Effects of reduced metabolizable protein diets supplemented with rumen-protected His under adequate Met and Lys supply on production, nutrient digestibility, N utilization, and manure ammonia emissions in lactating cows
ABSTRACT: Balancing for limiting AA may prevent reduced production when deficient MP is provided. The objective of the study was to determine the effects of rumen-protected (RP) His supplementation at different levels of MP when Lys and Met supplies meet the requirements. Sixty lactating cows (mean...
