How to prevent and cure red dysentery of piglets with high mortality rate of bleeding and sparse stool

Piglet red dysentery is enterotoxemia caused by necrotic intestines. The disease occurs mainly in 1-3-day-old piglets. Piglets infected with red dysentery will have intestinal necrosis and excretion of dilute faeces. Once found, they should be treated immediately, otherwise they will die in a large area. Because of the acute onset of piglet red dysentery, short course of disease and high mortality, treatment is urgent.

Piglets

The pathogenic bacteria of piglet red dysentery widely exist in human and animal intestines and soil, especially in the intestinal tract of infected sows, which can be excreted with feces and pollute the nipples of piglets and lactating sows. Newborn piglets are infected when they eat breast milk or swallow the bacteria from the contaminated ground, and the bacteria enter the jejunum to produce strong exotoxins, resulting in congestion, bleeding and necrosis of the injured intestinal wall, which leads to diarrhea and death of piglets.

1. Emergency drug treatment

After birth, piglets were given 0.2 ml of 25% chloramphenicol or 0.1 g of oxytetracycline 2-3 times a day for 3 days; after onset, 0.2-0.4 ml of 25% chloramphenicol injection and 200 mg of flavamidine were taken orally 3 times a day for 3 days.

2. Preventive methods

Red dysentery of piglets is mainly prevented. At present, the immune procedure of inactivated vaccine of red dysentery in piglets is as follows: pregnant sows are injected intramuscularly about one month and half a month before delivery, 5-10 milliliters each time. Sows that give birth continuously can be injected once half a month before delivery.
