Principle of artificial lighting in chicken farms

The most indispensable for large-scale chicken farming is the cultivation equipment, battery cage for chickens, and the light of the chicken house. The light is good for broilers to find water and feed at night, so it can increase the amount of food and promote weight gain.


The effect of light time and intensity on laying hens is significant. At the appropriate intensity, the longer the illumination time, the better the egg production performance. Generally, the light time of the laying hens is maintained at 16 to 17 hours. The production performance of the hens will not reach the standard; if the hens are too long, the laying hens will easily produce egg fatigue, which will cause the chickens to lick and lose the egg production performance. The normal light intensity is 32 ~ 65 lux, too weak will make the production performance of the laying hens decline, too strong will make the laying hens fierce, barbaric, mane and other bad behavior.

At the right light intensity, the most influential part of the sexual maturity of the chicken is the time of illumination. Normal light for 12 hours can promote the normal sexual maturity of the chicken, the light is more than 12 hours, the longer the time, the faster the sexual maturity, the light is less than 12 hours, the sexual maturity of the chicken will lag. Farmers need to set the length of daily artificial lighting according to the lighting needs of different stages of the flock, the total number of hours of light per day (including natural light), the breeding period is generally not less than 8 hours, but not more than 10 hours, laying eggs The period is preferably 16 hours.


Gradually increase or decrease the illumination time: no matter whether the farmers increase or decrease the number of hours of illumination when performing illumination, they cannot suddenly increase or decrease dramatically. Note that each increase should not exceed 1 hour. In addition, it should be noted that the illumination time during the breeding period can only be shortened and cannot be extended. The egg production period is reversed and can only be extended
and cannot be shortened. Lighting program: Farmers must have a fixed lighting program
Once the lighting program is determined, it must be strictly observed and cannot be changed at will.

Controlling the lighting time: Farmers should pay attention to the appropriate control of the hours of light when the quality of the chicken population or nutritional status is poor and the temperature is extremely low. If you use 14 hours of light to reduce the physical consumption of the laying hens, so that they have a short rest in poultry cage equipment, the next year when the warmth, the egg production rate rebounds faster and the peak is higher.
