Effect of supplemental yeast probiotic on carcass and organ weights of broilers. Significance difference is indicated by single, double and triple asterisk as: * p < 0.05 vs. control, ** p < 0.01 vs. control, *** p < 0.001 vs. control; C, control group (without probiotic); T1, first treatment group; T2, second treatment group; T3, third treatment group. The data are presented as Mean ± SEM, (n = 10). Significance difference at p < 0.05.
