中草药微生态制剂替代抗生素对黄羽肉鸡生产性能、免疫机能和脏器组织的影响
Effects of Composite Herbal-probiotics agents Substitute for Antibiotic on Growth performance,immune function and organs & tissue development of Yellow Broilers
摘要
Abstract
The present study was aimed to study the effects of applying composite herbal-probiotics agents in the feed on growth performance,immune function and organs & tissue development in Yellow-feathered broilers.Five hundred Yellow-feathered broilers at 10-day-old were divided into 5 groups.Group A was fed a basal diet,group B was fed the basal diet+50 g/t aureomycin and 40 g/t bacitracin zinc,group C was fed the basal diet+5 kg/t composite herbal agents,group D was fed the basal diet+0.1 kg/t probiotics agents and group E was fed the basal diet+5.1 kg/t composite herbalprobiotics agents.Each group included 10 replicates(10 birds per replicates),and the experiment lasted 50 days.Results showed that group E got the best experimental results of all groups,ADG was increased by 8.2％(P＜0.05),the feed-gain ratio was decreased by 6.0％(P＜0.05),and survival rate increased by 2.4％ compared with the antibiotic group B.Group E also got significantly increased immune organ indexes and antibody titer of Avian influenza vaccine(P＜0.05),and enhance development of the duodenum,liver and kidney.In conclusion,the results suggest that the composite herbal-probiotics additives can improve growth performance,increase health degree,immunity and survival rate of Yellow-feathered broilers,and has the potential to replace antibiotics for broiler breeding.关键词
