The characteristics of skin lesions are mainly skin and hair follicle lesions. There are proliferative lesions in the epithelial tissue, prominently over the skin, from white to yellow to form scab, inflammation bleeding, epithelial layer degradation after 2-3 weeks, scab site to stay There are scars, especially in the cocks, fleas, eyelids, and hairless areas under the wings. As body temperature rises, feed intake and egg production rate are affected.
Diphtheria type also known as wet beans in the oral, esophageal or tracheal mucosa surface acute inflammation, and the formation of white opaque fibrinoid cheese-like necrotic aponeurosis, timely removal of the aponeurosis, visible bleeding erosive inflammation, and the chicken survived. If the diaphragm increases, it can clog the throat and cause breathing difficulties and suffocation. The decidua will block the esophagus and affect the feeding.

The diagnosis of chickpea virus infection, acute and chronic, severely affects growth, reduces feed intake, and allows stools to be green and thin and discernible.
Prevention of vaccination is the first choice. In particular, brooding chickens should be vaccinated with chicken embryo-derived attenuated vaccines when maternal antibodies disappear. It is better to strengthen the immunization once a week before starting production.
Vaccine selection Chicken-sourced seedlings are highly toxic and are suitable for large 5-week-old chickens. Chicken-derived virus vaccines are relatively weak, and are suitable for the first immunity of chicks.
Method of use Stabbing method Wings, legs, head with needle or inoculated needle Scratch the skin after the vaccine liquid, 3-4 days, the site of swelling was swollen, after 5-7 days after the pox scarring, when the knot is not Immunity failed and should be re-vaccinated.
There is only one serotype for the treatment of herpes zoster virus. The epidemic prevention and treatment are relatively simple. When a chicken is found to have acne, it is immediately given ribavirin, linolein hydrochloride, and the virus is suppressed. 3 days to control the development of the disease.
