【摘要】：为探讨益生菌与中草药联合应用对产蛋鸡饲养的效果,以480只32周龄海兰褐蛋鸡为研究对象,随机分为4组,每组3个重复,每个重复40只鸡。对照组饲喂基础日粮,试验1、2和3组均在基础日粮中添加1.0%的中草药组分,再依次分别添加0.05%、0.1%和0.2%的复合益生菌。预试期7 d,正试期28 d,考察益生菌与中草药联合应用对产蛋鸡生产性能和蛋品质的影响。试验结果表明,各试验组与对照组相比,均显著降低了蛋鸡的不合格蛋率(P0.05),试验2、3组还分别显著降低了料蛋比和提升了产蛋率(P0.05);同时,各试验组均显著提高了鸡蛋的蛋黄颜色(P0.05),试验2、3组还显著提高了蛋壳厚度和蛋黄比率(P0.05)。但是,试验2组和试验3组的生产性能、蛋品质差异不显著(P0.05)。由此可知,联合应用益生菌和中草药可改善蛋鸡的生产性能,提高蛋品质,综合应用的效果和添加量,其中以试验2组的益生菌和中草药为最佳应用组合。
[Abstract]:In order to investigate the effect of probiotics combined with Chinese herbal medicine on laying hens, 480 Hailan brown laying hens aged 32 weeks were randomly divided into 4 groups, 3 replicates in each group and 40 in each. The control group was fed with basal diet. In experiment 1, both groups 2 and 3 added 1.0% of Chinese herbal medicine to the basal diet, and 0.05% and 0.2% of compound probiotics, respectively. The effects of the combination of probiotics and Chinese herbal medicine on the performance and egg quality of laying hens were investigated. The results showed that, compared with the control group, the unqualified egg rate of the control group was significantly decreased, and the feed / egg ratio and the egg laying rate were significantly decreased in the experiment 2 / 3, respectively, and the egg laying rate was also increased, and the egg production rate of the control group was significantly lower than that of the control group, at the same time, there was no significant difference between the two groups. The yolk color of eggs was significantly increased in each test group, and the egg shell thickness and yolk ratio were also significantly increased in test 2 and 3 groups. However, there was no significant difference in production performance and egg quality between group 2 and group 3 (P 0.05). It can be seen that the combination of probiotics and Chinese herbal medicine can improve the performance of laying hens, improve egg quality, comprehensive application effect and addition amount, among which the best combination of probiotics and Chinese herbal medicine is used in test 2 groups.
