What are the symptoms and prevention measures for chickens? – Boultry prevention and control – China Animal Husbandry Website – A useful animal husbandry website
The airbag is generally caused by pathogens such as viruses, mycoplasma, E. coli. Since the symptoms are more, they can continue to be completely cured. At present, there is a lot of popular markets, bringing great losses to the farming industry.
Pathogen is complex: Most cases of airbag is not a separate disease, but a symptom of systemic infection.
Due to disinfection Reduced secretion, leading to a disease in the pulmonary disease, the airbag has a sharp drop in the purification rate of E. coli, and the occurrence of airbagitis is inevitable. 3. Special: 9 airbags in the chicken. The structural characteristics of “upper respiratory-lung-airbag-bone” are connected to each other, making the broiler body a semi-open system. The pathogenic microorganism in the air is easy to enter the bone to form a systemic infection through the upper respiratory tract, lung, and the airbag. In addition, since the chickens do not have the diaphragm, chest, intraperitoneal, and it is easy to cause airbag infections after the disease occurs. These features are the main causes of multiple brain bladder. Disease chicken respiratory symptoms, tensile neck breathing, asthma, nose, snoring, swelling, swollen eyes, tears, individual chicken swelling swelling The spirit is euphemistic, loss of appetite, even abolished, thirsty, pull yellow white, dry, no shiny, crown claws dry light. Dirty chicken is violent, the oral cavity is filled with mucus, severe cases, cut the belly skin can see fat yellow or inflammatory oozing. Open the abdominal cavity, the chest airbag is filled with yellow cheese samples, heart-packaged liquid, vesicle pouch, yellow serial, 30% of the disease dead chicken with heartbend inflammation, hepatic disease, splenome, small intestine, small intestine The nasal cavity is filled with mucus. The main cause of the disease is very large, the environmental factors are very large, and the feeding of the chicken farm, once the disease is very good, the mortality is very low, Once the chicken farm with poor feeding, once it is absent, it is not good to control, and it is getting more and more heavy, the mortality is high. So the environment is controlled to thisThe development of disease is very important. Especially in winter, it is recommended to breed friends to bind the wind turbine, the fan part uses the plastic cloth, prevent chicken, because the chicken is long, use ventilation tubes, it is recommended to use the hand to feel the other-air tube of the fan with the hand, if there is a wind, consider Suitable, if it is not recommended to block the ventilation tube of the fan, the front head is large, and there is no pressure in the back. Strengthening feeding management, avoiding stress, such as immunization, replacement, and stroning groups. Controlling environmental factors is to prevent the most direct measures in various respiratory diseases, thereby avoiding airbagitis. Support enough nutrients to the chicken group, do a good job of daily disinfection and hygiene, keep the chicken farm, and the environmental hygiene of the chicken house. For sick and dead chickens, they will prevent infection sources, and give a good living environment. The chicken farm should establish a biosafety system and use a full-time production system.
