Strengthening lighting management should not only pay attention to the effect of light time, but also can not ignore the effect of light intensity. The response of chickens to light stimulation depends on whether the body weight is up or down, whether the flock uniformity is good or not, and whether the nutritional intake is sufficient. Therefore, according to the above 3 points should be timely light stimulation, and pay attention to uniform light. At the same time, the intensity of the light stimulus should be at least 10 times that before the stimulus, and the effect is better. Establish a good microclimate environment in the henhouse to maintain a reasonable breeding density; equipped with adequate feeding equipment; feed quickly and evenly; maintain good ventilation; strengthen litter management; supply high-quality full-priced feed; careful management, reduce stress, for Chickens create a good environment. In accordance with the law of growth, body weight at 4 weeks of age should reach the standard or slightly exceed the standard, and chickens below the standard weight should not be allowed; so that the breeder has better skeleton development, because more than 85% of the skeleton development of the breeder at 8 weeks of age has been Basic completion; through the control of the amount of material before 10 weeks of age, as many as possible breeder weights meet the standards recommended in the Feed Management Manual; after 10 weeks of age, especially after 15 weeks of age, the weekly weight gain should reach the standard; after 10 weeks of age the weight exceeds the standard The flock should redraw the weight curve, can't force back to the standard curve, but should increase along the standard curve in parallel. Weighed at least once a week before 40 weeks of age; once every 2 weeks after 40 weeks of age, in order to timely grasp the growth and development trend of breeders, timely adjustment. Maintaining a good uniformity of the breeder breeder maintains a good uniformity of the breeder, and its production value and economical efficiency will be higher. Therefore, the uniformity of the breeder should be grasped from the age of 1 day. The better the uniformity, the higher the production performance of the flock. Before 10 weeks of age, we should focus on the regulation of uniformity. The goal of uniformity control must reach 85% or even higher.
