  • Using yeast-based and non-antibiotic additives to feedlot cattle.
  • Performance, rumination, and rumen pH responses to different dietary energy density and feed management strategies in auction derived feedlot cattle
  • Feeding agricultural byproducts and corn stalks to feedlot cattle
  • Energy requirements of indicus × B. taurus cattle
  • Energy requirements of indicus × B. taurus cattle
  • Antimicrobial additive affected by ruminal microbiome, differences between cattle subspecies
