| 摘 要： | 为探讨谷氨酰胺(Gln)对免疫应激产蛋高峰期鸡生产性能和蛋品质影响,选取健康的37周龄海兰褐产蛋鸡300只,随机分为5组,每组5重复,每重复12只。Ⅰ组为对照组,饲喂基础日粮,Ⅱ、Ⅲ、Ⅳ和Ⅴ组为免疫应激组,在日粮中分别添加0%、0.6%、0.8%和1.0%的Gln。试验第4天对Ⅱ～Ⅴ组蛋鸡进行腿部肌肉注射新城疫冻干苗和油苗,Ⅰ组同部位注射等量生理盐水。结果显示,免疫应激导致蛋鸡生产性能和蛋品质有所降低,Gln添加Ⅲ组的产蛋率恢复较其他应激组快(P<0.05),Ⅱ组的料蛋比显著高于Ⅰ组(P<0.05),Ⅳ组的采食量较低,平均蛋重较高,试验后期Gln可改善蛋壳强度和蛋黄颜色(P>0.05)。免疫应激条件下,饲料添加Gln可提高蛋鸡生产性能,改善蛋品质。

| Abstract: | The experiment was carried out to determine the effect of dietary different levels of Glutamine(Gln) on the productive performance and egg quality of laying hens under immune stress.300 Hy-Line Brown hens of 37 weeks age were randomly allocated into 5 groups(5 replications per group,12 hens per replication):group Ⅰ(control group),group Ⅱ,Ⅲ,Ⅳ and Ⅴ(immune stress group,0,0.6%,0.8% and 1.0%Gln,respectively).The results showed that the performances and egg qualities of laying hens were decreased by immune stress,while the laying rate was recovered rapidly in group Ⅲ.Group Ⅱ had higher feed/egg ratio than group Ⅰ(P<0.05).Group Ⅳ had lower feed intake and higher average egg weight.Gln improved the shell strength and egg yolk color in late experiment period(P>0.05).These results suggested that Gln enhanced the production performance and improved the egg quality in laying hens under immune stress. |
