Research Interests

  • Variation in individual animal consumption of supplement.
  • Effect of supplement delivery method (hand-fed vs. self-fed) on individual supplement consumption.
  • Supplementation of beef cattle consuming forage diets.
  • Nutritive value of barley varieties in diets for feedlot cattle.
  • Development of nutritional programs for wintering beef cows.

Accomplishments and Awards

  • 2005 - MSU Cox Family Fund for Excellence Faculty Award for Creative Scholarship and Teaching
  • 2004 - Western Section American Society of Animal Science Distinguished Teaching Award
  • 2001 - MSU College of Agriculture Outstanding Professor Award
  • 1997 - Western Section American Society of Animal Science Young Scientist Award
  • Developed 2 new courses:  ANSC 418-Topics in Beef Cattle Nutrition, and EQUS 423-Equine Nutrition.
  • Developed prediction equations for NEm and NEg of barley grain based on laboratory measurements.
  • Using gene mapping techniques, identified molecular markers in barley that affect feed quality, allowing for genetic marker-assisted selection of improved feed quality barleys.
  • Determined liquid supplement (30% CP) provided to cows grazing native range in winter, increased forage digestion and intake, resulting in less body condition loss.
  • Determined liquid supplement consumption by individual cows grazing native range varied widely, with a CV of 70 to 125%.
  • Determined that increasing the level of starch in supplements fed to beef cows grazing native range in the winter, decreased forage digestibility and intake.
  • 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.
