Pig pasteurellosis is considered one of the most dangerous diseases that pigs are susceptible to. The main thing is to correctly establish the presence of an infected animal in your pigsty and quickly take steps to treat pigs. It is good to know the details about the vaccine and the prevention of pasteurellosis. About this and talk.
What kind of disease and how does it occur?
This is a toxic form of sepsis or an infectious disease that does not manifest itself regularly. Pig pasteurellosis most commonly affects the lungs. This disease is very dangerous for pigs, but a pig farmer can also become infected. The causative agent is Pasteurella multicida, which can be seen in a blood smear. The optimum temperature for bacterial growth is 36-38 C.
Sources of the disease are infected or ill animals. Their feces and excretions (drooling, snot and feces) contain bacteria. If in the pigsty animals too much and there is a strong humidity, the bacterium develops faster. Other factors contributing to the progress of the disease are hunger and hypovitaminosis.
Infection proceeds in an alimentary and aerogenic way through the skin and mucous membranes. The incubation period lasts from 1 to 14 days. There are two forms of the disease: septic and secondary infection (if combined with other infectious agents).
What are the symptoms?
The septic form proceeds:
- Acute (cough, congestion, mucus with blood leaks from the nose). The animal dies in a week or two.
- Overbuilding (fever, shortness of breath, lack of appetite). Heart activity is disturbed, swelling appears on the neck. Infected pigs die in 24-48 hours.
- Chronically (swollen joints, eczema, weakness, weight loss). Death occurs in 60 days.
Secondary infection may have the same symptoms as the plague. This type of disease occurs as bronchitis, sometimes with the transition to pneumonia. This type of infection can complicate other diseases. Secondary infections are susceptible to weaned piglets.
Disease treatment methods
The most effective drugs are long-acting. Such antibiotics include ecmonovocillin and dibiomycin. To get rid of pigs from the disease using a 5-10% solution of novarsenol on serum. This medicine is given to drink 3 times with an interval between doses - 2-3 days. It is possible to accelerate the treatment if the drug is combined with tetracycline and penicillin. It all depends on how sensitive Pasteurellum (a bacterium of the virus) is to these drugs.
There are also preventive measures. These include strict adherence to the conditions of quarantine when purchasing replacement calves. In addition, care should be taken to vaccinate gilts. In the farm affected by pasteurellosis, it is impossible to take meat to the combine, vaccinate pigs from other diseases. Piglets fed by a sick uterus should also receive their dose of serum.
