Abstract

The current work investigated the influences of different light sources on growth performance, carcass characteristics, blood biochemicals, physiological status and health aspects. One hundred and twenty growing California rabbits were assigned into four empirical collections in an experiment of completely randomized design. Rabbits of the first collection were reared under incandescent light bulbs (control), while the second, third and fourth collections were reared under fluorescent, saving light and LED light bulbs, respectively. The results indicated that rabbits reared under incandescent and LED had the heaviest body weight at 16-weeks-old. Rabbits reared under LED recorded the greatest gain during 14–16 weeks of age and 6–16 weeks of age. The lowest feed conversion ratio was observed in rabbits reared under LED lighting, during 14–16 weeks of age, and during the whole period without significant variations. Fat percentage (%) was low in rabbits exposed to fluorescent and LED. Rabbits grown under LED showed the lowest albumin/globulin and the highest glucose concentration. Rabbits kept under LED showed the lowest rectal temperature, mortality and health risks %. Conclusively, LED lighting source might be appropriate for alteration of incandescent and fluorescent light sources in rabbit farms to improve growth performance without compromising rabbit's carcass and welfare.

摘要

目前的工作调查了不同光源对生长性能、胴体特征、血液生化、生理状态和健康方面的影响。在完全随机设计的实验中，120 只生长中的加利福尼亚兔被分配到四个经验集合中。第一次收集的兔子在白炽灯泡（对照）下饲养，而第二次、第三次和第四次收集的兔子分别在荧光灯、节能灯和 LED 灯泡下饲养。结果表明，在白炽灯和 LED 灯下饲养的兔子在 16 周龄时体重最重。在 LED 下饲养的兔子在 14-16 周龄和 6-16 周龄期间收获最大。在 LED 照明下饲养的兔子中观察到最低的饲料转化率，在 14-16 周龄期间，并且在整个期间没有显着变化。暴露于荧光灯和 LED 的兔子的脂肪百分比 (%) 较低。在 LED 下生长的兔子显示出最低的白蛋白/球蛋白和最高的葡萄糖浓度。在 LED 下饲养的兔子的直肠温度、死亡率和健康风险百分比最低。最后，LED 光源可能适用于改变兔场中的白炽灯和荧光灯源，以提高生长性能而不损害兔子的胴体和福利。死亡率和健康风险%。最后，LED 光源可能适用于改变兔场中的白炽灯和荧光灯源，以提高生长性能而不损害兔子的胴体和福利。死亡率和健康风险%。最后，LED 光源可能适用于改变兔场中的白炽灯和荧光灯源，以提高生长性能而不损害兔子的胴体和福利。
