The American Gelbvieh Association (AGA) has released to its members the results of DNA marker testing on its top 25 most-used sires. The testing program is part of AGA's Carcass, Ultrasound and Tenderness (CUT) initiative. Its aim is to utilize traditional carcass testing, ultrasound scan results and DNA markers to evaluate an animal's genetic potential in regard to carcass traits.
The only U.S. breed association providing this data on the most influential sires within the breed, AGA says its not advocating single-trait selection but offering a tool to allow members to make the sire-selection decisions most appropriate for their specific production environment.
Tenderness-marker data on the Top 25 A.I. sires in the Gelbvieh breed, along with discussion of the DNA tenderness markers, is available at www.gelbvieh.org. Contact AGA at 303-465-2333 or firstname.lastname@example.org.
