The Effect Of Amylase Supplementation With Low-Starch Rations: Effects On Milk Production And Feed Consumption, Alfred Eaton

Dairy Science

The objective of this trial was to determine if there was an increase in milk production or a decrease in feed consumption by dairy cattle when fed an exogenous rumen-resistant amylase, named RumiStar. High feed prices have caused dairymen to look for new ways to be more efficient. Commercial feed additives have been proposed as opportunities to improve efficiency. In our study a minimum of eighty multiparous Holstein cows were assigned to each of two pens, with a minimum of forty cows in each.
