Chicken is a kind of animal that is particularly sensitive to light. Different light intensity and light time have a great effect on the growth, sexual maturity, egg laying and living habits of chicken. What are the effects of light on chickens? Here are a few points for you.
At present, there are two kinds of light sources, one is sunlight. Everyone knows that ultraviolet rays in sunlight have bactericidal effect. Ultraviolet rays can irradiate chicken skin with "calcium supplement" effect. Ultraviolet radiation can promote mineral metabolism and active vitamin D formation in chicken body, and active vitamin D is a necessary condition to ensure normal calcium metabolism.
Therefore, continuous and effective light can regulate the balance of calcium and phosphorus in the body to prevent rickets and other bone diseases. However, it should be noted that too strong ultraviolet rays also have disadvantages, which can cause some skin diseases.
The other is artificial light, that is, the use of light bulbs and other lighting tools at night or darker places, in the dark light of the chicken house instead of natural light. Light is very important for closed chicken coop, reasonable light intensity and time can promote chicken feeding and rest to promote the growth and development of chicken.
1. light mainly affects the diet, exercise, health, rest and the development of the reproductive system of chickens.
2. chickens are very sensitive to light intensity
If the light intensity is too strong, it will not only affect the normal rest of the chickens, but also cause the excitement of the chickens as a whole, as well as "turning over the anus" and fighting. If it is not controlled, it will even cause chickens to peck anus and feather. Low light intensity will be detrimental to the growth and development of chickens and delay growth.
3. different colors of light also have an effect on the growth and development of chickens
Yellow-orange light can delay the sexual maturity of chickens, but for laying hens, yellow-orange light can improve egg production performance and reduce the occurrence of anal pecking. Green light can make broilers gain weight faster and reduce anal pecking, but also reduce egg production.
4. light also has some effects on chickens at different stages.
1. The effect of light on chicks is mainly that light can control the development time and the speed of growth and development of the first chicken. If the light is too long, the sexual maturity will be advanced, and if the light is too short, the sexual maturity will be delayed.
2. The light intensity and time have a great influence on the chickens in the laying period. Appropriate care intensity and reasonable light time will make the chickens maintain good laying performance. Light time is too short to cause the laying performance of laying hens will be low.
