LED灯光照对笼养蛋鸡生长发育和生产性能的影响

LED灯具有耗电量低、使用寿命长、高亮度低发热、制作材料无毒环保等优点。本试验把同批白来航种鸡随机分为2栋,分别采用LED灯和白炽灯作为照明光源研究其对笼养蛋鸡生长发育和生产性能的影响。结果显示,在育雏育成阶段,使用LED灯具可提高鸡群均匀度,减少耗料量和死淘率,对体重的影响不明显。在产蛋阶段,使用LED灯可减少鸡群死淘率,对蛋重、产蛋率、破蛋率和种蛋率影响不明显。30周龄血液生化指标无显著差异。表明在蛋鸡养殖生产中使用LED灯作为照明光源安全有效。

Effect of LED Lighting on Growth and Production Performance of Caged Layers

LED lamps have many advantages,such as low power consumption,long service life,high brightness and low fever,avirulent,pro-environment and so on. LED lamps and filament lamps were used as lighting source in this experiment,to study the effects of LED lighting on growth and production performance of caged layers. The results showed that in brooding stage,using LED lamps could increase the uniformity of chicken group,decrease feed consumption rate and mortality,but the influence of the weight was not obvious. In laying cycle,using LED lamps could decrease mortality rate of chicken group,but the effect to egg size,egg rate,broken egg rate and hatching egg rate was not obvious (P<0.05). The influence to blood biochemical parametes of layer at 30 weeks age were not obvious. The results suggested that using LED lamps as lighting source was safe and effective in practical production of caged layers.
