Research Interests
- Incorporating sheep into sustainable crop production systems for insect and weed pest control, and residue management.
- Nutritional and management factors that improve sheep production efficiency.
Accomplishments and Interests
- Investigate alternatives to traditional crop residue and fallow management using sheep to control weed and insect pests and enhance soil nutrient cycling.
- Develop strategic nutritional intervention strategies for the late gestating ewe to minimize neonatal losses by improving lamb immune function and/or fetal and neonate energetic status.
- Determine profitable management options that enhance quality and expand the availability of market ready lean lamb beyond current seasonal limits.
- Develop and maintain online programs to aid students and producers in making sound nutrition and management decisions.
