Research & Extension Interests:
- Feed efficiency in beef cattle-Quantitative and
molecular analysis of the genes that affect feed efficiency.
- Use integrated beef cattle systems to reduce
variation in feeder and stocker cattle.
- Whole herd reporting, integrated resource management (IRM), and
standardized production analysis (SPA).
- Compare cattle produced through AI coupled with estrus
synchronizations to cattle produced in conventional methods.
- Compare cattle of known genetic background to cattle of unknown
genetic background from the start to finish of the production chain.
- Develop methods of predicting feedlot performance using different
systems of production.
- Investigate different systems of cross breeding to determine optimum
levels of performance in cattle of various crosses and identify markets
for each class of crossbred cattle.
- Work to determine the value of cattle when the total system of
production is considered. Economic analysis to determine optimum
production from conception to consumer.
- Develop optimum harvest endpoints for different
biological types of cattle under different production scenarios and
marketing alternatives.
- Work with all segments of the beef industry to
integrate data collection and analysis enabling beef producers to
monitor cattle through the production system from point of origin to
endpoint use identifying where beef quality defects occur and implement
corrective measure to ensure food safety.
- Investigate phenotypic and genetic correlations
between tenderness as predicted by the Hunterlab BeefCAM, Warner-Bratzler
shear force, taste sensory panels and overall tenderness panels.
Determine heritability estimates for tenderness using the Hunter Beef
Cam scores and scan the genome to determine if QTL's are present.
