Extract

Enhanced cellulolytic activity in the rumen and improved balance between amino acids and energy have been suggested to increase silage dry matter intake in cows given high quality protein supplements. The objective of this study was to investigate the effects of casein infused continuously into the rumen, duodenum or both on forage intake, milk yield, milk composition and microbial protein production.
