2012/13 Charolais Magazine – Summer (part 2)
Tocal Beef Cattle Assessment Course By Keiley O’Brien, Gulargambone This year I was fortunate enough to be awarded Grand Champion Junior Judge at the 2012 NSW Charolais Youth Stampede. As part of my prize I was offered a scholarship by the Charolais Society to attend the Tocal Beef Cattle Assessment Course. The course was organised by the New England Angus Breeders Society and held on the 2nd – 3rd of October, on ground, at the Tocal Agricultural College. The two days were jam-packed with a mix of theoretical and practical experiences. After an hour of being at the course we had already started participating in in-depth lectures about the major components that make up a beef animal. We also further learnt about structure, genetics, Estimated Breeding Values and other core elements that play a key role when assessing livestock through presentations run by Bob Dent, of Bob Dent Cattle Services. The amazing amount of knowledge that Mr Dent shared within these presentations was outstanding and definitely allowed me to grasp a better concept of beef judging. The experience didn’t stop there though. After sitting inside, viewing and listening to those demonstrations that outlined critical guides of what to look for in beef animals, we would then travel out to the cattle yards on site where many different classes of cattle that varied greatly in breed, sex, age and target markets would be awaiting. Before commencing immediately with assessing the class before us, we would be given a scenario that our placing’s would depend on. Again, like the cattle, these scenario’s varied greatly. Over the short two days we went from judging bostaurus steers with criteria that they would go to the local butchers within the next fortnight to be slaughtered, to bos-indicus steers that were to be long feed for 120 days to meet the Japanese heavy export market and be inside the B2 carcase weight and fat specifications. We would then jump to judging heifers and cows that were: to be culled and kept; be serviced by different types of bulls for their off-spring to meet different types of markets; and be evaluated with their estimated breeding value’s. And of course this continued with the bulls as we faced many different situations wanting many more different outcomes. For every class, we would number the cattle before us from 1st – 4th and answer a minimum of 5 questions which would really make us think and look closely over the cattle. While our thoughts were still fresh in our mind, over judge Steve Chase, Waitara Angus, would tell us his placing’s, answers and discuss the reasons with us. By just listening to Steve, let alone all the other entrants of the course, I learnt an incredible amount and have improved my ability to asses and judge beef cattle by a great amount. Reflecting back over the two day course, I am very grateful for the opportunity that I received and would once again really like to thank the Charolais Society for the outstanding experience that I was lucky enough to receive. I would also like to recommend the course to anybody of any age and any level of experience who wants to better their beef cattle assessing skills and knowledge of the industry from either a stud or commercial perspective. The Tocal Beef Cattle Assessment Course really is an eye-opener and definitely worth doing, along with the NSW Charolais Youth Stampede. I had a great time at the 2012 NSW Charolais Youth Stampede and am already looking forward to attending again in 2013. The NSW Charolais Region did a fantastic job at hosting the event for the first time and combined a great mix of educational activities among with junior competitions. To any youth enthusiast out there no matter what your experience, I encourage you to come along. The 2013 NSW Charolais Youth Stampede will be a great chance to learn about the beef industry and Charolais breed in particular, along with making some inside connections and friends. Entries are now open. Hope to see you there. n 26 CHAROLAIS MAGAZINE > SUMMER 2012/2013 Youth Stampede in Bathurst The NSW Charolais Region is once again hosting the NSW Charolais Youth Stampede, which is an exciting 3 day camp giving youth aged 8 to 25 years the opportunity to learn from well known industry experts and develop their skills in parading and judging. It’s a fantastic networking opportunity and a bit of fun as well! The program caters for all levels of experience and is based around hands-on practical activities. The main theme for the 2013 Stampede is Artificial Breeding and several heifers will be Artificially Inseminated during the camp. The 2013 Stampede is being held at the Bathurst Showground from Thursday 24th to Sunday 27th of January. An overview of the program is shown to the right. The program may vary depending upon the number of participants, their ages and levels of experience. Keiley O’Brien was our Grand Champion Junior Judge at the 2012 Stampede, which won her a place in a Tocal Judging School course. Her story and experiences at the Stampede and the Tocal course are a great testament to the opportunities the Stampede provides. Congratulations Keiley on an impressive win! The Stampede will cost $120 per entrant and includes accommodation and catering for entrants. Registrations close on Friday the 14th of December 2012. Numbers are limited and with the Christmas period fast approaching, make sure you get your forms in soon! Late entries will be accepted, however late entrants will not receive a Stampede shirt and will also incur a late entry fee. To register please visit the Charolais Society website and download the Registration Pack – www.charolais.com.au/nsw-youth-stampede Sponsors and supporters are also invited to be a part of this great youth event. Such an event is not without expense and it is by no means run as a revenue raising exercise.

