How to prevent and treat Japanese encephalitis in pigs? How to prevent encephalitis in piglets

Porcine encephalitis is a common disease in pig farms, and the threat is ranked among all swine diseases. Some new farmers are helpless against swine encephalitis, and they suffer heavy losses as soon as they get sick. What is the reason for the occurrence of such a destructive swine disease? Is there any quick** way?

Types of porcine encephalitis.

1) Acute porcine encephalitis: This type is very difficult, sick pigs go crazy, scream, protrude blood vessels in the ears, and generally die within an hour. For this type of disease, we can try to treat sulfonamides, but the effect is generally not very ideal.

2) Subacute swine encephalitis: The symptoms of this type of swine encephalitis are relatively mild, and pigs generally lie on the ground every few minutes and twitch and foam at the mouth.

3) Chronic swine encephalitis: such symptoms are the mildest, about five times a day, the duration is short, basically the sick pig falls to the ground and convulses, neighing, coughing, and diarrhea.

Causes of porcine encephalitis.

In most cases, pig encephalitis is caused by our improper feeding management, such as unbalanced feed nutrition, excessive density of pigs, poor ventilation of the enclosure, accumulation of manure, and lack of regular disinfection of the enclosure (the most serious in summer, because bacteria breed, too many mosquitoes and flies are easy to spread encephalitis virus).

In a small number of cases, porcine encephalitis is caused by the lack of prevention by our vaccines, which can lead to poor vaccine quality, non-standard vaccination measures or high PRRSV levels in pigs. Diseases that cause porcine encephalitis include streptococcus, Japanese encephalitis, Listeri, pseudorabies, salt poisoning, heat stroke, heat stress, etc.

How ** swine encephalitis.

There is no specific drug for this disease, if the symptoms of the sick pig are mild, interferon and sulfonamides can be used**. If swine encephalitis is caused by pathogens, quinolones, sulfonamides, and doxycycline can be used**. If the pigs can be fed normally, only oxytetracycline mixture will do.

For swine encephalitis caused by salt poisoning, a large amount of fresh water should be administered first, and then intravenous glucose normal salt is solution, mannitol, sulfadiazine sodium**. The most important point is that porcine encephalitis is generally a secondary symptom of other diseases, and we must first determine the real disease and figure out the original disease in order to improve the probability.

Porcine encephalitis is often caused by streptococcal infection, to prevent swine encephalitis, it is necessary to pay attention to regular disinfection and sterilization of pig sheds, and at the same time to regularly add corresponding antibiotics to pig food on weekdays.

Encephalitis in pigs is caused by unscientific feeding processes, such as unclean pigsty, unbalanced nutrition of the feed and poor observation of the health of pigs. The way to prevent it is to raise pigs scientifically and pay attention to the health and safety of the pigsty.

Porcine encephalitis is caused by improper feeding management and inadequate vaccine prevention. Usually do a good job of sanitation for pigs, frequent disinfection and sterilization, ventilation, and keep the pig house dry. At the same time, the time for injecting pigs with vaccines should be reasonable, and regular vaccines should be used.

Encephalitis is generally sudden, and most of the pigs get encephalitis because they have not been vaccinated, and the health work has not been done well.

Body temperature: degree, pig, lying on the ground on his side, very poor spirit, shallow and fast breathing, soft rear drive, can no longer stand up, touching, the pig has a scream, the conjunctiva of the eye is flushed, the eyelid is slightly swollen. Mucous nasal discharge in the nostrils, dry nasal mirror.

The stool that is passed is also normal... Nothing else is out of the ordinary.

What is the most effective** method of encephalitis? Porcine encephalitis can present with general encephalitis symptoms or focal symptoms, accompanied by severe cerebral dysfunction. Let's take a look at the symptoms and methods of porcine encephalitis.

1. The main symptoms of porcine encephalitis.

The main symptoms of porcine encephalitis.

The main symptoms of porcine encephalitis are: limb disorders, blind circles, empty chewing, teeth grinding, screaming, staring backwards, convulsions, muscle tremors, ears erect, head back and other neurological symptoms, hindquarters paralysis and then fall to the ground, limbs do paddling; The body temperature rises to 40 42, appetite is lost, the stool is volley-shaped, and there is a serous nasal juice discharge from the nostrils; When dying, the temperature drops, and he falls asleep until he dies. Some diseased pigs have different degrees of swelling in their joints.

2. The most effective method of porcine encephalitis.

Porcine encephalitis is a more effective method.

1) There is no effective method for viral diseases, and interferon, ribavirin, antibiotics and symptomatic symptoms can be tried for mild symptoms.

2) Caused by bacterial diseases, inject with sulfadiazine sodium, quinolones, ampicillin, doxycycline, etc. For pigs that can be fed, they can be fed with quinolones or doxycycline and oxytetracycline mixtures.

3) Caused by salt poisoning, a large amount of fresh water or sugar water should be administered, and intravenous glucose saline, mannitol, and sodium sulfadiazine should be injected.

4) The clinical symptoms caused by lead poisoning are rare, and pigs have greater resistance to lead poisoning. Lead poisoning can be caused by lead mines, water or feed contaminated by lead smelters, motor oil containing lead, and feed contaminated with paint. **1-2 grams of calcium disodium monoenediaminetetraacetic acid dissolved in 5% glucose saline 100-500 ml intravenously twice a day for 3-5 days can be used.

3. Preventive measures for porcine encephalitis.

Preventive measures for porcine encephalitis.

1) If it is caused by infectious factors, it is necessary to do a good job of hygiene and epidemic prevention and get vaccinated in a timely manner.

2) Strengthen feeding management, strictly control the amount of salt in the feed, and do not use or use less leftovers and swill in restaurants and canteens to feed pigs; Prevent harmful substances from polluting feed and drinking water.

4. Common causes of diagnosis and treatment errors of porcine encephalitis.

Porcine encephalitis**.

Pig encephalitis and meningitis are mostly caused by other diseases, and the clinical manifestations are very similar to the neurological symptoms.

Japanese encephalitis occurs mainly in the summer, and piglets born to infected sows are more common; Porcine pseudorabies is mainly caused by newborn piglets to weaned pigs; Listeria occurs mainly in weaned piglets; Streptococcus suis is mainly found in summer shelf pigs; Heat stroke occurs in the hot season, when the feeding environment conditions are poor, and the weather is hot and humid without ventilation or direct sunlight; Salt poisoning is caused by too much salt in the feed.

The more common encephalitis in piglets is caused by streptococcus.

The prevention of bacterial diseases is: pay attention to hygiene, frequent disinfection and sterilization, ventilation, and keep the pig house dry.

Emergency** medication (optional): 1Analgin + penicillin + dexamethasone. 2.Sulfahexamethyl (good effect).

Intramuscular injection, and sulfahxamethyl** continued for two days after symptom relief.

If other diseases caused by streptococci occur frequently, such as arthritis, purulent lymphadenitis, or acute sepsis, streptococcal vaccination is recommended.
