancy exams were due to embryonic loss over time rather than to treatment differences (ultrasounding at 26 days versus 33 days had no effect on pregnancy). Overall pregnancy rate for resynchronization (Ovsynch TAI) was 32 percent, and was greater for cows in groups B and C than for group A (bottom row of Table 1). The data suggests waiting to diagnose pregnancies and to begin resynchronization until day 33 will result in significantly higher pregnancy rates when rebreeding nonpregnant cows because of the high rate of embryonic death occurring in cows diagnosed pregnant at 26 versus 33 days post TAI.

Challenges for Early Pregnancy Diagnosis Table 1 illustrates the limitations of incorporating early pregnancy diagnosis into a reproductive management program. First, the system with the most aggressive early nonpregnancy diagnosis and resynchronization schedule (group A) was not a viable management strategy based on poor fertility after resynchronization (23 percent pregnancy rate). This was probably due to follicular and luteal stages at the time the post-breeding resynchronization protocol was initiated.

EMPLOYEE DEVELOPMENT Motivation — What is it? Where does it come from? by Jim Henion Director of Consulting Services Cooperative Resources International Dr. Edward Deci, Department of Clinical and Social Sciences at the University of Rochester, tells us, “Motivation means you have energy to behave in a certain way and that you have a sense of direction for that behavior.” One of the common questions expressed by farm managers is this: “How can I motivate the people who work for me to follow our protocols, to work as a team, to come to work on time, etc.? Dr. Deci answers this way: “The question ‘How can I motivate another person,’ assumes an individual’s motivation comes from outside of them and is determined by someone else. Motivation, however, does not come from another person.” Employee Development Series The This article is part of a series geared to provide helpful hints for owners and managers working with others on the dairy. 1 Changing Roles and Responsibilities of Farm Managers (May 2005 Horizons) 2 Leading and Influencing Others (Aug. 2005 Horizons) 3 Improving Teamwork and Cooperation (Nov. 2005 Horizons) 4 Locating and Hiring Farm Employees (Feb. 2006 Horizons) 5 Orientation and Training of Employees (May 2006 Horizons) # 6 Motivation — What is it?

In future HORIZONS: 7 Improving Employee Performance 8 Understanding Cultural Differences 26 © 2 0 0 6 C R I | Horizons He continues, “Intrinsic, or selfmotivation is all about doing something because it’s really interesting and compelling to you. You take action because you feel a sense of satisfaction as you engage in the activity. “We think the environment an employee is working in is very important not because it motivates him or her, but because it creates the conditions that allow them to motivate themselves.” Dr. Bernie Erven, Ohio State professor emeritus and human resource specialist provides further insight. He tells us, “Motivation is about needs. If you can just figure out what each employee needs, satisfy those needs through their jobs and then reward them, employees will be self-motivated. It is an individual’s needs that drive their motivation.” What do employees want from their work? To get a handle on these ideas about creating an environment where employees will be self-motivated, let’s take a look at what employees want or expect when they accept a job to work on your farm. In his book, “First Things First,” author Steven R. Covey offers a plan for a rewarding life (and job). He suggests every person has a basic desire ‘to live, to love, to learn and to leave a legacy.’ Tom Thompson, Stotz Diary, Buckeye, Ariz., calls these ‘the four L’s.’ He says, “By ‘LIVING,’ we want our employees to have a safe work environment. We want them to come to work, do their jobs and feel safe. “In the context of ‘LOVE,’ we want our employees to feel wanted and part of a winning team they can be proud of. “We provide many educational opportunities which fulfill employees’ need to ‘LEARN.’ Whether it’s helping our Hispanic employees to learn English on a weekly basis or having someone come out and teach them how to do their jobs better, we believe in constant education. “And finally, for the ‘LEGACY’ part, I think all of us would like to go through life feeling we are making an impact. When we achieve our goals, our employees can feel a part of the success.” Creating a Motivating Work Environment Bernie Erven told us, “An individual’s ‘needs’ are what drives their motivation.” Edward Deci added, “The environment an employee is working in creates the conditions that allow him or her to be intrinsically motivated.” With this in mind, what are some actions a farm manager can take to create an environment where employees will be self-motivated? EMPLOYEE DEVELOPMENT if you’re dealing with people, you’ve got to communicate.” Build relationships through communication. Relationships occur between two people when they engage in conversations. Over time, each person learns about the other and begins to know what is important to them as individuals. John Noble of the Linwood Management Group, LLC, Linwood, N.Y., tells us, “When I meet employees in the course of the day, I speak to them. It doesn’t sound like much, but it really makes an impression on people when their supervisor or coworker acknowledges their presence. “I have heard of situations where the manager or the boss will just ‘grunt’ when he walks by. That sets the tone for that employee for the whole day.” Art Marquez, of Marquez Dairy LLC, Chino, Calif., comments, “Even if you are more of an ‘introverted’ person, you need to learn to talk with employees and build relationships that come from conversations. You don’t have to be ‘buddy-buddy’ with everyone. But, Provide opportunity for feedback and input. In addition to ordinary communications, employees also need to know how they are doing. They need to be given opportunity to offer suggestions and input. Sean Jones, of Jones Family Farm, Massey, Md., comments, “You need to be able to listen to employees’ ideas and give them the respect they deserve. If you shoot them down every time they offer an idea, the next time they are going to be hesitant to speak up.” Provide workable and safe equipment. Jesse Koopman, of WestPoint Farms, Wendell, Idaho, adds, “As owners, we like things organized. We like the facility to be neat. We want our equipment to be running properly. And, we want our farm environment to be safe. “When something is broken, we fix it. If a piece of equipment is missing a guard, we replace it. If there is trash on the ground, we pick it up.” Offer compliments and provide recognition. Dairy Producer Hugh Weathers, of Bowman, S.C., observes, “Everyone wants to do a good job. As a result, I believe they are more motivated when they feel like I notice the good things they are doing, and tell them so.” Don’t be a ‘grumpy’ boss. Joe Statz, Statz Bros. Inc., Sun Prairie, Wis., says, “If an employee comes up to you and can tell in your voice you are already mad about something, they will not be comfortable talking to you. However, if they come up to you and sense you are in a good mood, the conversation will go better even though you might say the same things.” The Carrot and Stick Motivational Method There has been a great deal written about the ‘carrot’ (hope of gain), and ‘stick’ (fear of loss) methods of motivating people. We asked farm managers which they believe to be more effective. Hank Wagner, Wagner’s Farm, Oconto Falls, Wis., responds, “I don’t think fear is the right button to push to motivate people. I think leaders ‘pull’ their people instead of ‘pushing’ them.” Lamar Anthony, Anthony’s Dairy, Americus, Ga., comments, “I’ve been on some farms where they assume if an employee doesn’t work out, they will just go out and hire another one. As a result, they drive their people with negative comments assuming ‘either he’s going to do a better job, or I’m going to send him down the road.’ “I feel if the person has some potential, I would rather work with him and uncover his motivation to do a better job. I just think positive motivation works better than negative motivation.” Hank Wagner concludes, “As supervisors, we need to find out what’s really important to an individual employee. We need to learn about their goals and find out what they really want to accomplish. Then, provide a working environment where they can achieve their goals by working on your farm. That’s how employees become self-motivated to do a great job.” Horizons | ©2006 CRI 27 by Amy te Plate-Church Market Development Manager Genex Cooperative, Inc. One year later, the PR had risen three to four percent. “When we started breeding with Genex, our goal was 35 percent Conception Rate. Now we are well above that goal,” Darin states. Ninety pounds milk per cow per day and a Pregnancy Rate (PR) pushing 20 percent are lofty goals. One dairy achieving these benchmarks is the 3,500-cow Dykstra Dairy at Maurice, Iowa. The key, explains owner Darin Dykstra, is to “do things consistently well, day-in and day-out.” This consistency starts by drawing up specific protocols for areas like reproduction, milking and fresh cow care. “I like working with the Genex team because they are conscientious about sticking to the protocols we have laid out,” continued Darin. “They definitely want to see us succeed, want to help us be profitable. We work together as a team toward the same goal – to have the best repro program we can.” The game plan expanded in early 2006, starting management team meetings with analysis through Genex RPM™, or Reproduction for Profit Manager. The quarterly meetings include Darin Dykstra, dairy employees, herd vets and reps from Monsanto and Genex. Darin describes the sessions as the time to analyze herd performance, discuss what is happening, consider improvements and decide on changes or new protocols. Continued on page 31 Working Together Works The kick-off was May 2005, when Genex began a complete reproductive service at Dykstra – detecting heats, inseminating and managing timed artificial insemination (A.I.). + Darin and Linda Dykstra and family “I like RPM because we see how we are doing, compare ourselves to other dairies and consider improvements.” walkways when the dairy was built in 2002. Genex Farm Systems recently added the rubber flooring in the double-44 parallel parlor. As a result, the management team improved the synchronization schedule and set a more aggressive protocol with “problem breeders,” those open at 150 Days in Milk (DIM). Over 700 fans and sprinklers cool cows through humid Iowa summers. Each pen has two rows of fans, with a fan every 24 feet. Sprinklers automatically mist cows when the inside barn temperature hits 70 F, and cows are misted more often as days get hotter. The End Result Simply said, the number of pregnancies at Dykstra is at an all-time high. To maintain current size (3,100 milking cows), Dykstra needs 50 pregnancies confirmed in cows per week. Presently, 56 pregnancies are created per week, which may provide extra replacements and more management options. Fine-tuned management and cow comfort are key reasons for Dykstra’s top results, says Chris Janssen, Genex Area Sales Representative. In the 12 freestall pens – each housing 260 cows – comfort