Meet our Regional Chairmen. They all come from diverse backgrounds, operate within unique production systems and work towards different breeding goals, however they all have one thing in common - A devotion to Charolais. This is your opportunity to get acquainted with your regional representative. Don’t hesitate to make yourself known to them if you see them at the show. Chris Knox, Chairman, NSW Region Chris and his partner Helen Alexander run DSK Angus and Charolais based at Coonabarabran in NSW. Chris has been the Chairman for the NSW Region since 2010 and is also Co Vice President of the Charolais Society. Showing experience: Have been showing cattle at Royal shows for over 40 years & have judged major breeds at every Australian mainland Royal show & most major breed national show & sales. Top tip: Don’t rush the program. A slow preparation over a long period is the way to go. What not to do: Don’t knock other exhibitors cattle because you are there to promote the breed. Look for positives in cattle. Showing highlight: Winning the Hordern Trophy twice at Sydney Royal. Being the first to do so for the Angus breed & doubly so because the cow was all homebred, not from an AI sire. Jim Wedge, Chairman, QLD Region Jim and his partner Jackie Chard, run Ascot Cattle Co. based at Warwick in QLD. Jim has been the Chairman of the QLD Region since 2011. Showing experience: We have a small number of show cattle as our main focus is on breeding for commercial traits and we believe that showing does not always demonstrate the full genetic ability of an animal. Top tip and What not to do: When preparing cattle for a show it is important to not overfeed them, especially females as they can develop too much fat in their udder which can lead to milking difficulties as they get older. Showing highlight: My most memorable moments were winning the Interbreed Grand Champion Cow at the 2012 Brisbane Royal Show, and winning Grand Champion Cow and Exhibit at the 2012 Sydney Royal Show. Michael Osborne, Chairman, SA Region Michael and his wife Julie, run Ryeview Charolais based at Millicent in SA. Michael has been the Chairman of the SA Region since 2011. Michael is also a federal Council member. Showing experience: We do not show our Charolais, we do however show our Ryeland and White Suffolk sheep at shows with success. Top tip: Have your stock fed to their best and well broken in to tie up and lead quietly. Untrained stock at a show can be dangerous and even sheep can hurt & break bones. What not to do: Don’t talk about others stock if you can’t say anything good or act as if you know it all, as it will all come unstuck when you are showing your animals. Showing highlight: Wining our first championship!

Chas has been the Chairman of the VIC Region since 2003. Showing experience: My experience in showing cattle has been focused on carcase competitions. Top tip: Be sure the cattle you select have the right breed characteristics which are industry focused. Always remember that you have to be competitive and preferably winning! Showing highlight: Greatest thrill was being a member of the Royal Melbourne Show Borthwick Trophy team of three head in 2005. We exhibited one steer along with Ashwood Park and Longerenong College, whose steer we had also bred. We were the first Charolais team to win the trophy for twelve years. Another memorable event for me was to judge at Whittlesea Show. Michael Osborne Chas Armytage Robin Yost, Chairman, WA Region Robin and her husband Kevin, run Liberty Charolais based in Toodyay in WA. Robin has been the Chairman of the WA Region since 2011. Showing experience: We have shown cattle at most local shows, Perth Royal, Sydney Royal, Rockhampton Beef Expo and the Charolais National Show & Sale. Robin Yost Heath Dobson Heath Dobson, Chairman, TAS Region Heath along with his father Denis, run Pine Park Charolais based at Cluan in TAS. Heath has been the Chairman of the TAS Region since 2002 and is also Co Vice President of the Charolais Society. Top tip: Be organised. Things flow along so nicely if you’re organised. Showing experience: The stud has been showing since I was born and I have been judging at different shows in TAS for the last 12 years. What not to do: Don’t treat your cattle harshly. Show cattle are very forgiving creatures. They are extremely tolerant and deserve to be looked after well. Top tip: Break the cattle in before they go to the show. Start earlier than you need to, then by the time you do actually start preparing it is not too close to show day! Showing highlight: Winning Grand Champion Charolais Bull at a Sydney Royal, and a number of Interbreed Champions at the Perth Royal. This year winning the Supreme Interbreed Junior Champion female was a great thrill. What not to do: Don't assume that the show will break the cattle in for you! Showing highlight: Winning the National Judging Finals. Don’t be left BEHIND ...

