Extension program focus is on improving beef cattle productivity and profitability through advances in nutritional management. Emphasis is on improving forage utilization and strategic supplementation of forages. An additional interest is focusing on using web based technology as a component in educational programming. Current use includes web based monthly meetings (Beef Forums) with extension agents with plans to expand to web based educational programs targeted at cattlemen.

Research interests include forage, nutritional and management options for cattlemen and the impact on the sustainability and profitability of beef cattle production.
