†CON and CDFM diets differed only by the inclusion of DFM at 0.05 g/kg or 1.48 × 108 CFU/g of complete feed.
‡CDFM (United Animal Health, Sheridan, IN) had a guaranteed count of 1.48 × 108 CFU/g and was included at a rate of 0.5 g/kg of feed to provide a final count of at least 7.35 × 104 CFU/g of complete feed.
||Diets were calculated based on Metabolizable energy (ME), standardized ileal digestible (SID) amino acids, and standardized total tract digestible (STTD) phosphorus.