They will be applied first in the December 2012 Trans-Tasman Charolais GROUP BREEDPLAN analysis, then in all subsequent analyses. By Christian Duff The enhancements include: • Transition to a full crossbred analysis model - With the growing frequency of Charolais-content crossbred animals being performance recorded and available for the Charolais analysis, the model used will be changed to allow the performance records available on such crossbred animals to be included in the analysis. Importantly, this will allow the performance data collected in BIN progeny test herds (primarily Angus x Charolais or Brahman x Charolais animals) to be included in the monthly analyses. Records will be pre-adjusted for both direct and maternal heterosis based on breed content of calf and cow. These changes mean that contemporary groups may now comprise both purebred and crossbred animals, allowing head-to-head comparisons where such breed types are being run together. • Upgrade to BREEDPLAN Version 6.2 – This latest version of the BREEDPLAN software has several enhancements including a revised method for handling different groups of “base” animals (as outlined below) and the ability to “blend” genomic prediction information into the analysis. Note that genomic prediction information is not currently being included in the Charolais analysis, however the pathway is available through version 6.2 to allow this to happen when genomic predictions relevant to Australian Charolais are available. • Revised method for handling different groups of “base” animals – animals without complete pedigree in the BREEDPLAN analysis are referred to as “base” animals and the analysis must determine how to allocate a “solution” for the contribution from the unknown parent/s. In the current Charolais analysis, base animals represent different periods (historic vs current) and countries (Australia and New Zealand, as well as imported genetics from Europe and North America) and breeds (as used to create cross-bred Charolais genetics such as the BIN progeny). A revised method for handling these different “genetic groups” of base animals has been implemented in the upgrade to BREEDPLAN v6.2. This has resulted in an increased number of genetic groups. Animals within each group are assigned a starting value equivalent to the average EBVs of the group. As additional information becomes available for an individual animal (e.g. progeny performance) the EBVs will change to reflect this information, including an increase in EBV accuracy. • New Genetic Parameters - The genetic parameters and adjustment factors utilised within the Charolais GROUP BREEDPLAN analysis have been re-estimated by the Animal Genetics & Breeding Unit (AGBU). The genetic parameters include the heritability of each trait and the correlations between the different traits. The adjustment factors are those required for the performance records to remove the non-genetic effects of age and age of dam. This included all traits apart from calving ease direct, calving ease daughters and the direct abattoir carcase traits. The re-estimation of genetic parameters is a standard practice that is undertaken periodically for all breeds. It ensures that the BREEDPLAN analysis is kept relevant for the given cattle population, in this case Charolais. Please Note: The above enhancements will result in EBVs and Selection Indexes changing. In some cases, the rankings of animals may also change. If you have any questions regarding the enhancements to Charolais GROUP BREEDPLAN or changes in EBVs resulting from the enhancements please contact: Christian Duff Charolais SBTS Technical Officer P: 02 6773 2472 E: christian@sbts.une.edu.au or Charolais BREEDPLAN P: 02 6773 3555 E: charolais@breedplan.une.edu.au CHAROLAIS MAGAZINE > www.charolais.com.au 31 BIN Results - Meat Science The meat science data on the first cohort of Charolais by Angus progeny in the BIN project show a spread of results that are very interesting. The steers that were grain fed for 74 days produced low shear force values with 98 per cent of the samples coming in under 5 kilograms and 80 per cent under 4 kilograms of shear force. Lower shear force scores imply that lower pressure was required to cut the meat sample. Studies have shown that 50 per cent of consumers report that steak is acceptably tender when it is below 4.4 kgs shear force and 68 per cent say it is acceptably tender if it is less than 3.7 kgs shear force. The pasture fed steers shear force results were more variable relative to the grain fed steers with 84 per cent testing below 5 kilograms and 55 per cent testing below 4 kilograms. The correlations between shear force and other variables for the steer data is shown in table 1. Carcase weight and shear force were not correlated at all. The correlation with rib fat and marbling against shear force was also very low at 0.06. This result supports conclusion that subcutaneous fat (rib and P8) and