Research Interests

• Factors affecting intake and utilization of grazed and harvested forages by beef cattle - including effects of forage species and maturity, harvesting and/or processing methods, supplementation with high fiber or by-product concentrates, and forage combinations on digestive kinetics, nutrient flow, microbial colonization and fermentation, particle size reduction, intake and animal performance.
• Nutritive value of barley varieties in diets for feedlot cattle.
• Development of nutritional programs for wintering beef cows.

Accomplishments and Interests

• Identified QTLs for ruminal digestibility and particle size on barley chromosomes 3 & 4.
• Determined heritability of digestibility in barley to be 50%.
• Demonstrated legume supplementation of low-=quality forage diets increases rate of large particle size reduction and passage from rumen, allowing increased intake by cattle.
• Demonstrated ruminal carboxymehthylcellulase activity can be used to compare relative colonization and activity by cellulolytic bacteria.
• Demonstrated differences in rate and pattern of ruminal bacterial colonization of cool-season grasses, warm-season grasses and legumes, and relationship to fiber digestion.
• Established that a barley variety with extremely rapid ruminal digestion could support superior feedlot performance, indicating rapid ruminal digestion is not strictly a negative influence on animal performance.
