女贞子、五味子与寡糖配伍对肉鸡生产性能和免疫功能的影响

Effects of Ligustrum Lucidum, Schisandra Chinensis and MOS on Growth Performance and Immunity of Broilers

研究了中草药女贞子、五味子以及女贞子、五味子与葡萄糖甘露寡糖(MOS)配伍对肉鸡生产性能及免疫功能的影响。选择180只肉鸡公雏随机分为6组,空白组饲喂基础饲粮,抗生素组在基础饲粮中添加5mg/kg黄霉素,试验组分别在基础饲粮中添加1%女贞子、五味子、女贞子+MOS、五味子+MOS。试验从1日龄开始,试验期56d。结果表明:五味子+MOS在肉鸡生长中、后期能显著提高肉鸡的体增重;女贞子能提高肉鸡的ND抗体效价;各试验组均显著提高了鸡脾淋巴细胞在ConA诱导下的增殖反应。说明中草药添加剂能够提高肉鸡的体增重、增强肉鸡的免疫性能。

Effects of Ligustrum Lucidum (LL), Schisandra Chinensis (SC), mannanoligosaccharides(MOS) and flavomycin on growth performance and immunity of broilers were studied. 180 broilers of 1-day old were randomly assigned to six groups. The blank was provided with basal diet, the antibiotic group was provided with basal diet with addition of 5mg/kg flavomycin. Other trial groups were provided with basal diet plus 1%LL, 1%SC, 1%LL+MOS, 1%SC+MOS. The broilers were fed their respective diets from 1-day to 56 days old. The results showed that SC+MOS can significant improve performance of broilers in middle and later period. LL increased antibody level significantly. Lymphocyte proliferative responses to ConA were greater (P<0.05) in all of trial groups. Chinese herb additive can improve growth performance and immunization of broilers.
