  1. Data are expressed as mean ± SEM. Sows were regarded as the experimental units, n = 10 for each treatment. LZM 150 = control diet + lysozyme 150 mg/kg, LZM 300 = control diet + lysozyme 300 mg/kg. SCFAs is the sum of acetate, propionate, and butyrate. a,bWithin a row, means with different superscripts are different (P < 0.05).