marbling does not increase tenderness. Intramuscular fat (IMF) and shear force were slightly more correlated at -0.162 which indicated that as IMF increased then shear force decreased. The effect of ossification was stronger than marbling and rib fat but ossification does not feature in price grids even though it is a better predictor of tenderness than the “fat” measures such as marbling or rib fat. Larger eye muscle area is correlated to lower shear force values and this confirms the results reported last year by Murdoch University. The variable with the highest percentage of correlation to shear force was muscle pH. Muscle pH is a measure of the level of acid in the muscle profile and this acid breaks down the actin and myosin protein bonds which lock fibres together and this process increases tenderness. The correlation was -0.29 which indicates that 29 per cent of the variation in meat shear force is explained by muscle pH. Therefore when pH was higher (less acid) the meat was tougher and when pH was lower (more acid) the muscle was more tender. There was a correlation of 0.18 between pH and carcase weight which indicates that heavier carcases produce more acid; however, we did not find a significant correlation between carcase weights and shear force. The correlation between pH and eye muscle area is stronger than any of the other correlations which indicates that larger muscle areas produce more acid which increase tenderness. The level of intramuscular fat contributes to the level of acid (0.216) but muscle area is a much better predictor of tenderness. The important message to get from these results is that Rib and P8 fat are very poor contributors to tenderness and those carcases with larger muscle areas and lower ossification scores will produce more tender 32 FACTORS CORRELATION SF with Weight -0.001 SF with Ribfat -0.063 SF with Marb -0.066 SF with IMF -0.162 SF with Oss 0.107 SF with EMA -0.249 SF with pH SF with UpH 0.291 0.294 pH and Weight -0.184 pH and EMA -0.300 pH and IMF -0.216 Table 1: Correlation between Shear force (SF) and other carcase traits.

Japanese and Korean consumers will no doubt come to this same conclusion sometime soon. The graphs below show the relationship between intramuscular and shear force.

Table 2: Meat science results by sire (Grain fed 74 days) The meat science results by sire vary according to grain or grass feeding. The progeny of some sires are spread evenly through the distribution. The results for the grain fed progeny show that they all had acceptable muscle pH (below 5.6). The L, A, and B colours were all fine. Cooking losses were good at 23 and shear force values were very good at 3.55 kgs. The progeny from Paringa Rio Bravo were slightly higher for shear force but still acceptable. The grass fed results indicate that Elgin Columbo’s progeny had high muscle pH but their shear force values were fine. The L, A and B values were a little lower for Elgin’s progeny but they were still acceptable. The cooking loss was lower for Elgin’s progeny given the high pH; however, the loss was still inside the acceptable range. Paringa Grid Maker’s progeny had higher shear force values on the grass fed results and lower values on the grain fed results whereas Paringa Rio Bravo’s progeny had higher shear force values on grain and were lower on grass. Table 4 shows that there was no difference between the ossification scores of progeny on grass or grain feeding. The average score was 139.6. Eye muscle areas were 6.6 cm2 larger in the grain fed progeny versus the grass fed progeny. MSA Marbling scores were lower for grass fed animals at 336.7 relative to grain fed at 365.8; however, the level of marbling in progeny of some sires was higher when grass fed: these sires were Lt Easy Blend and Paringa Rio Bravo. Colorado’s progeny exhibited the largest difference in marbling from grain feeding relative to grass feeding. This data will now be loaded in to BREEDPLAN and will be included in the next run in December. The next lot of meat science data from the second cohort progeny with Charolais over the Brahman cow base will be available at this time next year. n SIRE pH L A B Cook Loss SF IMF Paringa Rio Bravo D213E 5.62 38.96 22.48 10.15 22.99 3.52 2.66 Elgin Columbo 5.93 37.78 20.03 8.86 19.66 3.62 2.08 M6 Grid Maker 5.58 38.61 22.29 10.41 22.99 3.78 2.86 Ashwood Park Aristocrat A12 AI 5.62 38.40 22.54 10.47 21.88 3.91 2.85 LT Easy Blend 5.62 40.40 23.31 11.14 23.04 3.97 2.24 Colorado C26 (NZ) 5.67 38.65 21.56 9.84 22.80 4.32 2.74 Paringa Pinay D194 AI ET 5.62 39.91 22.28 9.92 23.19 4.73 2.45 Paringa Grid Maker D190 AI ET 5.65 38.49 20.94 9.46 22.21 5.02 2.11 LT Thundering Wind 5.62 37.50 20.86 9.29 23.42 5.27 1.96 TOL D184 5.69 39.41 22.37 10.46 21.34 5.38 2.26 AVERAGE CHAROLAIS 5.66 38.70 21.90 10.07 22.37 4.35 2.38 pH=Muscle pH, L=light colour, A= red colour, B= Brightness, Cooking loss % by weight, SF=Shear force, IMF=Intramuscular fat percentage.

