During the spring and summer communication period, due to rapid temperature changes and large winds, many chicken flocks have occurred, especially in the recent bronchial blockage of broilers, lung necrosis and blood stasis, which have caused significant losses to farmers.

Causes

1, The root cause of this disease: chickens viral diseases hidden infections.

2, The chicken house is high temperature and low humidity, the air is dry, causing respiratory mucosal damage.

3, The chicken house high temperature and high humidity, ventilation is too large, the wind speed is too large, the body temperature drops rapidly, the chickens are cold.

4, The temperature difference between the day and night is too large, the climate is not normal, the weather is abrupt.

5, The long-term negative pressure in the chicken house is high, causing partial hypoxia in the chicken house.

6, Chicken lung dysfunction, lung necrosis, pulmonary edema, bronchial blockage.

Case study

In Rizhao, the farmer raised 40,000 broilers, each of which had 20,000, and began to develop from a chicken house for 20 days. The death rate rose to more than 400 and spread to the audience.

Clinical symptoms

Large group of obvious cough, dry cough is very powerful, strange hook hook, feathers are reversed, hair color is dark, feed intake is reduced by 1/2, and the first half of the house is obviously serious.

Anatomical symptoms

Tracheal mucosal hemorrhage, black lungs, blood stasis, squeezing foamy liquid, bronchial embolism, non-blocking chicken mainly showed lung blackening, edema, chest airbag with yellow-white cheese, poor abdominal balloon symptoms, the main cause is in the lungs and On the trachea.

Diagnosis

Lung necrosis caused by colds in the flock, bronchial obstruction

Medication plan

Clearing away heat and detoxifying, cooling blood and eliminating spots, refreshing and adding materials: Qingqi Jiedu oral liquid 1000 kg of water, used for 4 days.

After 2 days of treatment, the number of dead chickens decreased by 1/2, the incidence of chicks gradually decreased, the feed intake increased by 30%, and the large group of respiratory tracts were significantly reduced!

Summary

Every spring and summer communication period is the most difficult season for broiler chickens. It is necessary to strengthen prevention and control in management ventilation. Beware of chickens suffocating and cold, and early adjustment of heart and lung function can reduce the occurrence of diseases.
