Black phoenix chicken, also known as black feather chicken, is a unique and rare source in China. Breeding management Chinese black phoenix chickens were bred from the brooding to the rearing stage of chicks (7-25 weeks old). This period should reduce the energy and protein levels in the diet, increase the amount of bran and green feed, and reduce the amount of concentrate. The number of feeding troughs is required to ensure that each chicken eats well and is weighed regularly. Commercial chickens can be listed on the 100th day of age. Reserve chickens from 100 to 180 days old are reserved for breeding chickens. Select chickens to work in groups, grouping them according to their size, strength, and male and female. Each group is suitable for 250~300. (1) De-warm: Black chicken is about 6 weeks old. All the hairs are replaced with silk hairs. The silk wool insulation performance is poor. Generally about 9 weeks old, the black chicken's thermoregulation capacity is improved. At this time, the de-warming takes place gradually and begins at daytime. Warming up, still need to warm up in the evening. (2) Preparing for entering a breeding home: Before the person is educated, he should disinfect the breeding house, feeding trough, and drinking fountain, prepare feed, litter, and medicine, and organize the manpower to do a good job of selecting chickens. (3) Exercise and Density: The growth period is an important period for long bones and muscles. Therefore, sufficient activity space should be provided to strengthen the movement of the chicken and obtain a strong constitution. Under flat-knit conditions, the rearing densities of 9-13, 14-17, 18-25 weeks/m2 were 15, 10, and 7, respectively. (4) Strict control of light: The light duration in the rearing period is usually 8 to 10 hours. (5) Limiting rearing and regular weighing: The weight of black phoenix chicken has a direct impact on the future egg production. In this period, the energy and protein levels in the diet should be reduced, and the amount of bran and green feed should be properly increased to reduce the amount of concentrate. . In the feeding restriction process, the number of feed troughs is required to be sufficient, and the speed of the sprinkling is fast to ensure that each chicken eats well. At the same time, weighing is performed regularly to require 750 g at 90 days, 900 g at 120 days, and 1100 at 150 days. Grams, 1,180 grams per day, 180 days, 10% every 2 weeks, if the average weight is lower than the standard value, you should increase the amount of feeding or feeding, and vice versa, reduce the number of feeding. Feeding management of adult chicken (1)Environmental hygiene: Before the production of black phoenix chickens, the broiler houses should be thoroughly cleaned and disinfected. (2) Transfer to group: The transit time is generally 22 to 24 weeks old, and the vaccination is completed once before the group is transferred. When selecting a group, select only suitable weight and healthy chickens, and gently handle them to avoid mechanical injuries and unnecessary deaths. Increase the proportion of vitamins in the diet and add a certain amount of antibiotics to the group. To improve anti-stress ability. (3) Temperature: The temperature in the house is best controlled at 16~21°C. If the temperature is too high or too low, the egg production performance will be degraded and the cost will increase. If the temperature is too high, it is easy to cause brooding. (4) Light is suitable: Light is closely related to egg production. Generally, the light intensity of a 40-watt bulb with an area of ​​15-20 square meters is sufficient. Black Phoenix chicken egg production peak requires 16 hours of light daily. The lack of natural light is supplemented by artificial lighting.
