Porcine transmissible gastroenteritis is caused by porcine transmissible gastroenteritis virus, and pigs of all ages are susceptible to it. Once the new pig farm gets sick, it spreads quickly and spreads all over the construction site. The mortality rate of infected pigs within 2 weeks old is very high, reaching 100%, and the breeding pigs and adult pigs often take a benign course. It mostly happens in winter and is not popular in hot springs. Sick piglets often vomit after breastfeeding and soon have severe diarrhea. The feces are watery, yellow or grayish white, with undigested small curd lumps and foul smell. Sick pigs quickly dehydrate and lose weight. The mortality rate decreases with age. The younger the age, the shorter the course of disease and the higher the mortality rate. Affect the growth and development of rehabilitation pigs. There is no effective treatment.
Porcine rotavirus disease is common in piglets under 8 weeks old, especially in cold season. High morbidity, low mortality and mild symptoms. There is no effective treatment.
Piglets aged 5-25 days are prone to white dysentery, which is endemic, with no obvious seasonality, moderate morbidity, low mortality, no vomiting and white paste-like loose stools. The treatment effect is better.
Piglet yellow dysentery mostly occurs in piglets less than the age of weeks, 1 ~ 3 days old, with high morbidity and mortality, yellow loose stool, less vomiting, rapid onset and often death without treatment.
Piglet red dysentery mostly occurs in piglets less than 3 days old, and piglets over 1 week old rarely get sick, and begin to excrete sticky feces, with red stools in the back row, occasional vomiting, acute course of disease and quick death. There is no effective treatment.
Pigs of 2-4 months old often occur in piglet paratyphoid, and there is no obvious seasonality, but they occur frequently in winter and spring, which is endemic or sporadic. Acute constipation has diarrhea first, then bloody stool and foul smell; Chronic constipation and diarrhea appear alternately, and the feces are gray, light yellow or dark green, with a foul smell. Drug treatment is effective.
Swine dysentery mostly occurs in piglets at the age of 2 ~ 3 months. The initial body temperature is slightly higher, and the feces contain a lot of mucus and blood, which is gelatinous. The onset season is not obvious, the spread is slow, the epidemic period is long, and it is easy to relapse after treatment. High morbidity and low mortality. During the epidemic period, the incidence of weaned piglets can reach 90%, and its mortality rate is generally around 30% under reasonable treatment. Treatment with Li Junjing is effective.
