7 confusing pig diarrhea diseases
1, Piglet white sputum:
It caused by pathogenic E. coli, mostly occurred in piglets 10 to 30 days old. It is endemic, seasonal is not obvious, the incidence is moderate, the mortality rate is not high, no vomiting, white or gray-white paste-like feces, body temperature is not high, the course of the disease is acute or subacute. It is effective with antibiotics or sulfonamides.
2, Piglet jaundice:
The pathogen is a certain serotype of hemolytic E. coli. Multiple within 7 days of age, morbidity and mortality are high. Sick pigs have less vomiting, yellowish dung, and the most acute or acute course. With gentamicin or chloramphenicol, combined with cardiotonic rehydration and other comprehensive treatment, the effect is better.
3, Piglet red cockroaches:
The pathogen is Clostridium perfringens type C, often occurs in piglets within 3 days of age, rarely onset more than 1 week old. Sick pigs occasionally vomit, red sticky feces, the most acute or acute course of disease, high mortality. The treatment effect of the disease is not good, the key lies in prevention, that is, intramuscular injection of 5 ml of C. clostridium vaccine in the sow 1 month before the birth of the sow, and injection of 10 ml half a month before the birth, can play a very good preventive effect.
4, Piglet paratyphoid:
It (also known as salmonellosis) mainly inflicted 2 to 4 months old piglets. No obvious seasonality, it is distributed in the region. The body temperature is slightly higher, showing acute septicemia and severe diarrhea. The chronic sputum is repeatedly squatted, and the skin may have purple spots. The necropsy can be found that the blind colon has irregular ulcers and pseudomembranes. The effect of treatment with chloramphenicol is very obvious.
The pathogen is swine dysentery. Pigs aged 2 to 4 days were frequent, and the seasonality was not obvious. Slow spread, long epidemic period, easy recurrence, high incidence, low mortality, normal body temperature, but slightly higher at the beginning of the disease, the faecal stool mixed with a lot of mucus and blood, often jelly-like. The lesions were mainly examined in the large intestine. The disease is better treated with sputum, sputum, and dinitroimidazole.
6. Porcine epidemic diarrhea:
It caused by the porcine epidemic diarrhea virus of the Coronavirus family. Pigs of different ages, breeds and genders can be infected, mostly in winter, especially in December and January. Young pigs exhibit diarrhea, and adult pigs only have vomiting and anorexia. The speed of transmission is fast, but the mortality rate is low. There is no specific treatment at present, and the general epidemic process lasts for 4 to 5 weeks and can naturally calm down.
7, Porcine transmissible gastroenteritis:
It caused by the porcine transmissible gastroenteritis virus of the Coronavirus family, pigs of all ages can occur. Piglets have a high mortality rate and very few pigs die. Common in the cold season, rapid spread and high incidence. At the beginning of the disease, vomiting, gray or yellow water-like dilute feces, sick pigs quickly lose weight, dehydration, most of the big pigs can recover in a short period of time. The treatment of this disease is not good, should focus on prevention, pregnant sows 4 to 15 days before delivery, muscle and nasal inoculation 1 ml of porcine infectious gastroenteritis attenuated vaccine; or after the birth of piglets, use pathogenic Oral immunization with attenuated vaccines, 1 ml per oral dose.
