Respiratory diseases have a long history in poultry production. The severity of respiratory diseases reflects one aspect of the health and management of a poultry farm. This is not to raise the status of respiratory diseases in the prevention and treatment of diseases, but the occurrence and severity of this disease do have a great relationship with them. At the same time, the evolution of respiratory diseases is also a history of the development of our poultry industry. As early as the 1980s, our poultry industry was still in its infancy and the respiratory diseases encountered were still relatively straightforward. Uncomplicated pathogens were clinically typical, so our veterinarians were easily diagnosed in clinical diagnosis. Although it is difficult to treat, it is difficult to completely eradicate it. However, as long as the right medicine is prescribed and measures are taken in a timely manner, it can effectively control its occurrence and development. With the development of the poultry industry, especially in recent years, respiratory diseases have become complex, out of control, difficult to control, and have a serious prognosis. The main manifestations of chicken disease: The disease is characterized by acute onset, slow transmission, long duration. In the absence of other diseases, only due to changes in temperature, high stocking density, and simple infections during poorly ventilated chicken houses, most chickens have little change in spirit and appetite, and a few chickens have enhanced breath sounds (only heard at night). ). The above-mentioned factors are too strong to cause disease in most chickens. At this time, feed consumption is reduced. In chickens, some chicken eyes can see tears, throwing noses, and facial swelling. Most of the eyes tears are one side of the eyes, but also tears in both eyes. If the treatment does not change to chronic in time, the appetite of the chicken is good or bad, there is caseous exudate in the eye, and some, such as the size of beans, can cause blindness in severe cases. A few chickens died of suffocation due to a blocked throat. If there is no secondary infection, the mortality rate is low. The main pathological change after death of the dead chickens was airsacculitis. The effect of disease on egg production in adult chickens is the least affected in respiratory diseases. However, E.coli is often secondary to the disease in actual production, especially in broilers. As a result, the condition is complicated and the chicken's mortality rate increases. Chickens that died of mixed infection with E. coli showed pericarditis, pericarditis, and airsacculitis after dissection, and some of them also showed pathological changes of yolk peritonitis. In most cases, the disease occurs in the course of many diseases. Therefore, the pathological changes after death of dead chickens can also see the changes of the primary disease. Prevention and treatment of the disease should follow the following principles: As the occurrence of this disease has obvious incentives, prevention work is even more important. In the prevention work, the first thing is to do a good job of vaccination against all kinds of viral diseases; second is to strengthen the management of feeding and management of the chickens, to prevent the heat in the summer to cool down, and to prevent cold and warm in the winter. The ventilation of the house should be done throughout the year to create a better living condition for the chicken. Once this disease occurs, it is important to do its utmost to remove the cause of the disease and improve the environment. This will help reduce the occurrence of the disease and help improve the therapeutic effect. If there are other viral diseases, it is mainly to control viral diseases. In order to prevent the secondary infection of the disease can be properly administered to control. The principle of treatment should take into account the number of affected chickens. When the number of diseased chickens is small, individual treatment is the main method. When the number of affected chickens is large and external triggers cannot be removed immediately, consider combining large groups with individual treatments. The drugs to be treated can be selected as such. Individual chickens can be treated with streptomycin, adult chicken 200,000 units per day, divided into 2 injections, or kanamycin 10,000 units / day, divided into 2 injections, continuous injection of 2-3 days. The whole group can be given streptomycin, erythromycin, renoxacin, Zhiyuanjing, drinking water for 3-4 days. If it is mixed with E. coli, then it is mainly used for treating E. coli disease.

Chicken respiratory disease prevention and control methods
At present, chicken respiratory disease in chicken production is relatively complex, and there are many types of diseases, which are diseases that cannot be ignored. Chickens of all ages can be infected, have a high incidence and are likely to cause secondary infections of various diseases, cause growth retardation of chicks, decline in laying eggs of adult chickens and death of chickens of various ages. Because these respiratory diseases are similar from the clinical symptoms and the performance of the flock, it is difficult to diagnose. For this reason, a differential diagnosis must be made clinically.