is maximized with rubber belting, comfortable stalls and sand bedding. Rubber was installed over pen Having achieved their initial lofty goals, the DykstraGenex team will aim to raise the bar as they continually monitor herd performance, fine-tune protocols and consistently carry them out. REPRODUCTIVE PROTOCOLS in Dykstra’s Milking Herd Night herdsman watches for standing heats and secondary signs, utilizing a printed list of cows 18 to 25 Days Since Last Heat (DSLH). The next day, Genex breeds those found in heat. Horizons | ©2006 CRI 29 HERD STORY Consistency and Cooperation Breed Success HERD STORY Team “Clicks” at Allenwaite Farm “The whole system is just clicking,” explained Aaron Allen back in October 2005, Aaron is the seventh generation of the Allen family to manage Allenwaite Farm, Inc., a 1,000-cow dairy in Schaghticoke, New York. + Aaron is referring to the breeding program at Allenwaite dairy which, since April 2004, has included a team of Genex reproductive specialists. Together, Aaron and the Genex Riverrunners team, with Mike Schreiner as the primary Breeding Program Specialist (BPS)— increased the dairy’s pregnancy rate from 14 percent during an expansion phase to 23 percent. Services per conception have dropped from 4.7 to 2.6. “The response we saw with Genex was almost immediate,” said Aaron. “And we’ve been getting a pregnancy rate over 20 percent for almost every single 21-day period since.” There are many factors that make the reproductive program “just click.” The Riverrunners – consisting of Mike, Jesse Lamb and Bob Bain – and Aaron figured out what worked for the dairy and what didn’t. They then operated by what Aaron calls “a model of consistency.” The Repro Program Heat detection is a very important part of the reproductive program. 30 © 2 0 0 6 C R I | Horizons Use of the Ovsynch® protocol accounts for approximately 25 percent of breedings. The remaining 75 percent is from visual observations and the use of pedometers. “Having Mike here has really freed up our people for heat detection. Our heat detection rate is currently between 64 and 68 percent. Visual heat observations are usually conducted by the cow movers. Each one carries a card to record standing mounts,” said Aaron. Additionally, each cow wears a computerized DeLaval neck transponder, which includes a pedometer. An increase in activity can be an indication a cow is in heat or that she should be watched closely for further signs of heat. The neck transponders also allow for easy sorting of cattle. By simply entering a cow’s number into the system via the main computer or keypads on each stall in the rotary parlor, a three-way sort gate at the parlor exit can send cows back to their original pen, to the management rail and flush area, or to a separate smaller pen. The Allens have chosen to use young sire genetics within their herd. In recent months, they have joined the Genex QUEST program. Participating in the sire sampling program gives them access to young sires of the highest genetic level, while earning incentive credits for QUEST heifer calves and QUEST milking daughters. Growth over Time Since the first generation in the Allen family began dairy farming, farming the dairy has changed many times. The dairy was first started just up the hill from the current operation. In 1974, the first freestall barns and parlor were added. Since that time, the dairy has grown from about 450 cows to the current 1,000 cows. In 2003, the Allen’s incorporated a rotary parlor into their dairy. According to Aaron, the parlor can milk approximately 200 to 225 cows per hour, and the parlor efficiency would be maximized with 1,500 cows being milked three times a day. Therefore, with the reproductive program on track the goal for growth, this time internally, was set once again. Since Aaron made the statement about the whole system “clicking” in October, the dairy has continued to successfully grow reaching cow numbers much above 1,000. “Now, things are going so well at Allenwaite they need additional land and feed. In a matter of two years, we’ve taken them from not having enough cows to having so many cows they can’t feed them and can’t really expand. They are a herd that’s never been in this position before,” explained Mike.

Teamwork in Progress In the past month, the Riverrunners team has taken on a new challenge as they have become the “Tri County Settlers”. The team has grown from the original three to a six-man team with the addition of BPSs Ray Steidle, Dean Griswold and Kevin Ward. Genex teams, such as the Tri County Settlers, are often organized with a Aaron Allen team leader, one who organizes each day’s service calls and divides them between team members. Team members work together to make sure they meet the needs of all their member/customers in a timely, efficient manner. “Working in a team allows us to better serve members and customers,” said Mike, team leader. “Teams give us flexibility, allow us to use each individual’s abilities to the fullest, and best match each BPS to meet the needs and wants of a particular dairy. “There’s no question about it - in the long term, it’s going to work really well. Of course, to start with we’ll have our bumps in the road, but it’s a work in progress.” The Tri County Settlers now cover an area that extends about 70 miles north to south and 50 miles east to west in eastern New York and southwest Vermont. The team of six covers a vast area helping dairy producers make their reproductive programs “click.” The End Result Simply said, the number of pregnancies at Dykstra is at an alltime high. To maintain current size (3,100 milking cows), Dykstra needs 50 pregnancies confirmed in cows per week.
