中药复方对热应激下蛋鸡生化指标的影响

Effects of Compound Prescription of Chinese Herbal Medicine on the Biochemical Parameters of Laying Chicken under Heat Stress

[目的]探讨热应激下蛋鸡的生化机制。[方法]将88日龄体重大小均匀一致的蛋鸡随机分为5组,即方剂①组、方剂②组、VC组、空白组(热应激无药组)、正常组(无热应激组),研究不同中药复方对热应激状态下蛋鸡血液生化指标的影响。[结果]热应激降低了空白组蛋鸡血钠、血钾、血氯、血磷的含量,并使甘油三酯、胆固醇的含量上升。方剂①组和方剂②组血钠、血钾、血氯、血磷的含量均有明显回升,且能降低甘油三酯、胆固醇的含量,降低血清谷丙转氨酶、谷草转氨酶、乳酸脱氢酶和肌酸激酶的含量。方剂①组、方剂②组均比VC组效果明显,但方剂②组效果最为显著。[结论]中药复方对缓解蛋鸡的热应激具有显著功效。

[Objective] The research aimed to discuss the biochemical indices of laying chicken under heat stress.[Method] 88-day-old laying chicken with the same body weight were randomly divided into five groups,namely prescription ① group,prescription ② group,VC group,blank group（no drug group of heat stress） and normal group（no heat stress group）.The effects of different Chinese herbal compound on the blood biochemical indices of laying chicken under heat stress were studied.[Result] Heat stress reduced the contents of sodium,potassium,chloride and phosphorus in blank group,and increased the levels of triglyceride and cholesterol.The contents of sodium,potassium,chloride and phosphorus in prescription ① group and prescription ② group all obviously increased,the contents of triglyceride and cholesterol decreased and the concentrations of ALT,LDH,CK were decreased.The effects of prescription ① group and prescription ② group were more obvious than that of VC group and the effect of prescription ② group was the most signficiant.[Conclusion] Compound prescription of Chinese medicine had a significant effect on alleviating the heat stress of laying chicken.
