新型LED光源对蛋鸡生长发育影响的研究进展

Review on Effect of LED Light on Growth and Development of Layers

基于禽类特殊的视觉系统及现阶段主要采用的密闭式禽舍建筑形式,人工光照管理在蛋鸡生产中的重要性愈发凸显。新型LED灯以其节能、高效、单色性佳、可进行智能化调控等诸多优点被广泛应用于蛋鸡生产中。文章概述了近年来传统光源及LED光色、光照度及光照周期等因素对蛋鸡生长发育(采食量、体重及饲料转换率)、生产性能(开产日龄、产蛋量及蛋品质)、行为活动(觅食、采食、梳羽、休息及啄癖)等方面产生的影响,对比分析传统光源和LED光源存在的差异,回顾了LED光源智能化调控技术在畜禽舍照明领域内的发展现状,指出LED灯在蛋鸡生产中的应用潜力和方向,以期为日后的研究提供更多的突破思路。

The importance of light in the production of layers is much more significantly,based on the special visual system of birds and the closed building form.LED has been widely used in layers production for its advantages,such as energy saving,high efficiency,good monochromatic and intelligent control.A detailed literature review of different physiological and behavioral effects of different light resources on laying hens focused on the light intensity,photoperiod and light color were undertaken.On the physiological aspect,reference was made on the effects of light（light intensity,light color and photoperiod） on the growth and development（feed intake,body weight and feed conversion ratio）,production performance（the age of first egg,the number of eggs and the egg qualities） and behaviors（foraging,feeding,fluming,resting and feather pecking）.Furthermore,this paper also analyzed the differences between LED lamps and traditional light,reviews the intelligent control technology of LED light that used in poultry houses,pointed out the application potential of LED in the production of poultry,to provide more research directions in the future.
