Program they eat during their growth By: Ashley Fritz It’s been shown time and time again that early calf development impacts lifetime milk production. The successfulness of the dairy herd begins at the start of each calf’s life. Proper management is critical. If calves aren’t managed properly, they won’t reach their full potential once they are in the milking herd. From birth through six months of age, the calf/heifer requires higher levels of protein, for that is when she is most efficient in utilizing those proteins for frame growth and muscle development. The B.I.G. calf program takes advantage of this window of opportunity and offers calves/heifers higher levels of protein to meet their nutritional needs, improve immune function, and promote maximum growth. Animals must first meet their maintenance requirements before they can utilize energy for growth. With this period is critical. Naturally, calves are designed to drink their mother’s milk, which meets their nutritional requirements. Unfortunately, it is not always possible to feed whole milk to calves, so milk replacer is used as a substitute. Keep in mind that not all milk replacer is the same. Traditional 20/20 milk replacer (20% protein and 20% fat) is similar to feeding low-fat milk, which limits the calf’s growth potential. The B.I.G. 30/32 milk replacer (30% protein and 32% fat) is formulated to mimic feeding whole milk from early lactation cows. Feeding in this way promotes optimum calf health and allows for maximum growth. Whole Milk 20/20 25/15 28/19 26/28 30/32 Protein (13% solids) 3.2% 2.5% 3.0% 3.5% 3.25% 3.7% Volume 14 Issue 7 With a typical milk replacer, the calf is fed 1 gallon per day (2 quarts morning and evening). With the B.I.G. program, the calf is fed increased amounts of milk the older it gets. The goal is to get calves to drink as much as they can, increasing their caloric intake. What makes the B.I.G. milk replacer stand apart is that it is formulated to match the fatty acid composition of whole milk. To do this, cream and coconut fats are used as part of a unique fat blend. Unlike other milk replacers, calves on the B.I.G. program don’t get that false sense of being full, so they actually want to drink more, thus utilizing their full growth potential.

Grain Comments and Commodity Information to also deal with heat and humidity. Maximize your efforts and your management plan by keeping the very hot, humid times of summer in mind. CORN: On June 30, the USDA reported 91.6 million acres of corn to be planted, 4% less than last year and the fewest number of acres since 2010. Last year farmers had 95.3 million acres of corn in the ground. Despite few acres of corn, corn stocks were 3.85 billion bushels 39% larger than the amount reported on June 30, 2013. The increase in ending stocks number indicates the feed and residual corn use was less than projected. Furthermore, national corn crop ratings list 75% of the corn crop “good-to-excellent” compared to 67% last year and a 5-year average of 65%. So, with a large crop in the bin and the promise of a large crop to come, corn prices have moved lower and quite quickly. Current corn prices are $4.55/bu compared to $6.95 per bushel last year and $8.35/bushel in 2012. SOYBEANS & SOYBEAN MEAL The USDA surprised everyone with their expected soybean acreage to be planted – 84.8 million acres of beans are expected to be in the ground this year. This is 11% more than last year and if realized would be about 7 million acres more than previous record. Grain traders were expecting acres to top at 84 million acres. Soybean inventory was reported at 405 million bushels; which matched trader’s expectations. The effect of this news has already started to take effect as both soybean and soybean meal prices have started to drop. Current soybean value is $13.90/bushel; not too long ago prices were over $15.00/bu. . Trailer load prices on soybean meal are approximately $524/ton compared to $604.30/ton last year.

