Chicken is a particularly sensitive animal in light. Different light intensity and lighting time have a great effect on the growth of chickens, sexual maturity, egg production and living habits. What are the effects of light on chickens?
The following is a brief explanation.
There are two types of light sources now, one is sunlight.The ultraviolet rays in sunlight photos have a bactericidal effect. Ultraviolet rays can illuminate chicken skin to “calcium supplementation”. UV radiation can promote the formation of mineral metabolism and active vitamin D in the chicken body. Metabolic conditions.
The other is artificial light, that is, using light bulbs and other lighting tools to light up at night or darker places, instead of natural light in the darkest chicken house.
Light is very important for a closed chicken coop. Reasonable light intensity and time can promote the feeding and rest of the chicken to promote the growth and development of chickens.
1. Affect chicken diet, exercise, health, rest and development of reproductive system
For broilers, continuous lighting is generally used. Continuous lighting is mainly to increase the feeding time of chickens and promote the growth of chickens. However, because the lighting time is too long, it not only increases the cost of lighting electricity, but also stresses the chickens. The later stage will increase the death of chickens.
2. Chickens are very sensitive to light intensity
If the light intensity is too strong, in addition to affecting the normal rest of the chickens, it will also cause the overall excitement of the chickens, as well as “turning the anus” and fighting. If it is not controlled, it will even cause the chickens to pecking at the anus and feathers. Too low light intensity will be detrimental to the growth and development of chickens and delay growth.
3. Light of different colors also affects the growth and development of chickens
Yellow-orange light can delay sexual maturity of chickens, but for laying hens, yellow-orange light can improve egg-laying performance and reduce the occurrence of anal pecking; green or blue light can calm broilers and reduce Peck the anus and the feathers, which is good for catching chickens.
4. Light also has some effects on chickens at different stages
- The effect of light on chicks is mainly that light can control the development time and speed of growth and development of the first chickens. If the light is too long, the sexual maturity will be advanced, and if the light is too short, the developmental maturity will be delayed.
- Light intensity and time have a great impact on chickens in the laying period. Appropriate light intensity and reasonable light time will keep chickens in good egg-laying performance. If the light time is too short, the laying performance of the laying hens will be reduced, and if the light time is too long, the laying hens will be fatigued.
- Light for broiler chickens will also affect the slaughter time of broilers. If broilers want to produce more meat, they must eat more food. Warm light is conducive to broiler chickens drinking water and eating at night to increase feed intake. Gain weight.
