摘　　要：高温环境是影响家禽生产的一个重要因素,高温环境下家禽采食量降低,肉鸡生长速度减慢,蛋鸡产蛋率、蛋重及体重下降。高温环境影响家禽生产性能并非全部由于采食量下降引起的,即使在相同采食量的条件下,高温环境仍显著降低家禽的生产性能。本文针对高温环境对家禽营养物质消化代谢以及消化酶活性、肠道结构、饲粮排空速度等方面的影响进行归纳总结,为进一步了解高温环境对家禽消化吸收功能的影响及其营养调控提供科学依据。High ambient temperature is an important factor that affects poultry production,which decreases the feed intake of poultry,induces the deleterious effect on growth rate of broilers and egg production,egg weight and body weight in laying hens.However,this negative effect of heat stress on growth rate and production is not all due to reduced feed intake,production performance still significantly reduces under the high environment temperature even in the same condition of feed intake.This paper mainly reviewed the effect of high temperature on nutrition digestibility,metabolic energy values of diet,digestive enzyme activity,feed passage rate and gut structure in poultry to provide scientific basis for understanding the effects of high temperature on digestion and absorption function of poultry and its nutritional regulation.
