The stocking training of chickens is a key link in feeding, which should be started from the chicks. After being kept in the house for 4 weeks, the chicks weigh about 200 grams. At this time, they are raised in a pasture with a fence, and the conditioned reflex is trained purposefully. After a certain period of training, the chicks come back to eat and drink when they hear artificial voices.

At this time, we should seize the opportunity to train the ability of chickens to forage for feed and forage. After about 4 ~ 6 weeks of training, chicks formed conditioned reflex, and their predation ability and self-protection ability were greatly improved. When a chicken weighs about 500 grams, it has the basic conditions for stocking. You can scatter the chickens in the pre-defined grazing site and start the natural ecological feeding of chickens, so that the chickens can display their abilities in the open Shan Ye, freely catch insects, look for grass and peck at young grass.

The growth period of native chickens is mainly stocking, and they spend most of their time in the wild. Moreover, the growth period in free range chicken is relatively long, which usually takes 4-5 months, and various diseases may be transmitted at any time. Therefore, it is necessary to do a good job in chicken immunization. The prevention of chicken epidemic disease is "important" and "expensive" early, and Marek's vaccine should be vaccinated from the first day after hatching.

At the same time, under the guidance of veterinarians, we should do a good job in vaccination against Newcastle disease, bronchitis, avian influenza, cholera, bursa of fabricius and fowlpox. In addition, we should pay attention to the prevention, control and treatment of other diseases in time to ensure the healthy growth of free range chicken.

Prevention and treatment of chicken virus disease

Newcastle disease is caused by Newcastle disease virus, which mainly manifests as dyspnea, diarrhea, green feces, mental depression and neurological symptoms, head and face swelling, egg laying termination, etc. The mortality rate of sensitive chickens is as high as 50% ~ 70%.

Precautionary measures: Chickens at 7 ~10 days old should be given the first dose of the new bivalent tetravalent vaccine by drinking water or nasal drops, and at 18 days old should be given the second dose, and over 60 days old should be given intramuscular injection of Newcastle disease I (drinking water with Qiwei Kangdu drink before and after each vaccination can effectively improve vaccine immunity and organism disease resistance, and mixing with Hengjiekang at ordinary times can reduce the incidence of Newcastle disease).

Chicken pox is caused by chicken pox virus, scabs can be seen in all parts of the sick chicken, and oral, esophageal and tracheal mucosal ulcers or yellow-white lesions can be seen in laryngeal chicken pox.

Preventive measures:14 ~ 21day-old vaccination with fowlpox vaccine.

Infectious bursal disease is caused by infectious bursal disease virus. The symptoms are white or light green thin feces of sick chicken chops, listlessness, drooping head, closed eyelids, loose feathers, and finally extreme exhaustion and dehydration.

Preventive measures:14 ~ 21day-old attenuated vaccine of bursa of fabricius was used to drink water, and 2% skimmed milk powder was added to the water; Continuous drinking water with Suxiao Bubingning after vaccination can reduce the stress response of the vaccine and control the incidence of bursal disease.
