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.

Cattle Handling and Care Certification

Coordinate the Cattle Handling and Care program. Developed a video, chute-side aid and assessment exam.  This program encourages the best management practices in the proper treatment of cattle.  Participants that complete the program and pass the proficiency exam receive a barn sign designating their certification. 

Master Cattleman Program

Develop and present educational materials on beef breeding management. This is a four hour course that covers assessment, crossbreeding and selection.

Beef Genetic Improvement Program

Developed a bull selection process for beef producers to qualify for cost-share dollars from the Kentucky Ag Development Fund.  The process involves an educational program on matching genetics to management and crossbreeding, the producer identifies the category of bull that best fits their situation and then purchases a bull that meets the Expected Progeny Differences guidelines within that category.
