摘要
奶牛是一种耐寒怕热的动物,尤其是产奶期体内产热量大,且奶牛调节体温的能力有限,因此在众多的应激因素中,高温环境对奶牛的应激影响尤为突出。实践证明,适宜奶牛生活的温度范围在10-21℃之间,超过适宜温度时,奶牛体温开始上升,容易引起热应激。在我国,在饲料中添加中草药添加剂来防治热应激的研究颇多,本文对近年来使用中草药防治奶牛热应激的研究进行综述,以供参考。
Dairy cattle have a certain cold-foree, but the heat intolerance. Especially when it＇s in milk, the dairy cattle produeed more heat, along with its heal intolerance, so heal stress is one of the most dangerous stress responses. Practices show that the temperature range suitable for cattle is 10-21 ℃. The body temperature of dairy cattle will rise when air temperature is above the temperature range, and easily get rise to heat stress. In China, there are many of researehes for using herbs to control heat stress response.This article made a summary for the researches of using Chinese herbs to prevent and cure dairy cattle heat stress response in recent years for reference.
