1. Introduction
Transmissible gastroenteritis (TGE) is an infectious disease caused by coronavirus. The disease is characterized by vomiting, severe diarrhea and, high mortality rates (typically 100% in piglets under two weeks of age ).
2. Etiology
TGE is caused by coronavirus genus resulting in gastritis and enteritis with high mortality in newborn piglets from 1-10 days of age. This decreases in pigs at five weeks of age or older
The disease spreads primarily by direct contact; the main route is oral. TGE can be transmitted through food, water or by workers (limbs, shoes) or dogs and cats, mice, birds carrying the disease from one place to another.
3. Symptoms
- The incubation period is short from 18 - 3 days, the disease spreads rapidly in the herd, just after 2-3 days, most of the pigs in the herd are infected. The disease commonly occurs in winter.
Typical symptoms: Typical signs include vomiting, watery diarrhea in yellow color, rapid weight loss, dehydration, very high morbidity and mortality rate in piglets at the age of two weeks Diarrhea is a common sign. Feces often contains undigested milk.
- Most of the pigs under seven days of age often die after 2-7 days. Pigs at three weeks of age may survive but often exhibit rickets
Clinical signs observed in meat pigs and fattening pigs are diarrhea often not apparent within a few days, sometimes vomiting, in some cases death due to secondary infection or stress.
If sows are not in contact with infected pigs, they often have subclinical signs or nonspecific symptoms such as high fever, loss of milk, anorexia, diarrhea.
- When the disease is concurrent with certain viral or bacterial infections of the respiratory tract such as PRRS, mycoplasmosis in pigs the disease will be more severe.

4. Lesions
Lesions are often restricted in the gastrointestinal tract except for cases of dehydration
The lesions may include distended intestine containing a lot of fluid and yellow foam, clumps of undigested milk, thin and transparent intestinal wall due to atrophy of villi often occurring in jejunum and ileum.
No lesions are present in the lungs of naturally infected pigs.
- If the disease is concurrent with respiratory diseases, lung lesions may be present.
5. Prevention
- VAC PED vaccine is given
- Periodical hygiene, disinfecting animal houses to kill pathogens in the farming environment should be performed.
Resistance to diseases for animals: tonic vitamin supplement, providing sufficient feed and drinking water for pigs should be carried out
- The spread of the disease must be prevented
- Sows are vaccinated to protect baby pigs.
- Marflomix antibiotics or Tyvalmix is periodically mixed with feed at the preventive dose to prevent the common diseases in pigs, at the same time improving the resistance of pigs by dissolving some preparations belows: Marphasol Herbal or Electrolyte glucose K - C in drinking water continuously or periodically.
6. Treatment
* Regimen 1: Cefquinome in conjunction with Para 150 20% is injected
* Regimen 2: Cefa 20% - La along with Herbal Marphasol
