摘要
[Objective] This study was conducted to investigate the effects of tradi- tional Chinese herbal medicines on blood biochemical indices of egg-laying hens under heat stress and to provide theoretical basis for clinical application of the medicines. [Method] One hundred of 88-day-old ISA-Brown hens were randomly di- vided into five groups. The hens in four groups were administrated with Prescription I herbal medicines, Prescription II herbal medicines, Vc and blank control under ar- tificially simulated heat stress, respectively. The last group was raised under normal temperature condition. Blood samples of the hens were collected on 1, 4, 8 and 10 d later and detected for their biochemical indices. [Result] The blood sodium （Na）, phosphorus （P）, potassium （K） and chlorine （CI） concentrations in hens under heat stress were decreased, while the activities of alanine aminotransferase （ALT）, lactate dehydrogenase （LDH） and creatine kinase （CK） were increased. These indices grad- ually returned to normal levels after the use of traditional Chinese herbal medicines. [Conclusion] The herbal medicines can relieve the adverse effects caused by heat stress to blood biochemical indices via different metabolic pathways of ions and en- zymes.
[目的]研究中药对蛋鸡在热应激条件下血液生化指标的影响,以期为临床应用提供理论和实际的依据。[方法]将100只88日龄的伊莎褐蛋鸡随机分成五组,分别设为中药方一组,中药方二组,VC对照组,热应激空白组和常温对照组。将中药方一组,中药方二组,VC对照组和热应激空白组蛋鸡置于人工制造的热应激环境下,常温对照组蛋鸡置于正常的温度条件下,分4批不同时间宰杀抽血取样,观察各组每批蛋鸡组间血液生化指标情况。[结果 ]高温时蛋鸡血钠(Na),血磷(P),血钾(K)和血氯(Cl)含量分别降低,而丙氨酸转氨酶(ALT)、乳酸脱氢酶(LDH)及肌酸激酶(CK)均上升,使用中药后,各生化指标逐渐趋于正常。[结论 ]抗热应激中药可以从各种离子和酶类不同代谢途径来缓解热应激对蛋鸡血液生理生化指标所造成的不利影响。
