Large White turkey hens were conditioned with 5 lx of white or red incandescent light from 20 to 32 weeks of age. Hens from both of these groups were given white or red incandescent light at two intensities (approximately 85 and 160 lx) during a 20-week breeder period. Feed consumption was greatest for hens no white light during the prebreeder period (P less than or equal to .01), but hens on red light consumed the greatest amount of feed during the breeder period. The only consistent finding concerning egg production was the hens exposed to high intensity (160 lx) white light, regardless of whether the prebreeder light was white or red, had the poorest egg production (P less than or equal to .01). It is concluded that red light during the prebreeder or breeder periods is not beneficial for egg production over that achieved with low intensity white incandescent light, and that bright white incandescent light is deleterious to egg production.
大白火鸡母鸡在20至32周龄时接受5勒克斯的白色或红色白炽灯光照进行环境适应。这两组母鸡在20周的产蛋期内都接受两种强度（约85勒克斯和160勒克斯）的白色或红色白炽灯光照。在繁殖前期不接受白光的母鸡采食量最大（P≤0.01），但在产蛋期接受红光的母鸡采食量最大。关于产蛋量唯一一致的发现是，无论繁殖前期光照是白色还是红色，暴露在高强度（160勒克斯）白光下的母鸡产蛋量最差（P≤0.01）。得出的结论是，在繁殖前期或产蛋期，红光对产蛋量的益处并不高于低强度白色白炽灯光照下的产蛋量，而且明亮的白色白炽灯光照对产蛋量有害。
