The low uniformity in light distribution provided by conventional lighting systems installed in laying poultry can compromise the productive performance and egg quality of laying hens. Thus, the aim of the current study is to evaluate the effect of a linear lighting system with light-emitting diode (LED strip) on the productive performance and egg quality of laying hens, by comparing it to the conventional LED lamp lighting system. The study used Hy-Line Brown hens from a commercial production unit. Hen-day egg production (%), mortality rate (%), egg weight (g), albumen height (mm), Haugh unit, eggshell thickness, eggshell strength, and thermal-environment conditions were evaluated from the 19th to the 48th wk of age. The results have shown that LED strips were capable of improving egg production (P < 0.05) in comparison to LED lamps. Egg quality was not affected (P > 0.05) by the evaluated lighting systems throughout the experimental period. Results of the current study indicate that the homogeneous illuminance distribution provided by the linear LED strip lighting system at different cage floors improved egg production in comparison to the conventional LED lamp lighting system.

线性照明系统对蛋鸡生产性能和蛋品质的影响。

安装在蛋鸡上的常规照明系统所提供的光线分布不均会降低蛋鸡的生产性能和蛋品质。因此，本研究的目的是通过与传统的LED灯照明系统进行比较，评估带有发光二极管（LED灯条）的线性照明系统对蛋鸡生产性能和蛋品质的影响。该研究使用了来自商业生产单位的Hy-Line Brown母鸡。从第19周到第48周评估母鸡的产蛋量（％），死亡率（％），蛋重（g），蛋清高度（mm），霍夫单位，蛋壳厚度，蛋壳强度和热环境条件年龄。结果表明，与LED灯相比，LED灯条能够提高产蛋量（P <0.05）。在整个实验期间，受评估的照明系统均不影响鸡蛋质量（P> 0.05）。当前的研究结果表明，与传统的LED灯照明系统相比，线性LED灯带照明系统在不同的笼形地板上提供的均匀照度分布提高了产蛋量。
