First, brooding management
① Preparation work
Preheat the incubator before hatching to make the temperature of the incubator reach 35 ~ 36℃, and prepare the tray and water dispenser. Put the tray and water dispenser into the fence evenly.
② control of incubation environment
The temperature in the first week is maintained at 33 ~ 35°C, the temperature in the second week is maintained at 29 ~ 32°C, the temperature in the third week is maintained at 25 ~ 28°C, the ambient temperature is maintained at 21~ 24 C, and the age before 10 is 60% ~ 70%, and after/klc. When maintaining the temperature, pay attention to ventilation and eliminate harmful gases in time. The light condition of incubation period is 23 hours a day. In the incubation period, keep the environment quiet and clean the feeders and drinking fountains regularly to reduce the infection of pathogenic microorganisms.
Second, feeding management
① Feeding time
Chickens drink water for the first time 3 hours after breaking their shells, and eat after 24 hours. At the age of 1-3 days, appropriate substances such as glucose, antibiotics, multivitamins and electrolytes can be added to drinking water. Food can be crushed, with comprehensive nutrition, good palatability and easy digestion. In the early stage, wireless feeding was adopted to familiarize chicks with feeding and prevent hunger. After 3 days of age, you can feed it 6 times a day, and then gradually reduce the feeding times. 4-5 weeks old, can be fed 4 times a day.
② stocking time
The stocking time depends on the local climatic conditions and the age of chickens. Generally speaking, it is best to arrive at the beginning of April1end of October. During this period, the woodland was overgrown with weeds and insects, which provided sufficient ecological feed for the chickens. Some farmers lay eggs in summer regardless of the spawning season. Although the temperature is easy to control at this time, the stocking time is short and the feed cost is increased. Hatching in spring is generally better, which can make full use of green feed and forestry agricultural and sideline products and reduce feed cost. When stocking in spring, the outside temperature is above 15℃, which is suitable for stocking.
③ Preparation before stocking.
Stop artificial heat preservation and make the chicken adapt to the external environment. You can try small-scale stocking before stocking, observe the situation of chickens, and then appropriately expand the scope and time of stocking according to the specific situation. Appropriate vitamins and antibiotics can be added to feed before and 3 days after transfer to improve drug resistance.
④ stocking density and scale
Stocking density should be adapted to supporting resources. The principle of stocking is sparse but not dense. The range of chicken raising activities in large chicken farms is generally within the radius of 100 meters, and barbed wire can be used for fences and rotational grazing.
⑤ Feed supply
Although the ecological farm can cultivate Cordyceps in the wild, it cannot meet the production needs and needs to provide more feed. Different feeds should be used according to different growth stages of chickens. The energy and fat content of diet should be increased appropriately in the later period of stocking. Sweet potato and cassava have high starch content and can be used as feed raw materials.
The above is the analysis of the key technical points of brooding and feeding management of black-bone chicken for your understanding, reference and study, and I hope it will be helpful to you.
