CURRENT PROGRAM EMPHASIS

Beef Cattle Breeding Management

Providing Kentucky’s beef producers with the necessary tools to maximize profits from their operation. The primary focus is to encourage sound crossbreeding programs to take advantage of heterosis and educate producers on the use of Expected Progeny Differences in their selection practices.

Beef Integrated Resource Management (IRM)

Member of the multi-discipline coordinating committee that oversees the statewide IRM program. The effort of the beef IRM coordinating committee is to implement a state-wide educational program based on integrated concepts. The overall goal of the committee is for Specialists, Ag Agents and ultimately producer to apply holistic concepts to management and problem solving, based on predetermined goals.
