Typically associated with seedstock cattle evaluation, genetic profiling for specific production traits may have future applications within the stocker segment, according to Justin Rhinehart, beef cattle specialist for
Rhinehart says that as the technology continues to expand and become more widely available, he views obtaining information on individual calves (versus dam and sire information) as a more valuable opportunity. If the technology proves to be cost-effective, Rhinehart believes that stocker operators may be able to sort cattle based on their individual performance potential as determined through the DNA-based technologies. “A sorting or marketing plan should be developed that will capture full benefit of the tool,” Rhinehart says. “For example, sorting the group according to feed efficiency predictions could allow for tailored supplementation.
“Regardless of whether stocker operators choose to incorporate DNA-based technologies to reach their production goals, a working knowledge of the basic principles will be important as it becomes more widely used in other sectors of the industry,” Rhinehart adds.
