ABBA Announces Results of Carcass Evaluation Program
T
HE AMERICAN BRAHMAN BREEDERS ASSOCIATION (ABBA) announced the results of the ABBA carcass evalu-
ation program in February. The program consisted of 75 head of registered
Brahman steers representing 8 ranchers from Arizona, Louisiana and Texas. The spring 2013 steers were delivered to Graham
Land & Cattle Company, Gonzales, where they were fed for an average of 204 days prior to being harvested. The steers were harvested at Kane Beef, Corpus
Christi, with Dr. Joe Paschal of Texas A&M University AgriLife Extension collecting the carcass data and compiling the results. The data was provided to the participants and incorporated in the ABBA’s genetic evaluation for the calculation of expected progeny differences (EPDs). The steers were indexed based on average daily gain, rib eye area, marbling score and Warner-Bratzler shear force score for tender-

ness. The top indexing steers and top sire groups were identifi ed. The cattle did well in the feedyard, gaining 2.52
pounds per day. The group produced an average USDA Quality grade of High Select, and a yield grade of 3. The carcasses had a Warner-Bratzler shear force of 6.06 pounds, well below the industry threshold. J.D. Hudgins-Locke Division, Hungerford, owned
the top indexing steer. V8 Ranch, Hungerford, owned the top indexing sire group by Mr. V8 463/6. The ABBA Carcass Evaluation Program is one of the most exten- sive carcass data collection programs in the country. Since 2001, more than 1,400 steers representing more than 300 sires have been put through the program by their owners, making ABBA one of the early beef breed associations to launch carcass EPDs, the second breed association to launch a tenderness EPD, and the fi rst to launch a marker-assisted EPD for tenderness.
