Interactions of exogenous protease and phytase (PP) and direct-fed microbial (DFM) on apparent ileal digestibility coefficient^†.

a,bLeast square means in the same column without a common superscript differ significantly, P≤0.05. n = 8 samples per treatment for interactions. 1Formulated to meet breeder requirements for 14–21 d old broiler chicks except with a reduction of 0.94 MJ/kg of ME. 2Crude protein. †Determined in broiler chickens at 21 days of age in Experiment 1.
