Symptoms and treatment of paratyphoid in piglets

Paratyphoid fever in piglets is an infectious swine disease that can cause the death of a large number of weaned piglets, causing huge economic losses to pig farms. It can occur all year round, especially in rainy and humid seasons. Let’s talk about the symptoms and treatment of paratyphoid fever in piglets.

1. Symptoms of paratyphoid in piglets

1. The initial symptoms of piglet infection are not obvious. The sick pigs gradually become thinner and have a reduced appetite, but they like to drink water.

2. As the disease progresses, the body temperature rises to around 41°C, the patient becomes listless, likes to lie down, has dry feathers, and suffers from periodic diarrhea. Sometimes the feces are mixed with blood and pus, and are foul-smelling.

3. 4-6 days after the onset of the disease or shortly before death, the skin on the ears, neck, lower chest and abdomen of the sick pig turns blue-purple.

2. Epidemic characteristics of piglet paratyphoid

1. This disease mainly infects piglets and is often seen in rainy seasons. It is mostly sporadic or endemic and spreads slowly.

2. Pig farms with poor feeding management and sanitary conditions are prone to this disease.

3. Piglets infected with paratyphoid fever will become extremely emaciated and suffer from persistent or periodic diarrhea.

3. Prevention of paratyphoid in piglets

1. There are many reasons for the occurrence of piglet paratyphoid. Poor feeding management and sanitary conditions are the main factors that cause piglets to be infected with piglet paratyphoid and spread the infection. Therefore, it is necessary to improve feeding management and sanitary conditions, enhance the disease resistance of piglets, keep the pigpen clean and dry, and raise piglets in groups according to their size and physical strength.

2. Give piglets a preventive injection of attenuated paratyphoid vaccine.

3. When paratyphoid fever occurs in piglets on site, the sick piglets should be isolated and treated in time, and the pigpen should be cleaned immediately and thoroughly disinfected. Commonly used disinfectants include 2-4% sodium hydroxide solution and 10-20% lime milk .

4. Dead pigs must be buried deeply or burned, and healthy pigs must be immediately given preventive vaccinations. If there is no vaccine, you can give the piglets furacillin orally, 0.1-0.5 grams per day, and take it continuously for about half a month to see if it will be effective.

4. Treatment of paratyphoid in piglets

Chloramphenicol 10-30 mg per kilogram of body weight is injected intramuscularly 1-2 times a day, or oxytetracycline 10-30 mg per kilogram of body weight is injected intramuscularly 1-2 times a day, or chlortetracycline 10-30 mg per kilogram of body weight is injected intramuscularly 1-2 times a day. Alternatively, take 0.4-0.6 grams of sulfaguanidine per kilogram of body weight, divided into 2-4 doses, or take 10 mg of furacillin per kilogram of body weight, divided into 2 doses, for 5 consecutive days.

That’s it
