热应激对绵羊行为及生理的影响
Effect of heat stress on the behavior and physiology of sheep
摘要
Abstract
Sheep belong to warm-blooded animals and their body temperature usually remain in a relative narrow physiological range to ensure the need of health,survival and reproduction.In general,the sheep can tolerance heat stress and keep their thermal equilibrium state by maintaining the balance of heat production and dissipation.The mechanism of heat adjustment in sheep is regulated by hypothalamus.Heat stress can increase body's internal heat,affect the control of heat exchange and then affect the behavior and physiology of sheep resulting in the decrease of body weight and average daily gain and affecting the health and reproduction of livestock.These effects are influenced by the breeds of sheep,the feeding model and individual variation.The effects of heat stress on the behavior and physiology of sheep were reviewed in this paper in order to provide references to reduce thermal stress damage,improve animal welfare and increase production.关键词
