The modern chicken industry has four pillars: water, materials, ventilation, and light. Although the light is called one of the four pillars of the chicken industry. But it has not received enough attention before. This has historical reasons for its development. In the era when the chicken industry began to rise in the last century. They are mainly based on small-scale family breeding, the farming equipment is simple, and the degree of mechanization is low, mainly based on open breeding. Light is also dominated by natural light, and then artificial light is supplemented appropriately. This was mainly due to the consideration of cost savings at the time.
With the development of the aquaculture industry, the breeding scale is constantly expanding, and the breeding level of people is also constantly improving. The drawbacks of natural lighting + artificial lighting are gradually emerging. Open house due to its structure. The small environment in the house will change with the changes in the environment outside the house. Can not provide a stable environment for the flock.
This in turn causes instability in the performance of the flock. such as. On sunny days, the light intensity of the house is too strong, especially near the window VI, causing the chickens to linger, resulting in an increase in the death rate of the flock. On a cloudy day. The light intensity of the house is too dark, especially in the middle of the large-span house. As a result, the feed intake of the flocks decreased and the egg production rate decreased. Compared to an open house, a closed house provides a relatively stable environment for the flock. In turn, the production performance of the flock is fully utilized.
The appearance of a closed chicken coop. Make the house a relatively independent "small environment". It has blocked the intercommunication between the inside and outside of the house as much as possible, and also put forward higher requirements for the environmental indicators in the house. In addition to the precise control of the temperature, humidity and ventilation of the house, it also needs to be equipped with a set. Artificial illumination system with uniform distribution, reasonable illumination and precise control. Currently. The artificial light sources commonly used in the breeding industry mainly include incandescent lamps, energy-saving lamps, and LED lamps.
