The Beef Podcast Show
Genetic Selection and Limitations in the Beef Industry
The adoption of genetic selection in the American Angus industry has significantly increased average daily gain in beef animals over the years. Selective breeding has not only focused on growth but likely improved nutrient digestibility and absorption as well. The advancement in genetics, animal husbandry, housing, and technologies like implants and beta agonists have led to more efficient beef production. However, there is a growing concern in the industry about potential biological limits due to continuous genetic enhancements. There is a need to balance genetic improvements with factors like animal health as exceeding certain thresholds may lead to compromises. Precision agriculture could play a crucial role in managing cattle by effectively matching genetics with nutrition and marketing strategies. Programs like Angus Link, with a genetic merit scorecard, aim to enhance the management of feeder cattle by characterizing their genetic potential for growth and grade. It is anticipated that advancements in understanding genetic differences and better management practices will shape the beef industry positively in the coming decades.
