The Breeder Management Technique of Black Phoenix Chicken


Chinese black phoenix chicken, black silky black bone chicken, also known as Wufeng chicken. The chicken is one of the most promising breeds in China's special poultry breeding industry. Black chicken has a high nutritional and medicinal value. In the current domestic and foreign market competition, it has great potential for development. Now, the main points of feeding and management techniques for the black phoenix chickens are described below.
Based on the biology and growth characteristics of the black phoenix chicken, 0 to 6 weeks old chicks can be used as a feeding and management stage.
1 Preparation before brooding
1.1 Preparation of brooding sheds The brooding sheds should be thoroughly cleaned, then thoroughly sterilized with 2-3% flaming alkali, and then bred on the four sides of the larvae with lime gouache; the amount of drinking fountains and feeding troughs should be sufficient, first use 1% fire. The alkaline solution was disinfected, and then washed and dried with water. The ground litter in the brooding house was required to be clean and clean. The brooding house was pre-heated for 2 days before hatching, and the temperature was kept at about 32°C after entering the chicken.
1.2 Preparation of feed and medicines Preparation of chicken ND, bursa, infectious bronchitis, egg drop syndrome, Marek’s disease vaccines, and other medicines to prevent chicken fleas, coccidia and E. coli, etc. before brooding During the brooding period, do a good job of preventing rats, dogs and cats. The broiler house requires strict doors and windows, good heat preservation, dryness, hygiene, and moderate lightness, which is conducive to ventilation.
2 Selection and delivery of chicks Young chicks should be free of deformities, lively and lively, with great eyes and eyes, sounding loud, good villi covering, shiny, moderate in size on the abdomen, sensitive to reaction, standing firm, no traces of blood and inflammation in umbilical cord, cloacal cavity clean , No yellow and white fecal adhesions, full hand grip, struggling, etc.; black phoenix chicken is also a 21d hatching, after the feathers can be dry packed and transported, but the transport of cardboard boxes should not be too large, generally 50 ~ 60cm, width 30 ~ 40cm, install 80 ~ 100 chicks, a small number of holes in the box wall, in order to facilitate ventilation, transportation should pay attention to insulation, on the way to diligently check to prevent overheating, bored, frozen, squeezed, under pressure.
3 Brooding methods Black phoenix brooding brooding methods include cage breeding, online brooding, ground level raising, and fire brooding.
3.1 Temperature Black phoenix chicken is smaller than ordinary chickens, feathers are thin, but also feathery feathers, heat dissipation is fast, so the temperature required for brooding is higher than that of laying hens. The approximate requirements for the temperature are: 35 to 33°C in the first week, 32 to 31°C in the second week, and 2°C in the subsequent week until it is maintained at 24 to 23°C after 6 weeks of age, but what kind of temperature is actually supplied? Appropriate, depending on the state of the chicken, when the temperature is appropriate, the chicks are lively and active, appetite is strong, sleep is quiet, the sleeping position is stretched comfortably, the flock is evacuated and evenly prone.
3.2 Humidity
The relative humidity in a room of 1 week old is 65-70%, and the relative humidity in the room from the second week of age should be 55-60%.
3.3 Breeding density Suitable density for brooding period (only/square meter): 50 birds per square meter for 1 to 2 weeks old; 30 birds per square meter for 3 to 5 weeks old; 20 birds per square meter for 6 to 8 weeks old .
3.4 Ventilation General requirements The concentration of ammonia in the house is less than 20mg/L, the hydrogen sulfide is less than 10mg/L, and the carbon dioxide content is below 0.5%. In the north, attention should be paid to solve the conflict between ventilation and temperature, and special attention must be paid to not allowing The air enters directly, and the ventilation standard is such that people do not feel boring and pungent and hot eyes in the house.
3.5 Light The broilers hatched to 3 days of age, generally using 24 hours of light, 18 hours of light after 3 days of age, and then half an hour later, gradually approaching natural light.
3.6 drinking chickens into the house, rest 1 ~ 2h should first drink water, and then feed, chicks do not drink cold water within 1 to 2 weeks, you can put cold water in the chicken house before the pre-temperature drink, drinking water must be timely, Do not cut off water and change the water if it is found that the water is contaminated by faeces.
3.7 Feeding When the chicks drink water, they find that one-third of the chickens can eat when they seek food. After the first 3 to 5 days after the start of eating, they can mix the whole dry powder with water (reach the hand into a group, landing is scattered ) Sprinkle on the tray or non-toxic plastic cloth, can be transitioned to dry powder feed after skilled in feeding, 2 to 4 weeks old feed into the feed tank, feed to feed less feed Tim feed, feed 80% The principle of satiety, feeding 6 to 7 times a day in the first week, 5 to 6 times a week later, with the shortened light time, gradually reducing the number of feeding.
4 Do a good job of observing the flock. Observing the flock is an important task in a day's work. Observe that the flock dynamics can be known at any time so that appropriate measures can be taken to ensure the normal growth and development of the flock.
5 to develop a scientific immunization program for disease prevention chicks 2 weeks of age attention in the drinking water or feed to prevent chicken psoriasis drug; after 2 weeks of age at any time pay attention to the occurrence of chicken coccidiosis, and do preventive work. In addition to this, immunization must be done. The immunization procedure is as follows: Marek's disease vaccine injection is given 24 hours after hatching, subcutaneous injection of 0.2 mL; 3 to 5 days old, 1st bursal vaccine dose or 2 times Drinking water, drinking water, it is best to add 0.1% skim milk powder to the water; 7 to 8 days of the first infectious bronchitis vaccine eye drops eye immunity or 2 times the amount of drinking water; 10 to 15 days old, the first Newcastle disease drops Nasal, eye immunity or 3 times the amount of drinking water; 18 to 20 days of age, the second immunization of the bursa of Fabricius; 20 to 25 days of age, the second immunization of infectious bronchitis; 35 to 40 days of age, contagious Laryngitis immunization; 3rd immunization of Newcastle disease virus IV from 50 to 55 days; Newcastle disease vaccine immunization at 70 to 75 days of age; Immunization of infectious laryngitis from 80 to 90 days; Integrated egg reduction from 120 to 140 days Immunization; immunization with Newcastle disease virus I was performed every 3-4 months after 150 days of age.
