【摘要】：为探讨荷斯坦奶牛抗热应激最佳方案,选用甘肃某奶牛场部分出现热应激症状的奶牛,将其分为治疗1组与治疗2组,另选择未发生应激的奶牛10头作为正常对照组,其中正常对照组仅采用喷淋和风扇结合方式给奶牛降温,治疗1组在此基础上采用烟酰胺干预,治疗2组采用中草药制剂干预,比较分析各组环境温度、湿度、生理指标、生产性能指标、血液中激素、抗氧化能力及免疫相关指标。与正常对照组相比,治疗1组与治疗2组产奶量、血液中激素、抗氧化能力及免疫指标均在干预前发生显著变化,且经2种方法干预后均出现比较明显恢复(P0.05)。与治疗1组干预后相比较,治疗2组经干预后,产奶量、血清中皮质醇(COR)、三碘甲腺原氨酸(T3)、胰岛素(INS)、热休克蛋白70(Hsp70)、免疫球蛋白A(IgA)、免疫球蛋白G(IgG)、肿瘤坏死因子α(TNF-α)、超氧化物歧化酶(SOD)、谷胱甘肽过氧化物酶(GSH-Px)活性、总抗氧化能力(T-AOC)和丙二醛(MDA)含量恢复显著(P0.05)。结果表明,中草药制剂可以显著改善热应激奶牛环境温度、湿度、产奶量、激素水平、抗氧化及免疫能力。
[Abstract]:In order to study the best scheme of resisting heat stress in Holstein cows, the cows with partial heat stress symptoms in a dairy farm in Gansu Province were divided into two groups: treatment group 1 and treatment group 2, and 10 cows without stress as normal control group.The normal control group only used spray and fan combination to cool the cows, the treatment group 1 was treated with nicotinamide on this basis, and the treatment group 2 was treated with Chinese herbal medicine. The environmental temperature, humidity and physiological indexes were compared and analyzed.Production performance, blood hormones, antioxidant capacity and immune-related indicators.Compared with the normal control group, the milk yield, blood hormones, antioxidant capacity and immune indexes of the treatment group 1 and the treatment group were significantly changed before the intervention, and the recovery of P0.05 was obvious after the intervention of the two methods.Compared with the treatment group 1 after intervention, the milk yield of the treatment group 2 after intervention,Total antioxidant capacity (T-AOC) and malondialdehyde (MDAs) contents recovered significantly (P 0.05).The results showed that Chinese herbal medicine could significantly improve the environmental temperature, humidity, milk yield, hormone level, antioxidation and immune ability of heat stress cows.