Important dates and reports to keep in mind for the future are: July 11th – USDA Crop Production Report August 12th – USDA Crop Production Report September 30th – USDA Grain Stocks Report Ron’s Points to Ponder Heat stress and the impact on cow reproduction Summer is officially here and now that it is upon us, let’s talk a little more about heat stress on our animals. The article I wrote for last month’s issue of “The Feedbag” had a lot to do with heat stress and in this article, I want to elaborate a bit more on the many challenges our cows go through because of the heat and humidity. A cow’s normal body temperature runs between 100.4 to 102.8°F unless she is fighting some type of infection that causes her to have a fever. Cows weigh approximately 1,250 lbs as a first calf heifer up to 1,600 - 1,700 lbs as a mature cow. Large Holstein cows can even weigh as much as 2,000 lbs. No matter her exact weight, that is a lot of body mass and muscle to try and keep cool. I’m going to share some information with you that was written by Faith Cullens from Michigan State Univer- sity in an article she wrote back in 2011 entitled, “Managing for reproductive success of dairy cattle during the heat”. Within this article, Faith makes some excellent points that relate directly to the hot, humid weather that we experience here in and around south eastern Pennsylvania. One point she makes is that that pregnancy rates in dairy cows can be drastically reduced when temperatures and humidity rise in late spring, summer, and early fall. Around here, our biggest heat challenge months tend to be June, July, and August, but don’t rule out the last two weeks of May or the first two weeks of September. One thing to always keep in mind is that cows will produce more body heat while they are lactating compared to when they are considered dry. I hear dairy producers say that their cows are really working hard. I think that some folks in the industry don’t truly under- By: Brad Wagner stand how much work a dairy cow puts out each day as she is trying to make 90 to 140 lbs of milk or more each day. During these hot periods of the year, lower estrus detection and conception rates are evident. Impaired egg quality and abnormal follicular function, including cystic and anovular (not ovulating) cows are abundantly evident. Early embryonic death is significantly higher when cows are heat stressed due to altered uterine environment, reduced blood flow to the placenta, and sensitivity of the embryo to elevated temperatures during the first three days after breeding. Many dairy producers try to get their herds synchronized so they breed the majority of their cows during the cooler months of the year. I know that it takes a few good years of excellent management to get that done but remember what it costs every time you don’t get a cow bred. Try to avoid having cows freshen during these hot months as the stress level for a cow during calving is extremely high, especially when having We talked briefly in last month’s issue about cooling cows with fans and water evaporation. Please do not underestimate the problems with heat stress. Good management techniques are the only way that a cow can get the advantage she needs to keep cool, milk at peak production, and get pregnant. Let’s talk a little bit about the effects of heat stress when breeding cows using your own bulls. Although bulls are sometimes used to help compensate for cows not showing signs of heat cycles, they cannot improve the altered uterine environment, blood flow to the placenta, or embryo sensitivity. In addition, bulls can also be affected by heat stress. They are less active, will breed fewer cows, and have lower quality semen. Just 2-3 days of exposure to temperatures over 85°F can reduce semen quality for at least the next 8 weeks. That can cost a whole bunch of money when attempting to get cows bred. One more thing I would like to point out in regards to heat stress is to always maintain a good, solid nutrition program. This is important year round but especially critical during the hot periods of the year. Remember, cows are going to eat less when it’s hot. Negative energy balance is correlated with impaired reproductive performance. When cows reduce their dry matter intakes as a result of heat stress and fall into that dreaded negative energy balance situation, there are negative effects on plasma concentrations of insulin, IGF-1 (stimulates cell growth), and glucose which results in poor follicular development, poor quality of oocytes (immature ovum, or egg cell) and reduced expression of heat. Minimizing dry matter intake losses during heat stress is critical. What does the term, “negative energy balance” really mean? It means that if a cow is burning more calories a day than what she is taking in through her diet, she is going to start losing weight. That’s why cows oftentimes thin down when milking their heaviest; they simply cannot eat enough to keep up with the work load they are performing. If a cow burns more calories than what she takes in, you are going to have real challenges in getting her bred. Cow’s thinning down during the peak of their lactation can be