Comprised of 6 one hour presentations delivered via the internet during August and September, the webinar course was facilitated by staff from Southern Beef Technology Services (SBTS) & Tropical Beef Technology Services (TBTS), and presented by senior beef industry scientists from the Beef CRC. The webinar course was well attended with a total audience of over 500 people and 250 individual seedstock enterprises.
The topics presented during the webinar course included:
- Genetics for Reproduction – The Female Influence
- Genetics for Reproduction – The Male Influence
- Relationship between Body Composition and Calving Rate
- Effect of Genetic Differences in Fat and Net Feed Intake on Efficiency of Weaner Production
- The Beef CRC DNA test for Growth, Feed Efficiency, Carcase and Reproductive Performance
- The Australian DNA Test for the Polled Gene
All presentations in the “The Cutting Edge” webinar course can now be viewed from the webinars page on the SBTS (http://sbts.une.edu.au) and TBTS (http://tbts.une.edu.au) websites.

FOR stud breeder Peter Sykes, a genetic test to see if his sires will produce polled progeny is another piece of valuable information.
Peter and his wife Deanne run the Mawarra Hereford stud at Longford and for the first time they have DNA tested their sale bulls for genetic poll information.
Producers were told about the test, which has only been commercially available for 12 months, at a Hereford field day at Mawarra earlier this month.
The DNA test was developed by the Beef Co-operative Research Centre, CSIRO, Meat and Livestock Australia and University of New England in response to industry concerns about dehorning and animal welfare.
Pfizer Animal Health has commercial rights to the genetic test which retail for about $25 and, according to company sales representative Jeffrey Doolan, requires 20 to 30 hair tail samples.
“The polled gene is a single gene trait (and) it’s a dominant gene whereas horned (trait) is a recessive gene,” Jeffrey said.
He said the test identifies the probability of an animal being homozygous polled, which means it carries two copies of polled variant gene, or heterozygous where it has both the polled and horned gene.
According to Jeffrey, testing in Herefords has shown results are about 99 per cent accurate, while Beef CRC research says it’s also highly accurate for Brahman, but some British and European breeds are more ambiguous.
