摘要：

试验旨在研究中草药-益生菌-胆汁酸复合制剂对蛋鸡生产性能、蛋品质及免疫指标的影响。选用495日龄海兰褐健康蛋鸡160只，随机分成2组，每组4个重复，每个重复20只。对照组饲喂基础日粮，试验组在基础日粮中添加0.2%中草药-益生菌-胆汁酸复合制剂（黄芪、当归、乳酸杆菌、胆汁酸等），检测其对海兰褐蛋鸡生产性能、蛋品质及免疫指标的影响。预饲期1周，试验期3周。结果显示：试验组的产蛋率、平均蛋重、平均日采食量较对照组分别提高4.97%、1.71%、0.49%，料蛋比降低6.33%。试验组的蛋白高度、蛋黄颜色、哈氏单位分别较对照组提高9.87%、6.64%、3.94%。与对照组相比，试验组的IgA提高2.38%，IgG提高1.51%。对蛋鸡粪便中乳酸杆菌和大肠杆菌的计数发现，试验组粪便中的乳酸杆菌数量显著高于对照组（P < 0.05），大肠杆菌数量显著低于对照组（P < 0.05）。综上所述，日粮中添加0.2%中草药-益生菌-胆汁酸复合制剂在一定程度上可改善蛋鸡的生产性能和蛋品质，同时提高其免疫力和抗病能力。

Abstract:

This experiment was conducted to investigate the effect of Chinese herbal-probiotics-bile acids compound on production performance,egg quality and immune indexes of laying hens.160 495-day-old Hy-Line Brown hens in healthy were chosen and divided into 2 groups with 4 replicates per group and 20 hens per replicate.The hens in control group were fed a basal diet and that in the experimental group were fed the basal diets supplemented with 0.2% Chinese herbal-probiotics-bile acids compound (Astragalus,Angelica ainensis,Lactobacillus,bile acids,etc).The preliminary trial lasted for 1 week,and the experimental period lasted for 3 weeks.The results showed that the laying rate, average egg weight and average daily feed intake of the experimental group were increased by 4.97%,1.71% and 0.49% than that of the control group and feed/egg of the experimental group was decreased by 6.33% than that of the control group.The experimental group of protein height,yolk color and Haugh units were higher than the control group by 9.87%,6.64% and 3.94%.The IgA and IgG of experimental group were increased by 2.38% and 1.51% than that of the control group,respectively.The quantities of Lactobacillus in feces of the experimental group were significantly higher than that in the control group (P < 0.05),while the E.coli in the experimental group were significantly lower (P < 0.05).In conclusion,the addition of Chinese herbal-probiotics-bile acid compound preparation for the laying hens could improve the production performance and egg quality,and have a certain effect in improving immunity and disease resistance.

Key words: Chinese herbal-probiotics-bile acid compound; laying hens; production performance; egg quality; immune indexes
