| 摘 要： | 试验探讨维生素E对免疫抑制蛋鸡生产性能和蛋品质的调控效应,选取健康的尼克褐产蛋鸡270只,随机等分为5组,每组3个重复,每重复18只。第Ⅰ组为对照组,第Ⅱ~Ⅴ组为免疫抑制组,对第Ⅱ~Ⅴ组鸡在试验第5、6、7 d进行腿部肌肉注射80 mg/kgBW环磷酰胺(CTX),第Ⅰ组注射等量生理盐水。Ⅰ、Ⅱ组饲喂基础日粮(维生素E含量44.59 mg/kg),Ⅲ、Ⅳ、Ⅴ组在基础日粮中分别添加50、100、200 mg/kg维生素E。结果显示:①免疫抑制产蛋鸡的产蛋率、平均蛋重和平均日采食量显著降低(P<0.05),破蛋率显著升高(P<0.05)。基础日粮中添加50 mg/kg维生素E显著提高免疫抑制产蛋鸡的产蛋率、平均蛋重和平均日采食量(P<0.05),但仍低于对照组Ⅰ(P<0.05);显著降低料蛋比和破蛋率(P<0.05)。②免疫抑制产蛋鸡的蛋壳厚度、蛋壳强度和哈氏单位显著降低(P<0.05),蛋形指数和蛋黄颜色无显著改变(P>0.05);50 mg/kg维生素E添加量显著提高免疫抑制产蛋鸡的蛋壳厚度、蛋壳强度和哈氏单位(P<0.05),与对照组Ⅰ无显著差异(P>0.05)。因此,免疫抑制显著降低产蛋鸡的生产性能和蛋品质;基础日粮中添加维生素E对免疫抑制蛋鸡的生产性能和蛋品质具有明显的调控效应,且以50 mg/kg添加量效果较好。

| Abstract: | The experiment was carried out to determine the effect of dietary different levels of vitamin E on performance and egg quality in cyclophosphamide(CTX) immunosuppressed laying hens.270 Nick Red laying hens were randomly allocated into 5 groups(3 replications/group,18 hens/replication): group Ⅰ(control group),group Ⅱ(CTX group),group Ⅲ(50 mg/kg Vitamin E + CTX),group Ⅳ(100 mg/kg Vitamin E + CTX) and group Ⅴ(200 mg/kg Vitamin E + CTX).Cyclophosphamide challeng resulted in lower laying rate,average egg weight and average feed intake,higher break egg rate than the saline-treated control hens(P<0.05).The basal diet supplemented with 50 mg of vitamin E/kg of diet showed significant increase in laying rate,average egg weight,average feed intake,decrease in feed-egg ratio and break egg rate in cyclophosphamide immunosuppressed laying hens(P<0.05).Cyclophosphamide administration significantly reduced egg shell thickness,egg shell strength and haugh unit of laying hens(P<0.05),without egg shape index and yolk color.Diet added 50 mg/kg of vitamin E significantly elevated egg shell thickness,egg shell strength and haugh unit of hens under immunosuppression(P<0.05),and there was a nonsignificant difference compared to control group(P>0.05).These results suggested that vitamin E supplementation at 50 mg/kg diet enhance performance and egg quality in laying hens under immunosuppression. |
