International Collaboration on Economically Relevant Traits

During the 2009 Beef Improvement Federation (BIF) symposium, U.S. Meat Animal Research Center (USMARC) geneticist Gary Bennett reported that collaborators from Australia, Canada and the United States are attempting to maximize use of high-density single nucleotide polymorphism (SNP) information by combining their research results.

Bennett said each collaborator has a large group of animals that have been genotyped for approximately 50,000 SNPs. In addition considerable phenotypic information is available for weights, carcass measurements and feed intake. Each collaborator is analyzing their own data, but sharing the results.

“Comparing these results across the different environments and germplasm represented in the collaboration should offer better estimates of their reliability,” Bennett predicted.

Opportunities to expand the collaboration to other public and private groups having genotypes and phenotypes is being pursued with the intent of further testing the reliability of SNP associations with weight, carcass and feed intake traits, and expanding the effort to female reproductive traits.
