摘　　要：鸡没有牙齿,胃肠分泌消化液较少,加上饲料在消化道内停留时间短,相对其他动物,鸡对饲料的消化和吸收能力较差,再加上鸡体散热能力较差,在外界环境温度升高时,鸡的采食量明显减少,同时鸡的采食量还会受饲料营养、品种、日龄、活动量、繁殖阶段、饲料形状和气味等因素的影响。如饲料营养浓度较高、饲料直径较大等情况下,鸡的采食量增加;鸡日龄或体重越大、繁殖能力越强,采食量也会越多。非病理性因素发生改变后,可引起鸡采食量和摄入机体的营养成分发生变化,如果无法满足机体生长或生产的需要,势必降低鸡饲料转化率、以及产肉或产蛋水平。鸡体特殊的生理特点决定着其采食量会受到各种因素的影响,该文对鸡采食量的非病理因素进行阐述,并提出合理的解决方案,以便更加科学地配置饲料配方。Chickens have no teeth,and the gastrointestinal secretion of digestive juice is less.In addition,the feed stays in the digestive tract for a short time.Compared with other animals,chickens have poor digestion and absorption capacity of feed.In addition,chickens have poor heat dissipation capacity.When the external environment temperature rises,the feed intake of chickens decreases signiffcantly.At the same time,the feed intake of chickens is also affected by feed nutrition,variety,age,activity,reproductive stage The influence of feed shape and smell.For example,when the feed nutrient concentration is high and the feed diameter is large,the feed intake of chickens increases,The bigger the age or weight of the chicken,the stronger the reproductive capacity,the more feed intake will be.The change of non pathological factors can cause changes in the feed intake and the nutrient composition of the body.If it cannot meet the needs of the body growth or production,it is bound to reduce the feed conversion rate and the level of meat or egg production.The special physiological characteristics of the chicken determine that its feed intake will be affected by various factors.This paper describes the non pathological factors of the chicken feed intake,and puts forward a reasonable solution,so as to conffgure the feed formula more scientiffcally.
