摘要
论述了热应激对动物某些理化指标及生产性能的影响,热应激降低动物生产性能,持续热应激导致动物死亡率升高。指出热应激导致动物采食量减少是影响动物生产性能的主要因素,而体内理化指标的变化对动物的生产性能也产生十分重要的影响。提出生产中要进一步搞清楚热应激的作用机理,从根本上解决热应激对动物的危害。
The influence of heat stress on animals' physiological - biochemical index and production capacity are discussed. Heat stress can reduce the production capacity of some animals and continuous heat stress can lead to the death rate increase. Animals' amount of forage reducing made by heat stress is the most important reason affecting their production capacity. The changes of internal physiological-biochemical index also have deep influence on the animals' production capacity. In order to eliminate the harm of heat stress to animals the mechanism of heat stress must be clarified.
