Data of growth performance and diarrhea incidence were shown as mean ± SEM (n = 42). Data of L/M were shown as mean ± SEM (n = 6). Different superscript within a row means significantly different (P <0.05).

IBW, initial body weight; EBW, end bodyweight; ADG, average daily gain; ADFI, average daily feed intake; F/G, feed to gain ratio; L/M, lactulose/mannitol; CON, basal diet; ZnO, basal diet supplemented with ZnO (2,000 mg Zn/kg); C_ZnO, basal diet supplemented with C_ZnO (500 mg Zn/kg).