a challenge all year round, but if it is also occurring during very hot weather, the challenges can be even more significant. That is why it is so important to keep dry matter intake under control (as high as possible) when the weather is hot. Keeping cows cool will result in cows eating more and reduce slug feeding intakes. It is important to feed fresh feed more often, place extra waters in return alleys, and provide as much shade as possible in and around the bunk area. Another good management tip is to use an acid additive in the TMR that will reduce heating after the TMR mix is fed. Please review your ration before the heat is at it’s worst and be pro-active in helping to control these stresses within your herd. Adding some extra water to the TMR or adding additional water stations so that cows can drink more will do a lot for a cows’ well being. Studies show that if you can get 7 - 8 lbs (approximately a gallon) more water into your cows each day, she will eat 1 more pound of dry matter. In turn, that will translate into 2 more pounds of milk which today is around 45 - 50 cents more cash flow per cow. If you can achieve 50 cents more income per cow per day in a 60 cow herd, that is $10,950/year! Meet Ashley Fritz “ Lastly, for those that are currently not feeding a P-1 Program with us, now would be a good time to consider doing so. The P-1 Program in and of itself helps cows cope better with the stresses of heat and humidity, in addition to many other added health bonuses. Ask your Hoober Feeds Representative to explain the advantages seen by many dairy producers across the country and around the world when feeding the P-1 Program. Until next time, “Keep Lookin’ Up”! By: Ron Moore What You Don’t Know (continued) there is a challenge we may need to put several types of binders into the feed to get full coverage on the various toxins that might be in there. 5. Now is good time to evaluate your storage facilities and harvest practices to see where you might be able to improve. You might not be able to reduce the amount of toxins coming in from the field, but proper harvesting and storage will go a long way towards preventing the problem from getting worse once the forage/grain is harvested.

(Offer on Day 4) ¼ lb. ½ lb. 1 lb. 1 lb. 2 lbs. 4-6 lbs. 6 lbs. This chart is breakdown of how the calves should be fed on the B.I.G. Program. The key to this program’s success is the higher liquid feeding levels (with high protein and fat content), combined with the right starter grain that compliments feeding more milk, and followed up with a grower that promotes lean growth. Grain consumption encourages rumen development and growth. If the rumen is not properly developed, the calf will have a hard time transitioning from milk to grain. Both the B.I.G. Calf Starter Pellets and the B.I.G. Heifer Grower Pellets are designed to meet the calf’s needs, improve her immunity, and promote lean growth from birth through weaning and beyond. The goal is to match the grain with key amino acids to grow frame size and lay down lean muscle tissue instead of fat. At the same time, the grain is made up of a blend of carbohydrates that are utilized as energy sources. The starter contains lactose and soluble fiber and is low in starch. Because the starter and grower pellets provide plenty of calories, vitamins, minerals, and amino acids, calves are going to have healthier immune systems, which will result in less illness and lower treatment costs. The starter pellets are highly palat- able and very digestible. B.I.G. Calf Starter Pellets are 21.6% protein, 3.4% fat, and 9.1% crude fiber. The starter is designed to improve rumen papillae development. Papillae are finger-like projections that increase the surface area of the rumen and allow for better absorption of nutrients. The longer the papillae are in length, the more efficient the animal is, allowing for better nutrient uptake. When the rumen needs to be responsible for nutrient uptake, it is crucial to have good papillae there to work with. When the papillae growth is weak, calves will stop growing, stall out, or even go backwards. The improved papillae growth from the B.I.G. starter will allow for a smooth weaning transition, avoiding the typical post-weaning growth slump. Starter pellets should be offered to calves on day 4 and fed increased amounts as they get older. Once weaned, they should be fed 6 lbs per day. The B.I.G. Calf Starter Pellets are 21.6% protein, 3.4% fat, and 9.1% crude fiber designed to improve rumen papillae development. The grower pellets are also highly palatable and digestible. The B.I.G. Heifer Grower Pellets are 25.6% protein, 3.9% fat, and 6.0% crude fiber. The grower is formulated to meet the heifer’s needs, while promoting maximum growth. It’s no surprise that feeding higher levels of protein allows for calves to gain more body mass. Because this is still a critical period for growth, it’s important that calves receive adequate amounts of protein. Grower pellets should be fed from 3-6 months of age at a rate of 6 lbs per day. There is more to the story than just growing bigger calves at a faster rate. While the larger frame growth is very