摘要
探讨中药复方对慢性热应激下蛋鸡生产性能和心脏组织HSP70表达量的影响。选取250只60日龄蛋鸡,随机分为空白对照组、维生素C组、复方Ⅰ、复方Ⅱ、复方Ⅲ组。每天记录各组的耗料量、蛋重、产蛋量、淘死数以及软、破蛋数量,采用ELISA法测定蛋鸡心脏组织HSP70表达量。结果显示,中药复方能够改善热应激状态下蛋鸡的生产性能,其中复方Ⅱ的效果最佳;中药复方组蛋鸡心脏组织HSP70表达量均低于空白对照组,其中方Ⅱ组下降的幅度最大,表明各中药复方均能提高热应激蛋鸡的生产性能,其作用机制可能与调控HSP70表达量有关。
To explore the compound Chinese herbal prescription on the performance and expression of HSP70 in heart tissues of laying hens under chronic heat stress,two hundred 60-day-old laying hens were randomly divided into five groups： control group,vitamin C-group,treated Ⅰ-group,treated Ⅱ-group and treated Ⅲ-group.Egg quantity and feed intake were recorded every day.The expression level of HSP70 in heart tissue of all groups was detected by ELISA.All of the compound Chinese herbal prescription could improve the performance of laying hens under heat stress,and the treated Ⅱ-group gave the best efficacy.Compound Chinese herbal prescription drugs decreased the expression of HSP70 in heart tissue of laying hens under chronic heat stress in which the treated Ⅱ-group was the lowest.It indicated that the compound traditional Chinese medicine could improve the production performance of laying hens under heat stress,which may be related with the regulation of HSP70 expression.
