NC, negative control group; PC, positive control group; M, Maxus supplemented group; CL, CloStat supplemented group; S, Sangrovit Extra supplemented group; CL+S, CloStat+Sangrovit Extra supplemented group; G, Gallipro Tech supplemented group. IBW, initial body weight; FBW, final body weight; FI, feed intake; BWG, body weight gain; FCR, feed conversion ratio; PEF, protein efficiency ratio; SR, survival rate. SEM, mean values of standard error. Mean values of three replicates with deferent letter (a, b, c) in the same column are significantly deferent (p < 0.05). Sig., significance; N.S, non-significance; ***, significant at 0.001.