" Changes to DNA collection and reporting From January 2013 the Society will move away from DNA testing animals with microsatellite markers to using SNP markers. SNP markers provide significantly more detail on the DNA of animals and the sequences can be used to run multiple tests. Microsatellite analysis was a process that amplified fluorescent signals from tissue samples (mostly hair). This method enabled 18 alleles to be identified by electrophoresis which separated the alleles by their length. The presence or absences of particular allele was then used to parent verify animals and these could also be used to identify a limited range of disorders. The lab sometimes ran into problems when two animals had similar parents or grandparents in identifying a unique match to a parent. The new SNP analysis detects chemical signals that identify pairs of Adenin and Thymin, or Cytosin and Guanin which reside at a particular point on a gene which is sequenced from a chromosome. These SNP pairs are then related to phenotypic data which provide markers for particular traits. This new DNA method provides a much richer source of data to detect phenotypic information. The Society will therefore allow parent verification to be tested using microsatellite (progeny) to microsatellite (sire, dam) tests for a period of four years. Progressive studs may wish to SNP test older animals to speed up the process for SNP (progeny) to SNP (sire, dam) verification on their young animals. GeneSeek offer a 10K DNA profile chip which is the least expensive DNA test option. Illumina has a 50K DNA profile chip and this profile will be useful for those studs that wish to move into higher density testing. This 50K SNP chip produces more data and this profile will enable the analysis of more alleles when new markers are identified in the future. The Society recommends that studs test their top sire and dam lines with the 50 K chip and other lines with the 10 K chip. Igenity have a horn-poll test which will be useful for those seeking homozygous polled animals. A coat colour test is available. The testing process requires that a hair sample is sent to the Society and the Society then sends this to a lab. Most members will not notice a change in the testing protocol. The lab extracts DNA from the follicle end of the hair and the DNA is put onto a glass slide which has numerous holes and then a machine reads the chemical signals from the DNA in these holes and the chemical signals then identify the sequence of Adenin (A), Thymin (T), and Cytosin (C) and Guanin (G). The output from the machine is similar to the diagram above right. This output would represent one side of the helex (either the red or green helex in the diagram below). From January 2013 all DNA will be analysed with the new SNP test. Labs will not be able to do a parent verification test by comparing SNP markers to microsatellite marker sets. Therefore in order for a calf to be verified by SNP markers both parents will need to have been tested by using a SNP profile and obviously we can only do this when we have hair, semen or tissue samples on parents so this will rule out dead animals. The myostatin panel test provides a test for 9 myostatin mutations. Myostatin restricts muscle growth which can result in animals with “double muscling”. Some breeders actively seek animals with the double muscle moystatin haplotypes. A haplotype is simply a collection of alleles and alleles are one side of a pair (either an A or T or a C or G). Charolais cattle have the Q204X mutation which enables larger muscle growth. The Q204X mutation is common to Charolais and Limousin. Limousin also carry the F94L substitution and nt821 deletion. Other French breeds carry a different set of myostatin mutations. The Q204X mutation is the T allele in the second line which is in the place of a C allele in the first line. Haplotype: GGTATTTGGCAGAGCATT GGTATTTGGTAGAGCATT Gene companies are regularly testing gene sequences for new haplotypes. While much of the work is currently being conducted on human data there are cross over benefits to the cattle industry and this is reducing prices for SNP testing and animal research. The SNP data for each animal will be copied into a database and that database can be used by AGBU and other researchers to identify new traits for Charolais and other breeds. This move to SNP testing will also reduce the time frame to move to genetically assisted (gebvs). n PRICES FOR TEST FROM 1ST JANUARY 2013 (Prices per animal) • Microsatellite parentage profile ($33 sire, dam and calf) $11.00 • GeneSeek 10K profile (GGP) $43.00 • Illumina SNP50 profile $80.00 • 96-SNP Parentage profile $15.00 • Igenity Horn-poll $40.00 • Coat Colour $10.00 • Myostatin panel $20.00 CHAROLAIS MAGAZINE > www.charolais.com.au 35 Australian rights Australian rights owned owned b by yK Kandanga andanga V Valley alley a and nd C Charnelle harnelle Charolais.

