Prevention and treatment of enterotoxemia in sheep

Sheep enterotoxemia, also known as soft kidney disease, fast epidemic, etc., is an acute infectious disease of sheep caused by Clostridium welchii multiplication and toxin production in sheep intestines, characterized by acute onset, quick death and postmortem kidney softening. It mostly occurs at the turn of spring and summer and in autumn, especially in 2-12-month-old sheep. Let's take a look at the prevention and treatment of sheep enterotoxemia.

Popular characteristics

Clostridium welchii is a common bacteria in soil and also exists in sewage. Usually sheep only feed on forage grass or drinking water contaminated by spores, and the spores enter the digestive tract, which generally does not cause disease. When the feed suddenly changed, especially Chang changed from eating hay to eating a large number of cereals or green, succulent and protein-rich forage, resulting in a decline in resistance and digestive dysfunction of sheep. Clostridium welchii type D propagates rapidly in the intestinal tract and produces a large amount of e-protoxin. after trypsin activation, the toxin enters the bloodstream, causing systemic toxemia and causing shock and death. The occurrence of enterotoxemia in sheep often shows a certain seasonality, which is more common in pastoral areas during the period of grazing green at the turn of spring and summer and in a period of time after forage seeds in autumn, while in agricultural areas, it is more common in the harvest season or when eating a large amount of protein-rich feed. It's generally sporadic.

Clinical symptoms

Sheep enterotoxemia occurs suddenly, sick sheep show abdominal pain, abdominal distension symptoms, sick sheep often stand apart from the group, lying on the ground can not afford or run alone. Dying period occurs intestinal ringing or diarrhea, the discharge of yellowish brown water sample sparse baking feces. Trembling, grinding teeth, head and neck back, mouth and nose foaming, died in a coma. Body temperature is generally not high, blood, urine routine examination of blood sugar, urine sugar rise phenomenon.

Pathological changes

The pathological changes of enterotoxemia in sheep are mainly limited to the digestive tract, respiratory tract and cardiovascular system. There is undigested feed in the true stomach, and the intestinal tract, especially the small intestine, is congested and bleeds. In severe cases, the whole intestinal wall is blood red or has ulcers. Pulmonary hemorrhage, edema, kidney softening like mud, is generally considered to be a postmortem change. Body cavity effusion, heart dilatation, endocardial and epicardial bleeding.

Prevention and cure method

The main results are as follows: 1. The frequently affected areas are regularly inoculated with "sheep fast epidemic, enterotoxemia, shock triple vaccine" or "sheep fast epidemic, enterotoxemia, sudden shock, lamb dysentery, black plague vaccine" every year. Sheep, no matter big or small, are injected subcutaneously or intramuscularly with 5 milliliters. Immunity is produced 2 weeks after vaccine injection, and the protection period is up to half a year.

2. Strengthen feeding and management, grab green and stubble in agricultural and pastoral areas in spring and summer, avoid excessive intake of seed-bearing grasses in autumn, and transfer to high dry pastures in time when the disease occurs.

3. The course of enterotoxemia in sheep is short, and it is often too late to treat it. When there are cases in sheep for a long time, only 10-20% lime milk 500-1000 ml can be taken for prevention.
