ABSTRACT
The present study aimed to study the effects of applying mixed probiotics in the feed on growth performance,antioxidant activity and immune function in yellow-feathered broilers.Three hundred sixty yellow-feathered broilers at 10-day-old were divided into 4 groups.Group A was fed with basal diets,group B with basal diets added 50 g/t mixed probiotics,group C with basal diets added 100 g/t mixed probiotics and group D with basal diets added 300 g/t mixed probiotics.Each group included 9 replicates(10 birds per replicates),and the experiment lasted 50 days.Results showed that group D got the highest average daily gain(ADG) of all groups,and compared with the control group A,ADG was increased by 4.11% (P<0.05).Group B got the lowest feed-gain ratio of all groups,and the feed-gain ratio was decreased by 4.58%(P<0.05) compared with the control group A.Group D got significantly increased duodenal villous length,serum antioxidant index and antibody titer(P<0.05) compared with the control group A.The effects of mixed probiotics on the growth performance,antioxidant activity and immune function were distinct in yellow-feathered broilers,and 100 g/t mixed probiotics was recommended.
