| 摘 要： | 本试验利用3126只美·爱拔益加AA肉用仔鸡,在自行设计的间歇光照制的环境中,观测不同光照日周期及光照强度对21～56日龄肉用仔鸡生产性能的影响。试验结果表明:在存活率,饲料利用率及出栏群平均个体重三方面,采用间歇光照制及光照强度为5勒克司的第一、二试验组优于连续24小时光照日周期及光照强度2。勒克司的对照组。其中,采用光照日周期为1L:3D,5勒克司光照管理程序的第一试验组优于光照日周期为1L:1.5D、5勒克司光照管理程序的第二组。

| Abstract: | AA broiler chickens(3126) were used in this experiment to determine the effects of the different lighting cycles and light intensity on the productivity of the 20-59 days old broiler chickens in the intermittent lighting environment. The experiment results indicated that the average body weight gain, feed conversion ratio and survival ratio of the experiment groups 1 and 2 treated with the intermittent lighting regimens and light intensity of 5Lux were better than those of the control groups treated with the 24 h nonstop lighting regimen and light intensity over 25 Lux. The experiment group 1 treated with the 1 L : 3 D lightingmanagement programme was better than the experiment group 2 treated with the 1 L :1.5D lighting management programme. |
