摘要

本试验旨在研究饲粮中添加枯草芽孢杆菌和丁酸梭菌对五龙鹅雏鹅生长性能、屠宰性能、血清生化指标及抗氧化能力的影响。选择1日龄体重相近的健康五龙鹅雏鹅200只,随机分为4个组,每组5个重复,每个重复10只鹅。Ⅰ组(对照组)饲喂基础饲粮,Ⅱ组在基础饲粮中添加250 mg/kg枯草芽孢杆菌,Ⅲ组在基础饲粮中添加250 mg/kg丁酸梭菌,Ⅳ组在基础饲粮中添加250 mg/kg枯草芽孢杆菌+250 mg/kg丁酸梭菌。试验期4周。结果表明:1)与对照组比较,Ⅱ、Ⅲ、Ⅳ组鹅末重分别提高了7.78%(P<0.05)、3.12%(P>0.05)和9.54%(P<0.05),平均日增重分别提高了7.89%(P<0.05)、3.39%(P>0.05)和10.18%(P<0.01),料重比分别降低了4.96%(P<0.05)、1.65%(P>0.05)和6.20%(P<0.05)。2)与对照组比较,Ⅱ、Ⅲ、Ⅳ组鹅胸肌率分别提高了2.10%(P>0.05)、2.80%(P>0.05)和4.20%(P<0.05),腿肌率分别提高了9.50%(P<0.05)、8.60%(P<0.05)和10.86%(P<0.05),腹脂率分别降低了7.74%(P<0.05)、5.81%(P>0.05)和10.97%(P<0.05)。3)与对照组比较,Ⅱ、Ⅲ、Ⅳ组鹅血清总抗氧化能力分别提高了4.46%(P>0.05)、3.39%(P>0.05)和12.33%(P<0.05),血清总超氧化物歧化酶活性分别提高了4.94%(P<0.05)、3.30%(P>0.05)和7.69%(P<0.01)。由此可见,饲粮中添加枯草芽孢杆菌和丁酸梭菌能够提高五龙鹅雏鹅生长性能、屠宰性能和抗氧化能力,二者配合使用的效果优于单一菌种。

Abstract

This study aimed to investigate the effects of dietary Bacillus subtilis and Clostridium butyricum on growth performance, slaughter performance, serum biochemical indices and antioxidant capacity of Wulong goslings. A total of 200 healthy one-day-old Wulong geese with similar body weight were randomly divided into 4 groups with 5 replicates in each group and 10 geese in each replicate. Geese in group Ⅰ (control group) were fed a basal diet, geese in group Ⅱ were fed the basal diet supplemented with 250 mg/kg Bacillus subtilis, geese in group Ⅲ were fed the basal diet supplemented with 250 mg/kg Clostridium butyricum, and geese in group Ⅳ were fed the basal diet supplemented with 250 mg/kg Bacillus subtilis+250 mg/kg Clostridium butyricum. The experiment lasted for 4 weeks. The results showed as follows:1) compared with the control group, the final weight of geese of groups Ⅱ, Ⅲ and Ⅳ was increased by 7.78% (P<0.05), 3.12% (P>0.05) and 9.54% (P<0.05), respectively; the average daily gain was increased by 7.89% (P<0.05), 3.39% (P>0.05) and 10.18% (P<0.01), respectively; the feed to gain ratio was decreased by 4.96% (P<0.05), 1.65% (P>0.05) and 6.20% (P<0.05), respectively. 2) Compared with the control group, the percentage of breast muscle of geese of groups Ⅱ, Ⅲ and Ⅳ was increased by 2.10% (P>0.05), 2.80% (P>0.05) and 4.20% (P<0.05), respectively; the percentage of leg muscle was increased by 9.50% (P<0.05), 8.60% (P<0.05) and 10.86% (P<0.05), respectively; the percentage of abdominal fat was decreased by 7.74% (P<0.05), 5.81% (P>0.05) and 10.97% (P<0.05), respectively. 3) Compared with the control group, the serum total antioxidant ability of geese of groups Ⅱ, Ⅲ and Ⅳ was increased by 4.46% (P>0.05), 3.39% (P>0.05) and 12.33% (P<0.05), respectively; the serum total superoxide dismutase activity was increased by 4.94% (P<0.05), 3.30% (P>0.05) and 7.69% (P<0.01), respectively. In conclusion, dietary Bacillus subtilis and Clostridium butyricum can improve the growth performance, slaughter performance and antioxidant capacity of Wulong goslings, and the effects of combined use of the two bacteria is better than that of a single strain.
