【摘要】 本文主要根据最近10年有关鸡的环境生理学的研究报道综述而成。内容包括鸡热调节的生物学特性,环境温度、湿度和光照等对鸡的体温和热调节、心率和血压、血液成分和内分泌机能等的影响。阐明急性热应激引起热衰竭的原因及其有关因素.讨论鸡的水消耗和缺水反应.论述鸡对气候的服习和驯化过程以及耐热和耐寒性能.它为高密度、集约化养禽业制订合理的环境控制措施提供理论依据。更多还原

【Abstract】 This review is mainly based on research papers on environmental physiologyin chickens,a majority of which were publised in the last decade.It intro-duces briefly the thermoregulation characteristics of chichens and discussesthe effects of environmental temperature,humidity and light on body tempera-ture and its regulation,energy metabolism,and heat production,heart rate andblood pressure,blood composition and endocrine functions of chickens.Thereview explains the cause and its associate factors of heat exhaustion resultingfrom acute heat stress,and deals with water consumption of chickens andtheir response to the deprivation of water.The procceses of acclimation andacclimatization,and heat and cold tolerance of chickens are elucidated.Thispaper provides a basic principle of environmental control for high density andintensive poultry production.更多还原
