It's getting cold, chicken breeder, you should do this


Autumn has been a long time, the weather turned cool, the most painful respiratory disease Mycoplasma gallisepticum infection is more and more. Mycoplasma gallisepticum infection, also known as "chronic respiratory disease", is also known as "stress disease". No matter how well management measures are taken, once the chickens are stressed and weather changes, respiratory diseases will definitely rise. At present, many chicken breeders do not know enough about mycoplasma infection, and use drugs when they have respiratory symptoms, which leads to the failure of symptomatic treatment, resulting in different degrees of loss.The following is a brief introduction of Mycoplasma gallisepticum infection and control measures:

ⅠClinical symptoms

1.Mycoplasma infection of chicken has a long course of disease, which can be as long as 1 month. The young chicken is characterized by sneezing, runny nose, cough,  rale, rhinitis, sinusitis, exudate in nasal cavity and inferior orbital sinus, swelling of eyelids and eye protruding, which eventually leads to blindness. Adult chicken performance is similar to that of young chicken, but the symptoms are mild, and the egg production rate and hatching rate of seed eggs are reduced.     

2.When Mycoplasma gallisepticum is mixed with E.coli, infectious bronchitis, Newcastle disease and infectious rhinitis, nasal juice increases and blocks nostrils, which is prone to aerocyst, perihepatic inflammation, pericarditis and peritonitis, and the mortality rate is increased.    

3.Mycoplasma infection is easily induced when inoculated with freeze-dried vaccine such as Newcastle disease, infectious Laryngotrachitis and Bursa of Fabricius. The clinical manifestations are: cough and sneeze for a long time appear in the chicken group 2-3 days after immunization.

Ⅱ Symptoms of autopsy

The main lesions are respiratory tract, mucus in the trachea, inflammation of nasal mucosa, flushing, and sometimes there are foam like or caseous substances in the airbags. If secondary E. coli is found, it will show Perihepatic inflammation and pericarditis. If secondary atypical Newcastle disease occurs, it will show a slight swelling of the gland stomach papilla, intestinal lymph follicle swelling and bleeding.


Ⅲ Prevention and control measures

1. Strengthen the feeding management, reduce the feeding density and improve the sanitary conditions. V Lai-immune enhancer and compound vitamins can be added for a long time to improve the disease resistance and avoid various stress reactions.

2. Zhibituo No.1 and Zhibituo No.2 can be used-For Mycoplasma gallisepticum and E. coli immune microecological agents, do a good job in prevention and health care.

3. Strengthen ventilation, adhere to disinfection with chickens, and use Taiji Decoction No. 2 - Environmental improver to improve the air quality of chicken houses, which is conducive to accelerating the recovery of sick chickens. Remember to raise the temperature of the house by 1 ~ 2 before ventilation to prevent cold.
