Calf Preconditioning: A Comprehensive Overview

By Paul Vining, Paul Beck, Kellie Curry Raper, David Lalman, Blake Wilson, Rosslyn Biggs and Darrell Peel. Learn about health and economic benefits of beef calf preconditioning practices. "Preconditioning" in the beef industry involves management practices designed to bolster calf immunity and nutritional health while minimizing stress-related challenges during marketing and transport. Preconditioning prepares calves to manage subsequent stages of the beef supply chain, resulting in higher calf value due to reduced illness rates. These practices not only lower medical and labor costs associated with treating sick calves but also enhance overall economic viability within the beef industry.
