Research Interests
Areas of research interest focus on pre- and post-harvest methodologies that impact factors considered traits of value to the red meat industry and red meat animal producers. Current programs of interest include:
- Pre-harvest production and management factors that affect lean meat yield, quality and profitability for beef and pork
- The use of novel feed stuffs on animal performance, red meat yield, quality, composition, tenderness and shelf-life
- Identifying methods to increase the value of red meat products through muscle profiling
- Genetic and environmental differences that influence the rate of lean development and deposition as influenced by the autocrine, paracrine and endocrine systems
- Investigation of pre- and post-harvest food safety strategies
Courses Taught
