Second, reproduction In order to increase fertility, it is necessary to change the natural brood to increase the egg production, generally up to 110-120 pieces/year. Black phoenix chicken breeding years 3-4 years. If the breeding is dominated by machine-incubation, the cockerel is 6-7 months old and the hens can be mated for 10 months. The male-female ratio is 1:6. Incubation should be five levels: Temperature off: 37-38°C is appropriate; Humidity off: 65%-70% in the initial phase of relative humidity, 50%-55% in the middle phase, 65% when the shell is hatched; Turning the egg off: Every 2 hours 1 egg, 18 days after the transfer of the disc to stop turning eggs; egg off: 1 week after the beginning of the egg, 1-2 times a week for 3 weeks, each 3-5 minutes; ventilation off: 1-2 times a day , Incubate for 21 days to hatch and turn to brooding. Third, feeding and management of chicken houses: Choose flat, leeward, dry soil, well-drained place building. Some professional households take the construction of a single type and have a corridor. The north and south sides of the building are located on the north and south sides, and one size window is set on both sides for ventilation and ventilation. The cement floor is favorable for flushing excrement. The south wall has free entrances and exits. Peripheral playgrounds, food and water appliances are distributed on the sports grounds.

Chicks management: mainly "six scratches": 1. Grab the temperature. 1 week of age is 32 °C, after the weekly drop of 2 °C, but not less than 20 °C; 2. Grasp the humidity. Relative humidity 60%-70%; 3. Catch light. 23 hours in 3 to 5 days (including natural lighting), 16 hours later; 4. Grab open food. Chickens eat within 24 hours; 5. Grasp ventilation. Keep the ventilation frequently while maintaining the temperature requirement for brooding; Grab density: 20-30/m2. Broiler chicken breeding: First, male and female chickens should be reared in groups after 60 days of age, and not polyculture. Second, fed compound feeds, with reference to diet formula: 10% wheat, 10% sorghum flour, 10% fishmeal, rice bran Cake 7%, corn residue 20%, bean cake noodles 15%, wheat bran 15%, wheat noodles 6.6%, shell powder 6%, salt 0.4%; third, feeding time, quantitative, set water. Fourth, do a good job of epidemic prevention and epidemics. Regularly observe the dynamics of chickens and treat them as soon as possible.

Clean the hen house on the first side, wash the food and water before feeding, and don't feed moldy feed. Prevent disease: feed 0.02% furazolid in feed for 1-15 days to prevent white spot. The chicks were one-day-old, and 0.2 ml of Marek's disease vaccine was injected subcutaneously daily to prevent Marek’s disease. 7-10 days old with Newcastle disease II. The second is early treatment. Frequently observe the dynamics of the flock and treat it as soon as possible.
