热应激畜禽的营养调控

夏季高温环境下,畜禽极易发生热应激。畜禽发生热应激后其生产性能降低,严重影响养殖效益。营养调控措施是根据畜禽的发育规律,通过调配适宜的营养成分和含量,降低热应激对畜禽的生长过程的影响,使畜禽养殖朝着健康、绿色、持续、高效的方向发展。从调节电解质、矿物质、维生素等营养调控的角度综述了热应激防控的最新研究进展,以期为防控热应激和寻找新的措施、最大限度地降低畜牧业生产损失提供有益的思路。

Nutritional Regulation of Heat-stressed Livestock and Poultry

Under high temperature environment in summer,livestock and poultry are vulnerable to heat stress.After they have suffered heat stress,their production performance is reduced,which seriously affects their breeding efficiency.Based on the development law of livestock and poultry,the nutrition regulation measures aim to reduce the impact of heat stress on the growth process of livestock and poultry via appropriately allocating the nutrient composition and content,and leading the development of livestock and poultry breeding to the health,green,sustainable and high-efficient direction.This article reviews the latest advances in the prevention and control of heat stress from the perspective of regulation of electrolytes,minerals,vitamins and other nutrients,in hoping to provide useful ideas to prevent and control the heat stress in livestock and poultry and to find new measures to minimize the economic losses of animal husbandry production.
