The trial was performed in 48 lactating Holstein cows, and milk yield, milk composition, and dry matter intake were measured. Treatments did not affect production traits, but with slightly decreased feed intake and slightly greater milk production in amylase-fed cows, the calculated value of amylase in this study was $0.37/cow per day.DairyEnzymeMilk productionNutritionFeed intakeConference paper
