摘 要：
在７日龄时，肉用仔鸡由接近全日制光照（２３ｈ光照，１ｈ黑暗）改变为１ｈ光照，３ｈ黑暗的短周期间歇光照。结果表明，短周期间歇光照的肉仔鸡饲料报酬和饲料利用率提高。氮平衡试验表明，增加肉用仔鸡的光周期，粪氮分泌量减少，饲料氮在鸡体内的沉积增加，而饲料氮的摄入量并未增加，因而使得饲料氮的利用率得到提高。

摘 要：
At seven day-age,the broilers were changed from continous lighting schedule(23 hours light,1 hour dark)to intermittent lighting schdule(1 hour light,3 hours dark).The results show that the feed reward and the using of the feed were increased photoperiod.The experiment of the nitrogen balance shown,to increase the broilers lighting photoperiod,the secreting of the fecal nitrogen are increased and the depositing of feed nitrogen in the broiler are increased.Whereas,the feed of the feed nitrogen wasn't increased.So using of the feed nitrogen efficiency was increased.
