摘　　要：本试验旨在研究复合益生菌对乳鸽生长性能、屠宰性能、免疫器官指数和血清生化指标的影响。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个组,每个组6个重复,每个重复3对种鸽及6只乳鸽。在饲喂相同基础饲粮的同时,对照组补饲保健砂,Ⅰ组补饲保健砂+复合菌Ⅰ(嗜酸乳杆菌+乳双歧杆菌),Ⅱ组补饲保健砂+复合菌Ⅱ(乳双歧杆菌+粪肠球菌),Ⅲ组补饲保健砂+复合菌Ⅲ(嗜酸乳杆菌+粪肠球菌)。试验期28 d。结果表明:与对照组相比,1)在生长性能方面,Ⅱ组显著提高了乳鸽的28日龄体重和平均日增重(P<0.05)。2)在屠宰性能方面,Ⅱ组显著提高了乳鸽的屠宰率、半净膛率和全净膛率(P<0.05);Ⅰ组和Ⅲ组显著降低了乳鸽的腹脂率(P<0.05)。3)在免疫器官指数方面,Ⅱ组显著提高了乳鸽的胸腺指数(P<0.05)。4)在血清生化指标方面,Ⅰ组和Ⅲ组显著降低了乳鸽血清中总蛋白和球蛋白的含量(P<0.05);Ⅰ组、Ⅱ组和Ⅲ组均显著降低了乳鸽血清中肌酐的含量(P<0.05);Ⅱ组和Ⅲ组显著降低了乳鸽血清中甘油三酯的含量(P<0.05);Ⅱ组显著增加了乳鸽血清中高密度脂蛋白的含量(P<0.05)。综上所述,保健砂中添加复合益生菌改善了乳鸽的生长性能、屠宰性能、免疫器官指数和血清生化指标。This experiment was conducted to investigate the effects of compound probiotics on growth performance, slaughter performance, immune organ index and serum biochemical parameters of squabs. Seventy-two pairs of breeding pigeons and 144 squabs were selected and randomly divided into 4 groups with 6 replicates per group and 3 pairs of breeding pigeons and 6 squabs per replicate. In fed the same basal diet at the same time, the control group was fed the health care sand, groups Ⅰ, Ⅱ and Ⅲ were fed the health care sand with compound probiotics Ⅰ （Lactobacillus acidophilus＋Bifidobacterium lactis）, compound probiotics Ⅱ （Bifidobacterium lactis＋Enterococcus faecalis） and compound probiotics Ⅲ （Lactobacillus acidophilus＋Enterococcus faecalis）, resperctively. The experiment lasted for 28 days. The results showed as follows： compared with the control group, 1） in the aspect of growth performance, group Ⅱ significantly increased the body weight at 28 days of age and the average daily gain of squabs （P〈0.05）. 2） In the aspect of slaughter performance, group Ⅱ significantly increased the slaughter rate, semi-eviscerated rate and eviscerated rate of squabs （P〈0.05）, group Ⅰ and group Ⅲ significantly reduced the abdominal fat rate of squabs （P〈0.05））. 3） In the aspect of immune function, group Ⅱ significantly increased thymus index of squabs （P〈0.05）. 4） In the aspect of serum biochemical index, group Ⅰ and group Ⅲ significantly reduced the content of total protein and globulin in serum of squabs （P〈0.05）, group Ⅰ, group Ⅱ and group Ⅲ significantly reduced the serum creatinine content of squabs （P〈0.05）, group Ⅱ and group Ⅲ significantly reduced the serum triglycerides content of squabs （P〈0.05）, group Ⅱ significantly increased the serum high density lipoprotein content of squabs （P〈0.05）. In summary, compound probiotics added in the health care sand can improve the growth performance, slaughter performance, immune
