An 18-week experiment was conducted to investigate the effects of changing from incandescent to fluorescent lighting on egg production, egg weight, fertility, and hatchability of end of lay broiler breeders housed in an open-sided house. Forty-eight-week-old Cobb feather-sexed broiler breeders were housed, 30 females and 3 males per pen, in a total of 28 pens. Incandescent lights had been used previously, so pens were randomly assigned to either fluorescent or incandescent lights giving 20 lx of light at bird level. Lights used were 60 W incandescent and 22 W fluorescent cool-white circular. Body weight and egg production were measured weekly, and fertility, hatchability, and egg weight were determined monthly from 48 to 65 weeks of age. No significant treatment effects were observed on body weight, fertility, hatchability, or egg weight. A significant reduction in egg production was observed with fluorescent lighting from Weeks 58 to 65. The reduced egg production indicated it was detrimental to change from incandescent to cool-white fluorescent lighting.
进行了一项为期18周的试验，以研究在开放式鸡舍中饲养的产蛋后期肉种鸡从白炽灯照明改为荧光灯照明对产蛋量、蛋重、受精率和孵化率的影响。48周龄的科宝羽速鉴别肉种鸡，每栏饲养30只母鸡和3只公鸡，共28栏。此前使用的是白炽灯，因此将鸡栏随机分配到荧光灯或白炽灯组，使鸡只水平光照强度为20勒克斯。使用的灯为60瓦白炽灯和22瓦荧光冷白色圆形灯。每周测量体重和产蛋量，在48至65周龄期间每月测定受精率、孵化率和蛋重。在体重、受精率、孵化率或蛋重方面未观察到显著的处理效应。在第58至65周期间，荧光灯照明下产蛋量显著下降。产蛋量下降表明从白炽灯改为冷白色荧光灯是有害的。
