光色对蛋型雏鸡影响的试验研究

本文系首次在国内使用八种市售色灯对0～40龄白来航雏鸡3600只进行色光对雏鸡影响的试验性研究。共观察了雏鸡体重增长、死亡率、抑制与兴奋、敏感性、啄癖等项。结果表明,色光灯对0～40日龄白来航雏鸡的良性反应顺序如下:红光灯>橙光灯>兰光灯>白炽灯,白炽灯+紫外灯和绿光灯>日光灯>红外线灯。其中,红光灯积分最高,为27分;红外线灯积分最低,为7分(满分32分)

THE RAISING EFFECT OF DIFFERENT COLOR LAMPS ON LAYERS

In this article eight different color lamps bought from the market were used to test the raising effect of layers. There were 3, 600 white leghorn layers (from o to 40 days old) to be divided into eight groups to receive eight different treatments with eight different color lamps . The items to be examined were: gain of body weight, death rate, inhibition or excitation, susceptibility and cannibalism. The testing results showed that the best treatment is under the light of red lamp and the worst one is the infrared ray lamp. As the full score is 32 points, layers to be raised under the red lamp got 27 points and those under the infrared ray lamp only 7 points. Th order of the score under the different color lamps from the best to the worst are red lamp, orange lamp, bluelamp , indandescent lamp, incandescent plus ultraviolet lamps, fluorescent lamp and infrared ray lamp.
