Sequenced the genome of two influential bulls

Sequencing the genome of these two bulls enables scientists to more accurately identify the genetic markers that are responsible for economically important traits such as efficiency, yield, fatness and tenderness, say the scientists. Producers can use that information to breed healthier dairy cattle that produce more and higher quality milk as well as beef cattle that produce better quality beef.

The animals used in the project have had a high impact on the breeding and commercial sectors in dairy and beef. The dairy bull was sequenced in collaboration with Semex Alliance, a Canadian dairy bull breeding company that owns and samples 450 dairy bulls per year globally and marketed over 7.5 million doses of semen in 2007.

There will also be benefits for the beef industry. Better knowledge of the genetic variation across the breeds will, through better breeding decisions, improve production efficiency, product quality and animal health, and reduce the environmental footprint of beef cattle production.
