Newsletter Grab from ADHIS (the Australian Dairy Herd Improvement Scheme) For immediate release: 18 August 2013 Two newsletter grabs: Genomics tops dairy talent (350 words) Latest update to your herd’s genetic trends (160 words) Genomics tops dairy talent Genomic bulls dominate the top bulls in the latest list of Australian Breeding Values (ABVs) released by the Australian Dairy Herd Improvement Scheme (ADHIS) this week (August 19). Michelle Axford from ADHIS said that more than half the Holstein bulls in the latest Good Bulls Guide (which lists the top dairy bulls) were young genomic bulls. “Genomic – or DNA – testing is having a major impact on dairy artificial breeding in the two years since the technology was introduced in Australia.” “Three years ago, there were no genomic bulls in the Good Bulls Guide. Two years ago less than 25% of the Holstein bulls in the Guide were young genomic bulls. That represents a rapid uptake of the technology,” Mrs Axford said. She said the rapid uptake was because genomic testing could be done when an animal was any age, so breeding values could be estimated for young cows and bulls, long before performance data was available (or daughter performance data in the case of bulls). “This means bulls can be used with confidence from a much younger age, and that will contribute to a faster rate of genetic gain in Australia’s dairy herds.” The Good Bulls Guide includes 22 proven bulls that have returned to service having previously been available on the market as young genomic bulls. “The farmers who used these bulls as young genomic bulls will now be joining their heifers. That’s a full two years earlier than before this technology was available,” she said. Genomic testing is also useful for older animals, even proven bulls with daughter performance data. “Bulls proven overseas without any Australian daughters have more reliable breeding values with the addition of genomics. The reliability of Australian proven bulls improves, particularly for hard to measure traits such as fertility,” she said. “Seventy one per cent of the Holstein bulls listed in the guide have been genotyped, which illustrates how valuable the information is to the artificial breeding industry.” The Good Bulls Guide is posted to dairy farmers or can be downloaded from www.adhis.com.au from 19 August.

Michelle Axford from the Australian Dairy Herd Improvement Scheme (ADHIS) said many dairy farmers had received Genetic Progress Reports since they were first released earlier this year and they would be keen to see any changes in their latest reports. “Anyone who herd records can get a Genetic Progress Report through their herd test centre. It is a simple way to see the impact of breeding decisions and benchmark your herd against the national herd.” “Use your herd’s Genetic Progress Report to identify breeding priorities and the Good Bulls Guide to make bull choices. Both are updated twice a year with the ABV release,” she said. Sophie Hester from Larpent in Western Victoria said “it is interesting to see the impact of bull decisions on the herd’s genetic merit for specific traits.” For more information contact Michelle Axford at ADHIS ph (03) 8621-4240 or email maxford@adhis.com.au.
