摘要
研究旨在探讨黄芪多糖和枯草芽孢杆菌合剂对白羽王鸽乳鸽生长性能与免疫功能的影响.试验选取320对健康的白羽王鸽种鸽和640羽同日出孵体重接近的乳鸽,每对种鸽哺育2只乳鸽,将其随机分成4组,每组4个重复,每个重复20对种鸽和40只乳鸽.对照组饲喂基础日粮,试验组分别在基础日粮中添加0.1％黄芪多糖(黄芪多糖组)、0.1％枯草芽孢杆菌(枯草芽孢杆菌组)、0.1％黄芪多糖+0.1％枯草芽孢杆菌合剂(黄芪多糖+枯草芽孢杆菌组).试验期28d.结果显示,与对照组相比,黄芪多糖+枯草芽孢杆菌组乳鸽末重提高2.86％(P＜0.05),黄芪多糖组、黄芪多糖+枯草芽孢杆菌组乳鸽平均日增重提高1.68％和2.91％(P＜0.05).与对照组相比,枯草芽孢杆菌组、黄芪多糖+枯草芽孢杆菌组脾脏指数分别提高了 41.67％和47.92％(P＜0.05),黄芪多糖+枯草芽孢杆菌组法氏囊指数提高了 41.76％(P＜0.05).与对照组相比,黄芪多糖组、枯草芽孢杆菌组、黄芪多糖+枯草芽孢杆菌组乳鸽血清新城疫抗体滴度分别提高了 8.96％、8.02％、18.28％(P＜0.05).与对照组相比,黄芪多糖+枯草芽孢杆菌组乳鸽血清免疫球蛋白A(IgA)含量提高了 10.95％(P＜0.05),枯草芽孢杆菌组、黄芪多糖+枯草芽孢杆菌组乳鸽血清免疫球蛋白G(IgG)含量分别提高了 4.87％和7.44％(P＜0.05).研究表明,日粮中添加黄芪多糖和枯草芽孢杆菌合剂可显著提高乳鸽生长性能和免疫功能,结果可为进一步推动替抗合生元制剂在肉鸽养殖中的规模化应用提供参考.
Abstract
The aim of the study was to discuss the effects of Astragalus polysaccharide and Bacillus subtilis mixture on growth performance and immune function of white royal pigeon squab.A total of 320 healthy pairs of white royal pigeon breeding pigeons and 640 squabs with similar body weight hatched in the same day were selected and fed two squabs per pair.They were randomly divided into four groups with four replicates per group and 20 breeding pairs and 40 squabs per replicate.Breeding pairs in the control group were fed a basic diet,and those in the experimental groups were fed the basic diet supplemented with 0.1％Astragalus polysaccharide(Astragalus polysaccharide group),0.1％Bacillus subtilis(Bacillus subtilis group),0.1％Astragalus polysaccharide+0.1％Bacillus subtilis mixture(Astragalus polysaccharide+Bacillus subtilis group),respectively.The experiment lasted for 28 d.The results showed that compared with the control group,the final weight of squabs in the Astragalus polysaccharide+Bacillus subtilis group was increased by 2.86％(P＜0.05),and the average daily gain of squabs in the Astragalus polysaccharide group and Astragalus polysaccharide+Bacillus subtilis group the and Astragalus polysaccharide+Bacillus subtilis group were increased by 41.67％and 47.92％(P＜0.05),respectively,and the bursa of Fabricius index of the Astragalus polysaccharide+Bacillus subtilis group was increased by 41.76％(P＜0.05).Compared with the control group,the serum Newcastle disease antibody titers of squabs in Astragalus polysaccharide group,Bacillus subtilis group and Astragalus polysaccharide+Bacillus subtilis group were increased by 8.96％,8.02％and 18.28％,respectively(P＜0.05).Compared with the control group,serum IgA content in Astragalus polysaccharide+Bacillus subtilis group was increased by 10.95％(P＜0.05),serum IgG content in Bacillus subtilis group and Astragalus polysaccharide+Bacillus subtilis group was increased by 4.87％and 7.44％(P＜0.05),respectively.The results show that supplementation of Astragalus polysaccharide and Bacillus subtilis mixture can significantly improve the growth performance and immune function of squabs,and provide a reference for further promoting the large-scale application of antibiostime preparation in meat pigeon breeding.