exciting, there are actually other noteworthy benefits that are related to this outcome. Nutritionally, what makes calves grow big is also what makes them healthy. Amino acids that are formulated in the grain are building blocks of protein, and protein is what grows bones, muscle, and boosts the immune system. The amino acids in the grain allow for high levels of T-cell production. T-cells are what keeps the immune system healthy and strong. Growth is actually an effect of the calf having a healthier immune system and can be used as a measure of health. While the B.I.G. milk replacer is more expensive than other milk replacers on the market, please don’t let the price tag scare you away. The initial investment put into your calves will pay off when you are able to breed heifers at a younger age. The average heifer calves at about 26 months of age. Using the B.I.G. program, calving should be easily attained by 22 months. This earlier calving age allows for fewer days on feed, as well as having them enter the milking herd sooner. Heifers will be making you money sooner, rather than just raising feed costs. Studies show that heifers that calve at 22 months actually produce more milk than those that calve later. - more on the back Average actual 305-day milk production by age at calving of Holstein heifers that began their first lactation in 2011 in Pennsylvania. Data from DRMS, Raleigh, NC. In addition, calves on the B.I.G. program have also achieved increased milk production throughout all lactations. The way the calf is fed actually determines how her mammary gland develops, which in-turn determines how much milk she will be able to produce over her Expect to see healthier, bigger, taller, leaner calves with more muscle tone; less treatment days; shinier hair coats, consistent growth, uniform body condition and consistent manure from calf to calf.

Because the B.I.G. program feeds for more nutrients above maintenance, the calf is actually being setup to be a better lifetime producers. The more milk your cows produce, the more profitable you become in the long-run. Herd-life can be enhanced through better early life nutrition. What You Don’t Know... By: Tom Nauman There is an old saying that goes “what you don’t know won’t hurt you”. The origin of that saying goes back to the idea that if we don’t know something then we won’t be able to worry about it. However, we know that the old saying isn’t true. This is especially so when it comes to toxins in our feeds. Toxins in forages and grains are very real and we at Hoober Feeds have been learning a lot about them lately. Our education has been aided by a new testing program that has been made available to us by the folks at Alltech. The testing program is called 37+ and it utilizes technology that allows the lab to determine levels of over 37 different toxins that are typically found in various feedstuffs. Over the last several months we have run a number of these analyses on TMR samples from some customers that have had problems that have been a challenge to solve. Through these samples we have learned a number of lessons that we would like to share with you. 1. Feed can look sound but still have toxin contamination. The samples of TMR’s that we submitted did not show visible signs of mold growth. In fact, in most cases we were hesitant to run the tests because when we evaluated the odors and looks of the forages, there was nothing to be suspicious about. They did, however, have higher than normal counts of mold and/or yeast spores. 2. Animals react differently to different toxins. You can go to a text book and see normal symptoms to various toxins, but the reality is that every animal has a different level of tolerance to toxins and a different rate of recovery when the toxin challenge is removed. The main organ for filtering out toxins is the liver. The liver is also the main organ involved in energy metabolism. In addition, the liver is also involved in immune function. Therefore, mid and late lactation cows might be able to handle a toxin load that could not be handled by a fresh cow. The liver on that fresh cow is already maxed out with processing energy for the cow and helping her to try to stay free of disease. Sometimes we discount the idea of toxin challenges because our assumption is that if all of the cows are eating the feed, they should all be sick. The reality is that cows that are not under stress will not show as much trouble with toxins as will the cows that are under stress. 3. Toxin challenges are probably here to stay. I remember being in a meeting almost 30 years ago with DR Lon Whitlow, a mycotoxin specialist from North Carolina. I remember his words very clearly, when he said to us in that meeting “We’ve got ‘em in North Carolina and they’re coming your way. You better be ready for ‘em.” What we now know is that the majority of these toxins are produced during the growing season out in the field and we simply bring them into our storage facility. 4. We may need to rethink our binder strategy. There are different types of toxin binders and they have different modes of action, therefore they have different toxins that they can bind.
