Illumination conditions of environmental factors for laying hens

Illumination is one of the indispensable environmental factors in the process of laying hens. Light promotes the growth and development of chickens, and has a decisive stimulating effect on the reproduction of chickens, that is, the sexual maturity, ovulation and egg production of chickens.

The mechanism of light action. Birds are generally considered to have two photoreceptors, one being the retinal receptor, the eye. The other is located in the hypothalamus. The hypothalamus is stimulated by light changes to secrete gonadotropin-releasing hormone. This hormone reaches the anterior pituitary through the pituitary portal system, causing the secretion of follicle stimulating hormone and ovulation hormone to promote bleb development and ovulation. So how do you control the lighting conditions? Used chicken cages sale

According to the chicken's response to the light color, the environmental control of the house can be red light during the breeding period, green light during the egg laying period, and incandescent light in the open house. Since natural light is a composite white light that is a mixture of light of different wavelengths, an incandescent light bulb or a fluorescent light is generally used as a supplementary light source. Compared with fluorescent lamps, incandescent lamps produce more heat, have lower luminous efficiency, and consume more power. But the price is cheap, the investment is small, and it is easy to start, so both light sources can be used. In the long run, fluorescent lamps will replace incandescent lamps.

Too strong or too weak will have adverse consequences. Too much light is not only wasting energy. Moreover, chickens appear nervous, easy to stun, and have a large amount of activity, which consumes energy and is prone to fighting and convulsions. The light is too weak, affecting feeding and drinking. Not stimulating. Affect the amount of egg production.
In order to make the illumination uniform, the distance between the general light sources is 1 to 1.5 times of its height, and the bulbs of different columns adopt the plum blossom distribution. Note whether the illumination intensity of the lower layer of the chicken cage meets the requirements of the chicken. The use of a lampshade increases the light intensity by about 45% compared to a lampshade. Light bulbs and lamp covers are prone to dirt due to the dust and small insects in the house. Need to wipe frequently and replace the bad bulbs in time to maintain sufficient brightness.air flow chicken coops