Since founding the Rangan Park herd in 2005, the family have bred the number one ranked domestic indexing female in the breed, had a young sire selected for semen sales by an AI company, have numerous bulls working in studs around Australia, and established a successful on-farm bull sale that earlier this year averaged $4400 for 30 head. Add to this their record of topping Victoria’s largest summer weaner sale at Wodonga in 2010 and 2011 – at up to $915 for Charolais Angus-cross steers sold in January 2011 – and it is an impressive CV. The Rangan Park story started with a targeted buy-up of proven Charolais matrons from leading studs. Graeme doesn’t shy away from the fact they spent about $200,000 on 20 foundation cows in the early years. Their key purchase, he said, was 13 older and proven females, aged 10 to 12 year olds, from Palgrove in 2005. The cattle industry, however, has its share of stories about people who spend big on stud animals but fail to make much of a mark within their chosen breed. To mould together a high performance herd and build a brand, even with some top individual cows, takes passion, an eye for detail, as well as business and marketing acumen. THE DECISION WAS WHITE Graeme, his wife Liz and children Laura, Ellen, Claire and Jessica are the third and fourth generations to farm the family property By Jenny Kelly at Sandy Creek in Victoria. It comprises 500 hectares of rolling hill country in a high 30 inch rainfall zone. They lease a further 120ha. Graeme, who worked in the wholesale and retail fuel industry for 24-years before returning to the farm, said they began looking at breed options after becoming disillusioned with the returns from their commercial Angus herd. “We weren’t getting the prices for our Angus heifers that I would have liked – they were either over-fat or too light and then discounted in the market,’’ he said. So like other producers, they began using Charolais bulls over their Angus cows to get more weight and shape into their calves and the chance of capturing similar money for heifers as for the steer drop. Today the Cook’s run 150 Angus and Angus-cross cows, with the Charolais sired calves sold at the New Year weaner sales and as vealers to the domestic slaughter market in the autumn. All the calves are sold by 10-months of age. They then ventured into stud breeding after finding it difficult to source the type of Charolais bulls they wanted in the local area. Graeme said one of the “challenges’’ of Charolais cattle, both for breeders and potential bull buyers, was the vast range of animal types within the breed. “There is more variation within the Charolais breed than any other cattle breed,’’ he said. “You have the heavy boned, latter maturing full French types through to the polled early maturing American animals, and then everything in-between. “The key is to work out what suits the market you are breeding for so you can sell bulls into that market.’’ Breed variance is one reason why Graeme said they invested in older stud cows that had the depth of breeding and performance to give a more consistent outcome. CHAROLAIS MAGAZINE > www.charolais.com.au 37 stud profile (cont.) Even then, he is honest enough to acknowledge that some of the high priced cows they bought didn’t live up to their expectations. “Some of these females have been fantastic and some have been failures,’’ he said. “Thankfully the fantastic ones have outweighed the others and we were able to quickly assess each one and multiply the genetics that were performing for us through extensive AI and ET programs.’’ A success story has been the cow Palgrove Showgirl 6, which the Cook’s paid $11,500 for as an 11-year-old in 2005. Since then she has generated over $250,000 in sales for Rangan Park and has been flushed 21 times for over 300 useable embryos. THE RANGAN TYPE Graeme said their clientele was mainly commercial farmers running British beef cows and using Charolais bulls as a terminal sire, with the aim of producing calves that can be finished within a time-frame of 10 to 15 months of age. For this they need a balance of growth and carcass substance, along with adequate fat cover and finishing ability, as well as the ever present demand of calving ease. Graeme said they tried to blend the best of Australian, French and American genetics to create an animal that could deliver to these specifications under Australian conditions. “The French Charolais generally have the bone, eye muscle and carcass yield, while the American animals generally bring in shorter gestation, lower birth weights, larger scrotal, and extra fat cover in an earlier maturing pattern,’’ he said. “We have settled on around 25% French as our ideal Charolais.’’ Andy Whitsed from Merial, presents Graeme Cook and his daughter Ellen with their prize for winning the best pen of Charolais weaner calves at Wodonga in January 2011. 20 Steers averaged $915.

