摘要
随着规模化集约化养殖方式的发展,热应激成为制约我国家禽养殖产业进一步发展的重大因素之一。热应激引起家禽采食量下降、生长速度减慢、饲料利用率降低,最终导致家禽生产性能和免疫功能的下降和死亡率的增加,给家禽产业带来巨大的经济损失,同时全球变暖使得越来越多的研究聚焦于如何缓解动物的热应激反应和减少其对动物生产的影响。硒代蛋氨酸(Se Met)具有抗氧化、增强免疫力和抵抗应激等作用,可缓解氧化应激,提高家禽的生产性能。因此,文章对Se Met的吸收代谢、生物学功能以及缓解家禽热应激的可能作用机制进行综述,旨在为Se Met在家禽热应激上的应用研究奠定基础。
With the development of the large-scale intensive aquaculture system,heat stress has become a major factor that restricts the further development of the poultry industry in our country.Heat stress causes the decrease of feed intake,growth rate and feed utilization rate of poultry,and eventually leads to the decline of poultry performance and immune function and the increase of mortality,bringing huge economic losses to the poultry industry.Meanwhile,global warming makes more and more studies focus on how to alleviate the heat stress response of animals and reduce its impact on animal production.Sele⁃nomethionine(Se Met)can relieve oxidative stress and improve the performance of poultry.Therefore,the absorption and metabolism,biological functions of Se Met and the possible mechanism of alleviating heat stress in poultry were reviewed in this paper,aiming to lay a foundation for the application of Se Met in heat stress in poultry.
