Short communication: Effect of carbohydrate fermentation rate on estimates of mass fermented and milk response

Abstract

Current prediction equations were used to evaluate the effects of rates of fermentation of fiber or starch in individual feeds on amounts of carbohydrate fermented ruminally and milk yield responses. The small predicted increases in carbohydrate fermented and milk response associated with doubling the rates of fermentation suggest that current prediction equations are relatively insensitive to changes in rate of fermentation.