A bull Rangan Park has recently used is the Canadian sire Harvey Redemption. Graeme said they researched the bull on the internet, found out who held the Australian breeding rights and spoke to them about how the bull was breeding and inspected progeny. “From this research we knew he was polled, had good structure, temperament seemed sound and he had solid performance numbers,’’ he said. “We decided to use him over cows with plenty of natural thickness and reasonably early maturing types, as some of his progeny seemed a little late maturing for our breeding program. “To this end we had a flush that worked extremely well out of one cow, but not so well out of another. But at least we know enough about the bull now to be reasonably confident on how best to breed him.’’ Graeme said match-making genetics was both rewarding and frustrating. He said the lack of information sharing between Australian studs on how new release bulls were performing, particularly overseas sires, was an issue he would like to see improved. talking points... There is no doubt Graeme Cook is passionate about Charolais cattle, so we asked him to discuss some of the key issues he believes the breed needs to talk about and potentially tackle. US SIRES AND STRUCTURAL SOUNDNESS “I’m getting extremely frustrated with the structure of a lot of the new beaut AI bulls coming out of the US. Their progeny are fine at 12 to 18 months of age, but by three years they are culls. They might have great performance numbers but if they can’t walk at three then they are no good for our conditions. At Rangan Park we manage this risk by only putting a maximum of 25% of our cows to these unproven bulls, as well as culling our females very hard for structure. But it is something the industry needs to look at.’’ CATTLE THAT JUST DON’T PERFORM “I’ve made plenty of mistakes but as long as you learn from them that is OK,’’ he said: “If more breeders were willing to network and share information about what bulls are working and what aren’t it could really help take the Charolais industry forward and reduce the number of animals being bred that can give the breed a bad name.’’ “Bull calves that are just born too big and then take two years to look good after being pumped full of feed, or have these fantastic figures but just don’t reflect those figures themselves. We like our calves to be good all the way, especially by 10-15 months off grass, as this is the age our clients will mostly be wanting to sell their calves by.’’ Graeme said he was particularly concerned about the structural soundness of some of the young US sires hitting the market (see Talking Points this page). THE NEED FOR MULTI-BREED EBVS OR BETTER EDUCATION THE COMMERCIAL CONNECTION Rangan Charolais has achieved impressive brand recognition in the southern cattle industry – in fact Graeme rates it as probably their biggest achievement to date. He links it to their commercial operation, with farmers able to see first-hand the potential benefits of using a Charolais over British cows. Several clients in north-east Victoria have also won prizes or topped store markets with Charolais-cross calves, adding to the recognition of Rangan Park bulls. “Our commercial operation really compliments our stud,’’ Graeme said. “I don’t think we have a neighbor now who isn’t using our bulls and that is because they have looked over the fence and admired our crossbred calves.’’ Graeme said they also worked closely with clients to help achieve a good result. This involved taking into account what type of female herd people were running, and if the calves were to be sold directly off cows or grass and grain finished. “An F1 cow (Friesian/beef cross) can handle a heavier muscled, heavier boned and leaner bull as they have the milk to finish the resulting calf,’’ he said: “A straight bred beef female needs a bull with a bit of extra fat cover and less bone so the progeny can be finished easily by 12-15 months of age.’’ The Cooks also present a very professional front to perspective buyers, wearing branded uniforms at sales and industry events, and having a polished website with professionally taken photos of both their stud and commercial cattle. This year they plan to use their website to promote Rangan Park sired calves for clients. “To grow the business I have to take market share from some-one else, and for us that’s mostly from another breed, usually the Angus or Limousin,’’ Graeme said. “To do this you have to be passionate about what you are trying to achieve and you have to give your clients value.’’ n “BREEDPLAN is a great marketing tool. But a lot of our clients, and prospective clients, have been using Angus, and they are used to numbers like +70 for 400 day weight, and +3.5 for EMA, so they are not that keen on purchasing a Charolais with a breed average of +17 and EMA of +1.3. There is no correlation between the Angus and Charolais BREEDPLANS, but people don’t understand and I’ve lost count of the times I’ve had to try and explain this. The sooner we have multi-breed EBVs the better, but I’m not sure the Angus as a breed will ever let this advantage go. Maybe better education is the key.’’ THE CHAROLAIS BIN PROJECT “I was disappointed in the initial Charolais Society sponsored BIN progeny test program run in Victoria in 2009/2010. The bulls represented were a number of Charolais and one Limousin. I don’t know how they thought they were going to get meaningful information for the marketplace when they did not include the biggest breed in southern Australia – Angus. A properly constructed progeny test that included a number of high accuracy Charolais and Angus bulls, both joined to Angus females with the calves carried all the way through to slaughter, could well have given us the marketing edge I believe the Charolais has, but which as a breed we need to prove conclusively. Either way, lets find out.’’ SALE CREDITS “Sale credits operating in stud sales should be announced before the start of the sale, and they should be subtracted from the gross and average, as they give a false high to the sale. If no bull sale credits are operating, state that fact.’’ CHAROLAIS MAGAZINE > www.charolais.com.au 39 Joyce Muller with the family's first draft of Charolais Roan-cross vealer calves for 2012, which were sold at the Shepparton prime market in early November. Low cost approach to production pays off! By Jenny Kelly Fred and Joyce Muller haven’t been the type of farmers to chase trends on their Victorian grazing property at Nagambie. Indeed Fred is quite proud of their conservative and low-cost approach to production. “We’ve never sown anything down and we’ve never put super on,’’ he said of their 1,100 acre dryland farm which is used mainly to run cattle, with smaller sidelines of cropping and first-cross ewes for prime lambs. “And all our machinery would be 30-years old except for our tractor – why change something if it still works ’’ So the fact they have moved to using Charolais bulls over their entire herd of 140 Roan (Shorthorn Hereford-cross) and Hereford cows speaks volumes for their performance. 40 CHAROLAIS MAGAZINE > SUMMER 2012/2013 “I like money too, and the Charolais-cross calves sell better than all the others. They weigh better and the buyers like them,’’ Fred said. Although in standard Muller style, they only dipped their toe in when first contemplating a move to a terminal European bull. They borrowed a Charolais sire about five years ago to join to a few cows. “We never rush in – we always have a look and see how it goes,’’ he said. “But we just loved the calves, we’d never had vealers weigh in the high 300kg to 400kg before and we’d tried a lot of breeds – Angus and Santa Gertrudis among them.’’ While the Mullers are conservative, they do have a passion for quality cattle and are prepared to spend on their favoured breeding cow, the roan Shorthorn Hereford-cross, which only rarely appear in saleyards. Joyce said they were an easy care beef cow with good milking ability and a sound temperament. “We’ve always had them and have become a big fan, especially of their milking ability,’’ she said. “When roans are advertised at markets we usually go and it is not often that we are beaten.’’ The Roan cows, Fred said, also offered a marketing edge as they were an unusual item and their Charolais-cross calves, which often carried the same distinctive colored markings, could be sold as either stores or for slaughter. “We’ve only had to pull a couple of breech births with the Charolais, but I don’t know how many calves we’ve had to pull out of PTIC cows we’ve bought-in and which were supposedly joined to low-birth weight British bulls,’’ he said. Cross into Profit The Muller's use Kenmere Charolais bulls from NSW across their Roan and Hereford cow herd based at Nagambie in Victoria. Last year the Mullers averaged 234 cents per kilogram for their complete drop of Charolais-cross steer and heifer vealers which weighed an average of 355kg liveweight, returning $834 a head. When the Charolais Magazine visited the Mullers in early November they had just begun to draft and sell this season’s drop of calves. The Mullers have concentrated on the vealer market, joining the cows in April for a mid January calving so the calves can benefit from a full spring before being sold in drafts at the weekly Shepparton prime cattle market. So far they had received a top of 248c/kg for steers, but with the southern beef market contracting as the dry season hit, prices had fallen away each week. They have four Kenmere Charolais bulls, bred by Matthew and Anne Marie Collins at Cobbity in NSW. The draft of 21 calves pictured with Joyce sold to a top of 212c/kg, with some unusually severe discounting appearing for heifers in the marketplace. Fred said they looked for muscling, frame and conformation in the bulls they selected, and had been impressed by the Collin’s family follow-up support and interest in their breeding operation. “Our calves are still towards the top price of the market, but it has been a pretty poor market, particularly for vealer heifers this year,’’ Fred said. n He said, from their experience, concerns about calving problems with Charolais bulls were over-hyped.
