| 摘 要： | 旨在研究饲粮中添加维生素E对高温应激条件下蛋鸡的血液生化指标和产蛋性能的影响。选取健康的41周龄京粉一号蛋鸡360只，分为4个处理组，每组3个重复，每个重复30只鸡。设第Ⅰ组为对照组，第Ⅱ，Ⅲ，Ⅳ组为试验组，分别在日粮中添加不同水平的维生素E（0，100，200，300 mg·kg-1 ），预试1周，试验期为6周。试验结果表明，在热应激（26～33 ℃、平均29 ℃）状态下，额外添加维生素E的试验组谷草转氨酶（AST）上升（P<0.05），低密度脂蛋白（LDLC）、血糖（GLU）下降（P<0.05）。产蛋性能方面，3个试验组在料蛋比和产蛋率方面均有提升（P<0.05），添加量为100～200 mg·kg-1时，蛋鸡产蛋性能最好。试验表明，高温应激条件下，日粮中额外添加100～200 mg·kg-1水平的维生素E可以显著改善热应激环境下蛋鸡的生产性能，而对其部分血液生化指标也有显著的影响。

| Abstract: | The influence of dietary vitamin E （VE） supplementation on blood biochemical index and laying performance of hens in high temperature environment was investigated in this study. Three hundred and sixty 41\|week\|old healthy laying hens of Jingfen I were divided into 4 groups. Each group had 3 repeats and each repeat had 30 hens. Group I was the control group （basal diet）， group Ⅱ （basal diet+100 mg·kg-1 VE）， group Ⅲ （basal diet+200 mg·kg-1 VE） and group Ⅳ （basal diet+300 mg·kg-1 VE） were treatment groups. The first week was set for an adjustment period， the following six weeks were set for experimental period. The results showed that aspartate transaminase （AST） activity in the control group was significantly lower than those in VE added groups under heat stress （26-33℃， average of 29℃）（P<0.05）， and low density lipoprotein cholesterol （LDLC） and glucose （GLU） contents were significantly higher than those in treatment groups under heat stress （P<0.05）. As for laying performance， feed\|gain ratio and egg laying rate of treatment groups were significantly higher than those of the control group （P<0.05）， among which the treatments of 100-200 mg·kg-1 VE showed the best laying performance. In conclusion， under the condition of heat stress， the egg laying performance of laying hens could be significantly improved when the basal diet was added with 100-200 mg·kg-1 VE， and some biochemical indexes were significantly affected as well. |
