Abstract:
Exogenous amylase, sucrose, or a combination was used in diets with reduced starch content.
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.
