Ranchers Learn About the Injection-Site Blemishes, Value of Beef Carcass
By Blair Fannin
A team of Texas A&M AgriLife Extension Service specialists demonstrated how much injection–site blemishes can diminish the value of high-end cuts from the beef carcass at the recent Texas and Southwestern Cattle Raisers Association Convention in Fort Worth.
Dr. Joe Paschal, AgriLife Extension livestock specialist from Corpus Christi, was joined by Dr. Dan Hale, AgriLife Extension meat specialist, and Dr. Tom Hairgrove, AgriLife Extension beef cattle veterinarian and food animal specialist, both from College Station, who gave a demonstration on the value of proper injection sites on cattle.
“We wanted to give beef cattle producers an overall perspective of injection sites and show them just what injection-site blemishes do in reducing the value and acceptability of the high-value cuts,” Paschal said.
Paschal said since the initial National Beef Quality Audit in 1991, injection–site  blemishes are still in the top 10 quality challenges and cause substantial loss of product, although progress has been made in reducing their impact.
The demonstration included injection-site samples of blemished cuts of beef round and sirloin as well as how to identify proper injection sites in the neck region. Though sometimes overlooked, proper placement of animal health product in the neck region can help preserve value on down the production chain, according to the experts.
“When we move those injections to the neck area, we reduce damage to some of these high-value products and don’t hurt the value of the carcass nearly as much,” Paschal said. “Injections given in the muscle, deep inside the round and sirloin, those are high-dollar cuts relative to a muscle we find in the neck. That’s the whole purpose of the exercise, to try to minimize the reduction in value to those cuts.”
Hale said many years ago ranchers were giving animal health product injections in the hindquarters of the animal.
“However, over the last 15 years we’ve seen a lot of producers moving to the neck area,” he said. “We move it there to keep animal health product and injection blemish in the neck so it’s not in a high-price meat cut item. It’s a very effective way to put the animal health product in that location for record keeping and to make sure withdrawal times are properly followed before that animal leaves the premises.”
