1. Lighting control

Light is an important factor in the growth process of laying hens. As the laying rate of laying hens increases gradually, it is necessary to extend the light time appropriately to ensure sufficient light and promote laying eggs. After research, it is found that if the illumination time is too long or the light intensity is too large, it will easily lead to the phenomenon of licking and rectal prolapse of the laying hens. The lack of illumination time or the light intensity is too weak, which will affect the laying volume of the laying hens.

Generally, during the laying period of the laying hen, at least 8 hours of light should be guaranteed every day. At the beginning of the production period, the light time can be increased to about 10-12 hours. At the peak of laying, the laying hens have greater demand for light, and it is suitable to control the daily light. 16-17h. If there is insufficient natural light, you can use artificial lighting to supplement, turn on the light early, and delay the light-off time. In order to make artificial light similar to natural light, artificial light intensity is controlled at 2-3w per square meter. In the chicken house, the light source should be evenly distributed. Generally, the height of the light source from the ground is controlled to about 2m.

2. Temperature control

The battery feeding technique adopts an important method of efficient whole brooding, which makes the growth space of the chicks more spacious. In the feeding process, only the uniform temperature and the spacious space can provide the basic guarantee for the chicks. Since the temperature requirements of the laying hens are different at different growth stages, the temperature must be adjusted according to different ages when controlling the temperature of the chicken cages. For example, before brooding, the temperature of the house should not be too low or too high. Under normal circumstances, the temperature of the house should be controlled at about 26 °C to achieve warmth. Under normal circumstances, the keeper will adjust the temperature in the house to 26 ° C to maintain the warmth.

In the brooding period, the temperature of the chicken cage can be appropriately mentioned. The high temperature brooding method is adopted, and the temperature in the chicken battery cages is generally controlled at about 33 ° C, and cannot be too high or too low. Due to the low temperature regulation ability of the chicks during brooding, it is necessary to observe the temperature in the house during the feeding process so that the temperature in the house reaches equilibrium for 7 days. If the temperature is high or low, it is easy to cause the chicks to become sick. Resistance and immunity are low. During the breeding period, the temperature in the house should gradually decrease from 33 ° C, and decrease by about 0.5 ° C per week until the egg laying period, and the indoor temperature is appropriately controlled at about 26 ° C.
