试验的目的是研究益生素和酵母细胞壁不同配比浓度对蛋鸡生产性能的影响，开发无抗蛋鸡日粮。选择体重相近、健康的华裕海兰褐蛋鸡4万羽，随机分成4组，分别饲喂基础饲粮（对照组，A组）、基础饲粮＋400g/t酵母细胞壁＋50 g/t 益生素（B组）、基础饲粮＋800 g/t酵母细胞壁＋100 g/t 益生素（C组）、基础饲粮＋1200 g/t 酵母细胞壁＋150 g/t益生素（D组）。试验期为28～50周龄。结果表明：整个试验期各组间蛋鸡日采食量、平均蛋重没有显著差异（P＞0.05）。与A组相比，B、C和D组蛋鸡产蛋率分别提高了2.99%（P＜0.05）、5.60%（P＜0.05）和2.94%（P＜0.05），料蛋比分别下降了1.43%（P＞0.05）、6.67%（P＜0.01）和2.38%（P＜0.05）。与B、D组相比，C组蛋鸡产蛋率分别提高了2.48%（P＞0.05）、2.52%（P＞0.05）；料蛋比下降了5.61%（P＞0.05）、4.26%（P＜0.05）。结果提示，饲粮中添加酵母细胞壁、益生素组合对蛋鸡生产性能影响明显，饲粮中添加800 g/t 酵母细胞壁＋100 g/t 益生素（C组）效果最佳。运用系统而综合的免疫管理措施，适宜浓度的益生素和酵母细胞壁组合有效地促进了有益菌在肠道的定殖增殖、提高了肠道的屏障功能以及增强免疫细胞的免疫活性，试验证明其可以替代蛋鸡饲料中抗生素的使用，维持蛋鸡高水平的健康状况。
試驗的目的是研究益生素和酵母細胞壁不同配比濃度對蛋鷄生產性能的影響，開髮無抗蛋鷄日糧。選擇體重相近、健康的華裕海蘭褐蛋鷄4萬羽，隨機分成4組，分彆飼餵基礎飼糧（對照組，A組）、基礎飼糧＋400g/t酵母細胞壁＋50 g/t 益生素（B組）、基礎飼糧＋800 g/t酵母細胞壁＋100 g/t 益生素（C組）、基礎飼糧＋1200 g/t 酵母細胞壁＋150 g/t益生素（D組）。試驗期為28～50週齡。結果錶明：整箇試驗期各組間蛋鷄日採食量、平均蛋重沒有顯著差異（P＞0.05）。與A組相比，B、C和D組蛋鷄產蛋率分彆提高瞭2.99%（P＜0.05）、5.60%（P＜0.05）和2.94%（P＜0.05），料蛋比分彆下降瞭1.43%（P＞0.05）、6.67%（P＜0.01）和2.38%（P＜0.05）。與B、D組相比，C組蛋鷄產蛋率分彆提高瞭2.48%（P＞0.05）、2.52%（P＞0.05）；料蛋比下降瞭5.61%（P＞0.05）、4.26%（P＜0.05）。結果提示，飼糧中添加酵母細胞壁、益生素組閤對蛋鷄生產性能影響明顯，飼糧中添加800 g/t 酵母細胞壁＋100 g/t 益生素（C組）效果最佳。運用繫統而綜閤的免疫管理措施，適宜濃度的益生素和酵母細胞壁組閤有效地促進瞭有益菌在腸道的定殖增殖、提高瞭腸道的屏障功能以及增彊免疫細胞的免疫活性，試驗證明其可以替代蛋鷄飼料中抗生素的使用，維持蛋鷄高水平的健康狀況。

The purpose of this experiment was to study the effects of different probiotics and yeast cell wall concentrations on perfor﹣mance of layer and develop non-antibiotic feed for layer. In the experiment, 40 000 healthy Hailan-brown laying hens with similar body weight were randomly divided into four groups, and fed basal diet (control group, A group), basal diet+400 g/t yeast cell wall+50 g/t probiotics (group B), basal diet + 800 g/t yeast cell wall + 100 g/t probiotics (group C), basal diet + 1 200 g/t yeast cell wall +150 g/t probiotics (group D), respectively. Experiment started at age of 28 weeks and ended at the age of 50 weeks. The results showed that daily feed intake and average egg weight were not significantly different (P>0.05)between the groups throughout the test period. Compared with group A, laying rate of layers in group B、C and D was increased by 2.99% (P<0.05)、5.60%(P<0.05)and 2.94%(P<0.05), feed to egg ratio was decreased by 1.43% (P>0.05), 6.67%(P<0.01)and 2.38%(P<0.05), respectively. Compared with the B, D, laying rate of group C was increased by 2.48% (P>0.05)and 2.52%(P>0.05); feed egg ratio was decreased by 5.61% (P>0.05)and 4.26%(P<0.05), respectively. Results suggested that yeast cell wall and probiotics had significant effect on performance of laying hen, adding 800 g/t yeast cell wall+100 g/t probiotics (group C) to diet had best effect. Systemic and comprehensive immune management and proper concentration of probiotics and yeast cell wall in diet could effectively promote the proliferation of beneficial bacteria in gut colonization and improve intestinal barrier function and enhance immune activity of immune cells. The experiment confirms that proper concentration of probiotics and yeast cell wall can replace antibiotics for feed of hens, maintain hens in a high level of health.
