Each mean represents 6 pens with 5 pigs each per treatment. Dietary treatments were as follows: NC = Negative control diet; PC = Positive control diet with 40 mg/kg Tiamulin, 110 ppm Tylosin, and 10 mg/kg Enramycin. MCT3 = NC+0.32% medium-chain-triglyceride. MCT5 = NC+0.55% (phase 1), 0.32% (phase 2, 3) medium-chain-triglyceride.
