My research is focused on improving forage management and supplementation strategies in beef cattle operations in the Southeast US. Extending the grazing season, animal nutrient use efficiency, and strategies to enhance forage contributions in beef cattle systems in the region are priority areas of focus for my integrated research/extension program.


The Alabama Beef Systems Extension Program provides research-based beef cattle management systems recommendations to producers to enhance on-farm efficiency and sustainability in the Southeast U.S. Our program focuses on the development and delivery of educational programs and demonstrations with stakeholders to improve knowledge, awareness and adoption of best management practices related to forages and nutrition in beef cattle operations.
