摘要： 为探讨枯草芽孢杆菌对如皋黄鸡生产性能、蛋品质、血液生化指标的影响，笔者选择体况良好、生产性能相近的250 只47 周龄如皋黄鸡，随机分为5 组，每组5 个重复，每个重复10 只。Ⅰ组为对照组，饲喂基础日粮；Ⅱ~Ⅴ组分别添加0.02%、0.075%、0.2%、0.75%的枯草芽孢杆菌，试验周期为42 天。结果表明：（1）各组间产蛋率、平均蛋重、平均日产蛋重、平均日采食量和料蛋比差异均不显著(P＞0.05)；（2）42天时试验Ⅴ组的蛋白高度极显著高于对照组(P<0.01)，且显著高于试验Ⅱ组(P<0.05)；试验Ⅲ组、Ⅳ组的蛋白高度显著高于对照组(P<0.05)；试验Ⅴ组的哈氏单位极显著高于对照组(P<0.01)，且显著高于试验Ⅱ组(P<0.05)；（3）42 天时试验Ⅳ组的尿素氮含量极显著低于对照组(P<0.01)，且显著低于试验Ⅱ组(P<0.05)；试验Ⅳ组的尿酸含量极显著低于对照组(P<0.01)，且试验Ⅱ组显著低于对照组(P<0.05)。日粮中添加枯草芽孢杆菌能够改善如皋黄鸡产蛋后期的生产性能、蛋品质和血液生化指标，提高饲料消化率，降低粪 便中氮、磷的排放量。

Abstract: The paper aims to study the effect of Bacillus subtilis on performance, egg quality and blood biochemical parameters of Rugao yellow chicken. The authors chose 250 47-week-old Rugao yellow chicken with good body condition and similar production performance, and divided them into 5 groups randomly with 5 repetitions per group and 10 per repetition. The control group Ⅰwas fed with the basal diet and Bacillus subtilis was added with the certain ratio of 0.02%, 0.075%, 0.2%, 0.75% into the basal diet for group Ⅱ-Ⅴ; the experiment lasted 42 days. The results showed that: (1) there was no significant difference between laying rate, average egg weight, average daily egg weight, average daily feed intake and ratio of feed to egg (P＞0.05) in each groups; (2) on the 42nd day, the albumen height of group Ⅴ was extremely and significantly higher than that of the control group (P<0.01) and was significantly higher than that of group Ⅱ (P<0.05); and the albumen height of group Ⅲ and Ⅳ was significantly higher than that of the control group (P<0.05); HA units of group Ⅴ was extremely and significantly higher than that of the control group (P<0.01) and was significantly higher than that of group Ⅱ (P<0.05); (3) on the 42nd day, the content of the urea nitrogen of group Ⅳ was extremely and significantly lower than that of the control group (P<0.01) and was significantly lower than that of group Ⅱ (P<0.05); the content of uric acid of group Ⅳ was extremely and significantly lower than that of the control group (P<0.01) and that of group Ⅱ was significantly lower than that of the control group (P<0.05). The basal diet added with Bacillus subtilis can improve the production performance, egg quality, blood biochemical parameters of Rugao yellow chicken, raise the feed digestion rate and reduce the emissions of nitrogen and phosphorus in faeces.
