Chickens are very sensitive to light and light plays an important role in the growth and production performance of chickens. The general principle of light intensity for chicks is to weaken and increase intermittent light. The effect of light on chicks Reasonable lighting can increase the activity of broilers and improve the health of broiler chicken legs. Decreasing the early growth rate of broilers will help improve the cardiovascular function of broilers, thereby reducing the incidence of ascites and sudden death; reducing feed wastage and increasing feed conversion. Rate; is conducive to energy saving; it is conducive to arrange chickens for drinking water. Daylight management When the chicks enter the brooding room, it means that the brooding is carried out. Three days before the usual brooding, the brooding room maintains 24 hours of light to encourage the chicks to start drinking water. Therefore, ensure that all energy-saving lamps are well lit. The intensity should not be too large, otherwise it will cause paralysis. From the fourth day of brooding, the light time of the brooding was changed to 23 hours of light and 1 hour of darkness. This one-hour darkness is mainly to allow chickens to adapt to power outages without causing riots in the flock. The 23+1 light continued until the 7th day of the brooding. From the 8th day, the light management was changed to 20 hours of light, 4 hours of light was turned off, and the light intensity was halved on the 10th day of brooding. Within 12 hours after immunization, we must ensure that we do not turn off the lights and reduce the risk of stress. After 36 days of age, we must use low light for 24 hours or turn off the lights for 2 hours every day to allow the birds to feed adequately and reduce the feed ratio to promote growth. The broiler brooding period is 4 weeks. In the conventional open broiler house, the brooding light of the first week is the same as that of the broiler broiler, and natural light is used for the next 3 weeks. In the black house, the light is 24 hours in the first 3 days, and the light is 16 hours per day on the 4th to the 7th day. After 3 weeks, the hen has 8 hours of light and the cock is 12 hours.
