Feeding amylolytic and fibrolytic exogenous enzymes in feedlot diets: effects on ruminal parameters, nitrogen balance and microbial diversity of Nellore cattle

Feeding amylolytic and fibrolytic exogenous enzymes in feedlot diets: effects on ruminal parameters, nitrogen balance and microbial diversity of Nellore cattle

Abstract Background The environmental impact of feedlot operations is a growing concern, as cattle excrete a significant portion of feed nutrients as waste. Exogenous feed enzymes (EFE) have gained interest for their potential to enhance feed efficiency in ruminants by improving nutrient digestion....
