Effect of ensiled alpha-amylase–enabled corn grain at 2 concentrations in the diet on lactation performance, chewing activity, ruminal fermentation, nutrient digestibility, and nitrogen partition of dairy cows

Effect of ensiled alpha-amylase–enabled corn grain at 2 concentrations in the diet on lactation performance, chewing activity, ruminal fermentation, nutrient digestibility, and nitrogen partition of dairy cows

ABSTRACT: This experiment evaluated the effect of α-amylase–enabled corn (AAC) on cows fed ensiled mature kernels at 2 concentrations in the diet. Twenty individually housed Holstein cows, arranged in 4 × 4 Latin squares (with 21-d periods), were exposed to each of 4 treatments in a 2 × 2 factorial...
