1. Brooding methods. Ecological stocking of hybrid chickens is seasonal. The best time for hatching is from March to September. In other months, the weather is cold and it is not appropriate to use this breeding method. Brooding should adopt the online brooding method. Full use of natural light during the day and artificial light at night. The light intensity was 20 lux~25 lux at the early stage (1 day to 4 days of age), day and night illumination; as the age increased, the illumination time and intensity gradually shortened and weakened. Feeding full-price chicks during brooding, the crude protein content is 17% to 19%. Eat freely and drink clean water.
2. Middle-aged chick management. Choose noon at noon to drive the chicks to outdoor grasslands or sloping grounds for feeding on plant seeds and insects. The animal husbandry will be conducted by spreading a small amount of chicken pellets and grains on the grass or on the slopes, and then weaving the feed bowl or whistle to form a conditional reflex so that when it hears the sound, it will come to feed for later implementation. Animal husbandry.
3. Chicken grazing and feeding management. After a period of training, the broiler has developed the habit of grazing and returning to herds and grazing throughout the day. Grazing land should be chosen for arbitrarily arbored woodlands, as shrubs are not convenient for grazing by chickens and patrols by managers. Wild grazing should choose lee, sunny, dry and flat land to build sheds. The shelter can shelter from the rain during the day and can be properly insulated at night. Grazing woodland defines whether the fence is based on the level of management personnel's collection. The fence can use a fishing net of 2 cm 2 cm mesh and a height of 1.5 meters to 2 meters. Stocking densities range from 300 to 500 chickens per 0.067 hectare.
During the grazing period, according to the feeding condition of the chicks, appropriate supplements should be provided, and the clean water basins should be placed in various places in the pasture.
5. During the grazing period, we must collect and replenish every day during the evening, count the number of chickens, and observe the health conditions.
6. Do a good job in disease prevention and control, often disinfect the sheds and utensils, and carry out chicken immunization work according to prescribed procedures.
