“14+1 h”光照程序对褐壳蛋种鸡生产性能的影响

Effect of “14+1 h” Lighting Program on Performance of Brown Shell Breeding Hens

试验选用19536只同一批海兰褐父母代蛋种鸡,随机分为两组。对照组采用16h传统光照程序,试验组采用"14+1 h"光照程序,分析生产性能、繁殖性能和蛋品质的变化。结果表明,与16 h传统光照程序相比,"14+1 h"光照程序不会降低产蛋率,不会增加破蛋率,提高了鸡的采食量,对夏季保障采食量有利;不会降低种蛋合格率和受精率,可显著提高蛋重和蛋壳重,对其余蛋品质指标无显著影响。同时,"14+1 h"的光照程序减少了1 h光照,达到了节能的效果。

The experimental animals were 19 536 Hy-Line parent stock,which were same age and same group. The layers were divided into a control group and an experimental group. The control group made use of traditional lighting program,and ＂14＋1 h＂ lighting program was for the experimental group. The results showed,comparing with 16 h lighting program,＂14＋l h＂ lighting program didn＇t decrease laying rate,could increase egg broken rate and feed consumption, which was good to guarantee the feed consumption at summer, and decrease hatching egg quality rate and fertility rate, increase egg weight and egg shell weight significantly. What＇s more,the ＂14＋1 h＂ lighting program could save energy because of lessened 1 h.
