Porcine Transmissible Gastroenteritis

Update Time:2023/6/29

What is porcine transmissible gastroenteritis?

Porcine transmissible gastroenteritis is an acute infectious disease of pigs, characterized by gastroenteritis in pigs.


What are the symptoms in pigs with porcine transmissible gastroenteritis?

Typical symptoms are vomiting, watery diarrhea with a severe odor, weight loss, and severe dehydration.

Piglets under 2 weeks of age are most susceptible. Morbidity and mortality are high and may result from starvation, dehydration, and acidosis. Within a week of onset, the fatality rate may reach 100%. However, the mortality rate of pigs older than 5 weeks is low.

In adult pigs, the disease is milder, and there may be loss of appetite, weakness, and diarrhea.

Lactating sows may become agalactic.

Transmission route

The incubation period of porcine transmissible gastroenteritis virus is 18 hours. Porcine transmissible gastroenteritis is highly contagious. Once infected, it can quickly spread to the entire pig farm within 2 to 3 days. The infectious period of porcine transmissible gastroenteritis is 40 days.

The mechanism of transmission of the disease is currently unknown and may be transmitted through the following routes: fecal-oral transmission, milk transmission from infected sows, contaminated pig herds, carriage by other animals (such as dogs, cats and foxes), contaminated feed and Contaminated farming material. And the virus can survive stably at low temperature.


1. There is no effective treatment for porcine transmissible gastroenteritis. However, the impact can be reduced in several ways:
2. Infect sows with viruses before delivery, or use isolation for delivery;
3. When introducing breeding pigs, you should only buy breeding pigs from pig farms with negative serological tests.
4. After the onset, respond to symptomatic treatment to relieve hunger, dehydration and acidosis. Treatment involves adding electrolytes to the water to relieve dehydration, and antibiotics or sulfonamides can prevent secondary infections from bacteria.
5. When the disease occurs in pigs, the sick pigs should be isolated immediately, and the pig houses, environment, utensils, and means of transportation should be disinfected with disinfectants. The pigs that have not yet developed the disease should be immediately isolated and raised in a safe place.
