Some people say that in practice the use of chicken coop special lights has no effect, in fact, chickens are very sensitive to light, different colors of lights have a great effect on chickens, in the development of chicken industry in the application of color, can significantly improve the economic benefits of chicken breeding. Chickens can see light with a wavelength of 400-700 nm, which is particularly sensitive to red, orange and yellow light.
Yellow light reduces feed returns, delays sexual maturity, increases egg weight, reduces egg production, and increases pecking.
Red light can improve egg production. The laying hen coop is illuminated with red lights, which can increase the egg production rate by 10%. Moreover, chickens tend to be quiet under red light to prevent chicken pecking, and it is reported that painting the door and window glass of the chicken coop red can reduce the occurrence of chicken pecking. The ripening period is slightly later, the egg production is slightly increased, but the fertilization rate is lower.
Green light can increase growth rates. Green light and blue light promote sexual maturation and make chickens gain weight quickly. American scientists have found that green light can speed up the growth of chickens and improve their disease resistance. Studies have proved that broiler chickens are illuminated with 15 watts of 5-6 lux green fluorescent lamps, 1 hour of light and 3 hours of dark crossing, which can significantly increase the content of carotene, VA and VB in the liver, gain weight quickly and have high benefits. And it can also improve the fertilization rate of roosters, green light lighting or blue light lighting have the effect of improving the fertilization rate of breeding roosters.
Gray can improve egg production rate, American scientists have found that making the egg nest of laying hens gray can increase the egg production rate of chickens by 3.5%.
