May. 17, 2018

Chicken infectious rhinitis occurs frequently in the cold season, and generally occurs in late autumn and winter. It has the characteristics of aggressiveness, rapid transmission, high incidence, and low mortality. The incubation period is short, usually 1 to 3 days. The most obvious symptoms of diseased chickens are facial swelling, serous, mucinous secretions in the nasal cavity and paranasal sinuses, inflammation of the conjunctiva, swelling of the tissues around the side of the eyelids, severe blindness, marked edema of the meat carcasses, and inflammation of the upper respiratory tract spreading to the trachea and difficulties and murmurs appear in the lungs. Adult diseased chickens are anorectic at first, close their eyes to sleep, and do not want to walk around. They have a serosal nasal fluid. Later, one or both bilateral edemas appear in the eyelids and the face, and there are purulent discharges in the nasal cavity. Breeding chickens mainly exhibit delayed production, and the growth and development of chicks are hindered. The egg production of egg-laying chickens decreased significantly, and the egg production decreased more significantly at the peak of egg production. Tylosin Tartrate is an effective drug for chicken infectious rhinitis.
