In a recent Oklahoma State University study, researchers explored the use of genetic market panels to help improve profitability at the cattle feedlots.
Drovers CattleNetwork reports the study used data from 5,353 feedlot cattle from six feedlots. At placement, the animals were weighed and a hair sample or tissue punch from ear tag application was collected for genetic testing.
According to the study, molecular breeding values (MBVs) characterizing average daily gain, hot carcass weight, yield grade, rib-eye area, marbling, tenderness and days-on-feed were provided. The study’s authors say that while Expected Progeny Differences (EPDs) represent the genetic potential of an animal as a parent, MBVs represent the genetic potential of an animal to express a given trait; with increases in MBVs it is likely to improve more favorable outcomes.
“As genomic testing technology continues to advance, the potential for declining costs of genetic testing and the development of markets for other important feedlot profit drivers, such as disease resistance and feed efficiency, may lead to cost-effective marker-assisted management in the feedlot sector,” the authors conclude.
