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。

Abstract

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 organ index and serum biochemical index of squabs.

Key words： compound probiotics; squabs; growth performance; serum biochemical index
