Penn State Extension expert sees beef quality continuing to improve
March 12, 2018
UNIVERSITY PARK, Pa. — Following 25 years of measurement, management and continued improvement, the quality of beef is high, but there is still an opportunity to make it better, according to a beef cattle specialist with Penn State Extension.
The most recently completed National Beef Quality Audit tells us we're doing a good job implementing change to improve production shortfalls, said Dan Kniffen, assistant professor of animal science, who recently served as chairman of the National Beef Quality Assurance Advisory Board. However, in a dynamic system such as beef production, there is always room to make it a little better, he said.
"The beef industry quality audit encompassed both fed cattle and market cows and bulls, and researchers from eight universities were involved in the project," Kniffen said. "Texas A&M, Colorado State and Oklahoma State universities took the lead in gathering data and interpreting the results for cattle producers."
Market breeding stock that includes dairy animals contributes a significant volume of beef for the world market, Kniffen said. These market animals can also contribute up to 20 percent of revenue into the business and these market animals present virtually no additional expense.
The initial checkoff-funded Beef Quality audit was conducted in 1991. The first audit focused on finished cattle. The Beef Quality effort evaluating market cows and bulls was first initiated in 1994. Since the first cow and bull audit, the industry has made significant strides in five major categories: herd management techniques, animal welfare and handling, hide damage, injection-site damage, and location and carcass bruising.
The initial directives to the industry helped producers focus on specific areas for improvement. Those instructions stated that if the industry would work to make the following improvements it would significantly enhance the value of market animals: Recognize and optimize the value of market cows and bulls on the farm or ranch; be proactive to ensure the safety and integrity of the beef product; closely monitor herd-health issues and market cattle appropriately and in a timely fashion; and use appropriate management and handling techniques to significantly reduce or prevent carcass-quality defects. "The industry made progress. By the time of the second audit in 1999, the industry had made significant strides in reducing condemnations, the frequency of disabled cattle, bruising, damage caused by branding, injection-site lesions and improving the overall condition of cattle," Kniffen said.

"Reduced numbers of injection site lesions through the years is one of the industry's true success stories. Additional research conducted in 2017 evaluated the presence of injection-site lesions in the round based on the same procedure used in previous injection-site audits. That research demonstrated a 20 percent reduction in lesions during the past 15 years in dairy-type carcasses."
But the industry was not finished, Kniffen pointed out. The most recent 2016 audit identified good progress in managing these issues and suggested improvements for further increasing the value and marketability of cows and bulls. Over the life of the audit, food safety, as a quality attribute, has grown into one of the most important factors for those who purchase wholesale beef.
Cattle transportation and mobility for all cattle types was surprisingly good. Most cattle walked normally with no apparent lameness. This compared favorably with results from previous cow and bull audits. Since 2007, there has been an impressive 24.6 percent increase in dairy cow mobility. This measurement indicates that the industry's dairy animals are walking better.
Producers must continue to embrace this positive finding, Kniffen said. "Timely marketing is the most important factor to sustain this positive trend. The industry must continue to take advantage of proactive marketing of cows before lameness is observed or becomes an issue."
A portion of the audit included live-animal evaluations. Since 2007, there has been a trend toward increased body condition scores in both beef and dairy cows. There was a 36 percent increase in the body condition score of 3 or above (scale of 1-5) to 45 percent in 2016.
One problem pointed out by the audit — more than half of cow carcasses examined were bruised, which is an increase compared to 2007. The majority of the bruises were of minimal severity, requiring less than 1 pound of surface trim to remove the damage. Most of the bruises in cows were located in the round or sirloin.
"There is still plenty of opportunity to improve this handling defect — reducing the prevalence of carcass bruising, particularly in dairy cows, needs to be a higher priority for both cattle handlers and transporters," Kniffen said. "This simple change will help to improve the carcass values of all market cattle."
The take-home message for both beef and for dairy producers is there are dollars left on the table by the industry when it comes to maximizing the carcass value for market animals, Kniffen said.
Progress can continue, he said, if the industry will focus on: food safety, appropriate management of market cows and bulls to increase muscling (weight) before harvest; timely marketing before physical defects become severe; gaining a better understanding of the causes to eliminate carcass bruising; reducing defects to allow the cow and bull industry to capture additional value; through the use of Beef Quality Assurance programs to propel the momentum of the cow and bull industry forward.
