Comparison of the effects of compound probiotics and antibiotics on yellow-feather broilers based on growth performance, small intestine morphology and digestive enzymes activity, gut microbiota and fecal emissions
Abstract:This study was devoted to the comparison of the probiotic effect of compound probiotics to the antibiotics as a chicken feed additive. Two hundred and seventy newly-hatched yellow-feather broilers were randomly divided into 3 groups, control group (Con), probiotics (Pb) and antibiotics group (Ab).
