Abstract

More energy-efficient, durable, affordable, and dimmable light-emitting diode (LED) lights are finding applications in poultry production. However, data are lacking on controlled comparative studies concerning the impact of such lights during the pullet rearing and subsequent laying phase. This study evaluated two types of poultry-specific LED light (PS-LED) vs. fluorescent light (FL) with regards to their effects on hen laying performance. A total of 432 Hy-Line W-36 laying hens were tested in two batches using four environmental chambers (nine cages per chamber and 6 birds per cage) from 17 to 41 weeks of age (WOA). Dim-to-red PS-LED and warm-white FL were used in the laying phase. The hens had been reared under a dim-to-blue PS-LED or a warm-white FL from 1 to 16 WOA. The measured performance variables included 1) timing of sexual maturity, 2) egg production performance, 3) egg quality, and 4) egg yolk cholesterol. Results showed that the two types of light used during the laying phase had comparable performance responses for all response parameters (P > 0.05) with a few exceptions. Specifically, eggs laid from hens in the PS-LED treatment had lower shell thickness (P = 0.01) and strength (P = 0.03) than those in the FL treatment at 41 WOA. The two types of light used during the rearing phase did not influence the 17 to 41 WOA laying performance, except that hens reared under the PS-LED laid eggs with lower shell thickness (P = 0.02) at 32 WOA as compared to hens reared under the FL. This study demonstrates that the emerging poultry-specific LED lights yield comparable production performance and egg quality of W-36 laying hens to the traditional fluorescent lights.

摘要

更节能、更耐用、更经济实惠且可调光的发光二极管 (LED) 灯正在被应用于家禽生产中。然而,关于这些灯在育雏和随后的产蛋阶段的影响,缺乏对照研究的数据。本研究评估了两种特定于家禽的 LED 灯 (PS-LED) 与荧光灯 (FL) 对母鸡产蛋性能的影响。总共使用四个环境室(每个室有 9 个笼子,每个笼子有 6 只鸡),对 432 只海兰 W-36 产蛋母鸡进行了两批测试,从 17 到 41 周龄(WOA)。在产蛋阶段使用了 dim-to-red PS-LED 和 warm-white FL。母鸡在 1 到 16 WOA 期间被饲养在 dim-to-blue PS-LED 或 warm-white FL 下。测量的性能变量包括 1) 性成熟时间,2) 产蛋性能,3) 蛋品质,和 4) 蛋黄胆固醇。结果表明,在产蛋阶段使用的两种类型的光在所有响应参数上具有可比的性能响应(P > 0.05),但也有一些例外。具体来说,在 41 WOA 时,PS-LED 处理组母鸡产下的鸡蛋蛋壳厚度(P = 0.01)和强度(P = 0.03)较低。在育雏阶段使用的两种光并没有影响 17 到 41 WOA 的产蛋性能,除了在 PS-LED 下饲养的母鸡在 32 WOA 时产下的鸡蛋蛋壳厚度较低(P = 0.02),与在 FL 下饲养的母鸡相比。本研究表明,新兴的特定于家禽的 LED 灯与传统荧光灯相比,可产生相当的生产性能和 W-36 产蛋母鸡的蛋品质。
