【摘要】：研究探讨了饲粮中添加丁酸梭菌和低聚木糖对肉鸡生产性能、屠宰性能和肉品质的影响及其互作效应。288只21日龄Ross308肉鸡随机分成4组(对照组、丁酸梭菌组、低聚木糖组和丁酸梭菌+低聚木糖组),每组6个重复。结果表明:同时添加丁酸梭菌和低聚木糖能显著提高肉鸡平均日增重,降低料肉比(P0.05),两者有明显的互作效应(P0.05);添加丁酸梭菌能显著提高肉鸡的胸肌率(P0.05),单独添加丁酸梭菌和低聚木糖以及同时添加两者能显著降低肉鸡的腹脂率,两者互作效应明显(P0.05);同时添加丁酸梭菌和低聚木糖能显著提高胸肌的p H45 min及降低滴水损失(P0.05),且互作效应明显(P0.05);添加丁酸梭菌及同时添加丁酸梭菌和低聚木糖能显著提高胸肌的红度(a*)(P0.05)。综上所述,丁酸梭菌和低聚木糖可互作改善肉鸡生产性能、屠宰性能和肉品质。
[Abstract]:The effects of Clostridium butyrate and xylooligosaccharide on the performance, slaughter performance and meat quality of broilers and their interaction effects were studied. 288 21-day-old Ross308 broilers were randomly divided into 4 groups (control group, clostridium butyrate group).Xylooligosaccharide group and clostridium butyricum oligosaccharide group, 6 repeats in each group.The results showed that the addition of Clostridium butyrate and xylooligosaccharide could significantly increase the average daily gain of broilers.Adding Clostridium butyrate can significantly increase the pectoralis rate of broilers, and adding Clostridium butyrate and xylooligosaccharide alone can significantly reduce the abdominal fat rate of broilers.Addition of Clostridium butyrate and xylooligosaccharide could significantly increase the pH 45 min of pectoralis muscle and decrease water loss (P 0.05), and the interaction effect was significant (P 0.05), and the addition of Clostridium butyrate and the addition of Clostridium butyrate and xylooligosaccharide could significantly increase the pH 45 min and decrease the water loss of pectoralis.The red degree of pectoralis muscle was increased significantly (P 0.05).In conclusion, clostridium butyrate and xylooligosaccharide could improve the performance, slaughter performance and meat quality of broilers.
