Temperature and light requirements of chicken house for layer breeding equipment

One of the main factors affecting the utilization rate of feed for chickens in layer chicken battery cage system is the environmental temperature where the chickens are located. In a low-temperature environment, chickens consume more food because they use part of their energy to maintain normal body temperature. In a high temperature environment, the feed intake of chickens will decrease, and the feed utilization rate will be relatively poor, because the biological cooling mechanism of chickens in hot conditions also requires energy. By providing the best environmental temperature, the chicken can use the various nutrients it has absorbed for growth and reduce it to regulate body temperature.






The temperature requirement of the chicks house: The house temperature requirement on the first day of brooding is slightly higher, reaching 33-35℃, and then dropping by 2-3℃ every week until it can stabilize within the range of 16-21 ℃.


Growing house temperature requirements: The most suitable house temperature for growing chicken house is 13-23℃, the lowest is 5℃, and the highest is 30℃.


Chickens are long-day animals. The chickens must have reasonable light in various feeding periods. Under suitable light conditions, the performance of chickens can be improved. When designing the lighting, the illuminance of caged chickens should be increased, generally at 3.3 to 3.5 watts/square meter. Usually when the lamp is 2 meters high, the lamp distance is 3 meters, 2.7 watts/square meter or 1 watt/0.371 square meters, the illuminance equivalent to 10 Lx can be obtained.


From the 3-7 days after the chicks emerge from the shell, the daily light is 23.5-24 hours, and then gradually shortened to 8-9 hours, until the age of 18-20 weeks. From then on, add 0.5 to 1.0 hours per week until it reaches 14 to 16 hours of light, and thereafter remain unchanged. Under normal circumstances, the brooding period (0-6 weeks of age) chickens require 23 to 18.5 hours of light, the light intensity is 10 to 30 Lx, and warm color light sources are the main ones; the light time requirement of the rearing period is 8 to 9 hours, The light intensity is 5 Lx, warm color light source; the light time requirement during the laying period is 14-16 hours, the light intensity is 10-12 Lx, and the cold color light source is the main.
