| 摘 要： | 研究一株植物乳酸杆菌细菌素对蛋鸡生产性能和蛋品质的影响。选用232日龄产蛋率和体重相近、健康状况良好的海兰灰蛋鸡225只,试验期为34 d。结果表明:日粮中添加500 AU/kg植物乳酸杆菌细菌素对蛋鸡的产蛋率和平均蛋重的提升幅度最大,各细菌素添加组对降低料蛋比均有显著的效果(P<0.05),对平均日采食量、蛋黄色泽、哈氏单位、蛋壳强度和蛋形指数都有不同程度的改善。植物乳酸杆菌细菌素可以明显改善蛋鸡生产性能和蛋品质,可以为饲料添加剂的研发提供新的思路。

| Abstract: | To study effect of the fermentation broth of a bacteriocin-producing Lactobacillus plantarum YJG on production performance and egg quality of laying hens.Two hundred and twenty five laying hens of 232-day-old were randomly divided into 5 treatment groups with 5 replicates,and the trials period was 34 days.The results showed that treatment with 500 AU/kg bacteriocin could enhance the average weight,and the treatments with bacteriocins could apparently reduce the feed egg ratio(P<0.05),Bacteriocins produced by Lactobacillus plantarum YJG could improve the production performance and egg quality of laying hens and provide new insight into research of feed additives. |
