摘　　要：在各种应激因子中,热应激对泌乳母猪的影响最大。泌乳母猪发生热应激后会通过各种机制来保持体内的热平衡,比如降低食欲、重新分布血流以及改变内分泌状态,泌乳母猪的体重减轻程度加大,母猪泌乳量和仔猪生长率降低,母猪的繁殖性能也会受到影响。本文从热应激对泌乳母猪的生产性能、乳成分、生理指标、血液生化指标及催乳激素等方面的影响进行了论述,为目前的养猪生产提供参考。Among the stress factors, heat stress had the greatest impact on lactating sows. Lactating sows subjected to heat stress will keep the body heat balance through a variety of mechanisms, such as reducing appetite, redistribution of blood flow and the change of endocrine status, increasing the loss of sow＇s weight during lactation, reducing milk yield and the growth rate of piglets, which affect the reproductive performance of sows. The effects of heat stress on lactating sow＇s performance, milk composition, physiological indexes, biochemical indexes and prolactin were discussed in this article, which will provide reference for the pig production at present.
