Two trials were completed that examined the effects of light intensity on poult performance, adrenal weight, and ocular size during the first 2 weeks after hatching. In both trials the treatments started on the day of hatching and consisted of 23 hr of light per day of either 1.1, 11, 110, or 220 lx intensity from incandescent bulbs. A light intensity of 1.1 lx, but not 11, 110, or 220 lx, had an adverse effect on poult performance as indicated by significantly smaller body weights, reduced feed intake, and increased mortality in both trials. In addition, the poults in the 1.1 lx treatment group had significantly enlarged eyes in both trials and significantly greater adrenal weights in Trial 2 than the other treatment groups. It was concluded that low light intensity of 1.1 lx resulted in poor poult performance, and this was accompanied by an altered morphology of the eyes and the adrenal gland.
进行了两项试验，研究孵化后头两周光照强度对雏禽生长性能、肾上腺重量和眼部大小的影响。在两项试验中，处理均从孵化当天开始，由白炽灯泡提供的每天23小时光照组成，光照强度分别为1.1、11、110或220勒克斯。两项试验均表明，1.1勒克斯的光照强度对雏禽生长性能有不利影响，表现为体重显著减轻、采食量减少和死亡率增加，而11、110或220勒克斯则没有这种影响。此外，在两项试验中，1.1勒克斯处理组的雏禽眼睛显著增大，在试验2中，其肾上腺重量也显著高于其他处理组。研究得出结论，1.1勒克斯的低光照强度导致雏禽生长性能不佳，并伴有眼睛和肾上腺形态的改变。
