【摘要】：本试验旨在研究复合益生菌对肉鸽生长性能和免疫机能的影响。选取72对种鸽和144只1日龄乳鸽,乳鸽称量初始体重后随机分成4个试验组,每个试验组6个重复,每个重复3对种鸽及6只乳鸽。各组饲喂相同基础日粮,对照组补饲保健砂,Ⅰ组补饲保健砂+复合菌Ⅰ(6×10~7 CFU/g嗜酸乳杆菌+6×10~7 CFU/g乳双歧杆菌),Ⅱ组补饲保健砂+复合菌Ⅱ(6×10~7 CFU/g乳双歧杆菌+6×10~7 CFU/g粪肠球菌),Ⅲ组补饲保健砂+复合菌Ⅲ(6×10~7 CFU/g嗜酸乳杆菌+6×10~7 CFU/g粪肠球菌)。试验期56d。结果显示,与对照组相比,Ⅱ组显著提高了肉鸽的28和56日龄体重和平均日增重(P0.05)。Ⅱ组显著提高了28日龄肉鸽的胸腺指数(P0.05);Ⅲ组显著提高了56日龄肉鸽的脾脏指数(P0.05)。3个复合菌组提高了28和56日龄肉鸽血清中免疫球蛋白的含量,但均未达到显著水平(P0.05)。综上所述,保健砂中添加复合益生菌可提高肉鸽的生长性能、免疫器官指数,并一定程度上能提高肉鸽的免疫力,其中乳双歧杆菌和粪肠球菌组效果最好。
[Abstract]:The purpose of this experiment was to study the effect of compound probiotics on growth performance and immune function of meat pigeon. Seventy-two pairs of breeding pigeons and 144 1-day-old squab were selected. After weighing their initial body weight, the pigeons were randomly divided into 4 groups, with 6 replicates in each group, 3 pairs of breeding pigeons and 6 pigeons in each replica. Each group was fed with the same basic diet, while the control group was supplemented with health care sand. Group 鈪，
