The location of the stocking place and the stocking place should be selected in the forests, pastures, desolated beaches, and barren slopes far away from the residential area, industrial and mining enterprises, and traffic trunks. The slope should not be too large, and sandy soil is preferred. It is best to have clean water sources such as streams and ponds in the stocking area for chickens to freely drink water. If not, a certain number of drinking fountains should be placed in the stocking area for every 30 to 50 chickens. The chicken house construction chicken house should be built in the center of the stocking area on the sunny side of Yangyang. The building materials can be adapted to local conditions, local materials, wood, bamboo, plastic, oil felt, canvas, straw, etc. To build a simple chicken house in the north and south direction, with a pyramid or a greenhouse as a good example, with a south door open, the edge of the house is 1
.5 to 2 meters high, and the roof height is 2 to 2.5 meters. The ground is flat, compacted and bedding. The chicken house requires insulation, wind protection, no leakage, no accumulation of water. There are about 20 chickens per square meter in the house. Artificial brooding brooding time is appropriate from March to September. Chicks are bred by artificial methods before the age of 4 weeks, and their diet, drinking water, feeding, ventilation, etc. are the same as conventional brooding. The key to brooding is insulation, which ranges from 33 to 35°C in the first week, and drops to about 2°C per week thereafter. Generally, the temperature is transferred to stocking grounds by the end of the 4th week. Stocking Management (1) The size of stocking should be about 1,500 per group, too large and inconvenient to manage, and too small to benefit. The density of stocking should be controlled within 200 pieces per acre. The stocking density is too high, and the chickens can only collect less food and can not reach the purpose of stocking. (2) Only chickens that have just been transferred to the group need to be stocked. Choose noon on sunny days and rush the chickens to the outside for freeing, let them freely forage, adjust at the same time, and hit the feed bowl or whistle while feeding, so that the chickens form a conditional reflex, and they can quickly concentrate after hearing the signal. For easy management. (3) It is possible to adopt the method of grazing in the early and late evenings after stocking and training. The stocking and feeding should be based on the specific grazing conditions and follow the principle of “early, early, and late, and moderate amount of evening†to increase the growth speed and overall evenness of the chickens. . In addition, in order to reduce the cost of feeding, we should make full use of the leftovers of agricultural and sideline products and prepare their own balanced feeds with balanced nutrition. (4) Observe the flock carefully during grazing, and find sick and frail chickens that are backward, alone, and apathetic, isolate and treat them in time, and pay attention to the invasion of animals such as weasel, eagle, and snake. (5) Pay attention to changes in the weather. Before bad weather arrives, collect chickens in the shed as soon as possible to avoid damage to chickens. (6) In the chicken shed, remove the excrement regularly and do a good job of daily sanitation and disinfection. And according to the local actual conditions, the epidemic vaccination work, pay attention to choose the appropriate vaccine, immunization procedures and immunization methods. General immunization procedures are as follows: 1 day of age, injection of Marek's disease vaccine; 3 days of age, infectious bronchitis vaccine drinking water; 7 days of age, Newcastle disease vaccine drinking water; 14, 21 days of age, infectious bursal disease vaccine drinking water; At the age of 30 days, Newcastle disease vaccine was injected intramuscularly. The slaughter is based on the breed and growth status of the breeder. Between 90 and 120 days of age, the breeder can be sold at one time.
