Research Interests

• Forage Crop Production.
• Management and harvest strategies for pasture and hay crops.
• Emphasis is on optimizing production of protein and digestible nutrients per acre of Montana's forage crops.
• Current investigations include plant maturity effects on alfalfa and grass quality and minimizing bloat risk of alfalfa-based pastures.

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.
