Prevention and control of laryngitis after immunization

The symptoms of laryngitis are obvious, with severe respiratory symptoms, typical symptoms of chickens stretching their necks to breathe, rales, and hemoptysis. The laryngitis vaccine should be vaccinated urgently after diagnosis to avoid mass casualties. Chicken farms near the diseased chicken farm should also be vaccinated against laryngitis vaccine, because the laryngitis vaccine is a moderately virulent vaccine, and some serious vaccine reactions will occur after immunization. Therefore, after laryngitis vaccination or normal vaccination Do a good job in prevention to prevent the outbreak of other diseases.

Nowadays, laryngitis vaccine immunization is mostly based on eye spotting, regardless of domestic vaccine or imported vaccine, immune stress is great. The main manifestations are: the chicken is depressed, the feed intake is reduced, the eyes are tearful, and the eyes cannot be opened due to severe sealing of the eyes. In some chicken farms close to each other, atypical laryngitis occurred in other chicken farms due to the immune laryngitis vaccine.

The disinfectant in the chicken house should be less irritating and not harmful to the mucous membrane. Environmental disinfection can be caustic soda or peracetic acid.
