- Differences between Rambouillet and Dorper ewe performance and metabolic indices during pregnancy in an extensive grazing system. 2005 to 2007 (with D. F. Waldron).
- Effects of CP supplementation on performance, rumen microbial activity, feed selection, mohair growth and quality. and carcass characteristics of goats. 2006 to present (with C. J. Lupton).
- Enhancing NIR prediction equations for juniper and CP intake in small ruminants. 2006 to present (with J. W. Walker).
- Enhancing NIR prediction equations for feedstuff CP. 2008 to present (with C. J. Lupton).
- Effects of Juniperus pinchotii Sudw. (redberry juniper) terpenes and leaves on fiber and carcass characteristics, and animal performance. 2007 to present (with C. J. Lupton, et al.).
- Effects of Juniperus pinchotii Sudw. (redberry juniper) terpenes and leaves on in vitro dry matter and nutrient digestibility. 2007 to present.
- Effects of Juniperus pinchotii Sudw. (redberry juniper) terpenes and leaves on reducing internal parasites. 2007 to present (with T. Craig).
- Evaluating the use of Juniperus pinchotii Sudw. (redberry juniper) as a roughage source in lamb and goat feedlot rations (with C. J. Lupton, et al.).
- Evaluation of the nutritional and feeding value of ethanol by-products for small ruminants. 2007 to present (with C. J. Lupton, et al.).
- Evaluating the use of Juniperus pinchotii Sudw. (redberry juniper) and DDG as a winter supplement for sheep and goats.
- Evaluating the use of Juniperus pinchotii Sudw. (redberry juniper) and DDG as a deer supplement. (with Suzan Cooper and Butch Taylor).
- Evaluation of the roughage level needed in lamb feedlot rations when they contain DDG. 2007 to present (with C. J. Lupton, et al.).
- Evaluating the technological and economical aspects of harvesting juniper to be used as a feedstuff.
- Enhancing new laboratory methods: a) evaluate effects of adding urea to an in vitro rumen buffer solution on in vitro dry matter and crude protein digestibilities of low quality feeds and effects on rumen pH and ammonia N; b) determine more effective and efficient ways to quantify bacterial contamination (particle-associated bacteria) of feedstuffs incubated in rumen fluid to reduce errors currently associated with determining CP digestibility; and c) improve a larvae migration inhibition assay method to determine internal parasite viability.
