    "Swine edema disease, also called enterotoxemia, hemolytic Escherichia coli toxemia, gastric edema, intestinal edema, gastrointestinal edema, piglet wobble, or paralytic poisoning. It is mainly characterized by the emergence of edema and neurological symptoms.

    After the pig became ill, edema appeared under the skin of the eyelid, conjunctiva, gums, face, neck, and abdomen, and severe edema appeared on the top of the head and even on the lower chest. When standing, the back of the bow trembles, the gait staggers, and it becomes unable to stand. The muscles tremble, and the limbs move like swimming, making hoarse screams. The temperature is normal or low. Those with short duration can die within a few hours.

    The disease mainly occurs during the late autumn and early winter season (October to early December), with the highest incidence in November. The pathogenic microorganism causing the disease is a specific serotype

    Of toxins produced by hemolytic E. coli. Hemolytic E. coli is present in the intestine, and the disease does not always occur. Toxic factors must be formed in the intestine and absorbed to a certain amount before they can develop disease. The ability of hemolytic E. coli to form toxins in the intestine is related to the body's resistance and surrounding environmental factors, especially when the feeding and management conditions are not good (such as single feed, lack of minerals and vitamins, etc.), it is easier to form toxins Then cause the disease. Judging from the age of the pigs, it usually occurs in piglets before and after weaning, especially the obese piglets are more susceptible to the disease, and the mortality rate is extremely high. Fatty pigs, sows, and Krone pigs can all develop the disease, and cure rates are low. Therefore, during the turn of autumn and winter, special attention must be paid to the prevention and treatment of this disease to avoid or reduce the incidence of this disease.

    prevention

    (1) Strengthen feeding management, often supplement feeds rich in protein and vitamins, pay attention to pig house cleanliness and hygiene, and often avoid the disease. Especially when weaning, we should pay more attention to the above problems. Do not abruptly wean, feed should be diversified, keep the feeding conditions gradually changing, so that the piglets have an adaptation process, and can play a more reliable preventive role.

    (2) 1.5 g of sulfamethoxine per head per day is taken 1 week before and 3 weeks after weaning to prevent the occurrence of this disease.

Piglets up to 10 kg are orally administered 10 g; pigs 11 to 20 kg are orally administered 20 g; pigs 21 to 60 kg are orally administered 30 g; pigs 31 to 40 kg are orally administered 40 g; 40 kg or more The pig takes 50 grams orally at a time. Once a day (in mixed feed), it can be used for five consecutive days to prevent it.

    (4) 50 grams of fresh Portulaca oleracea and 20 grams of Platycladus orientalis leaves (daily dosage per head), cut into fine pieces and fed in mixed feed, once a day in the morning and evening, for 5 consecutive days, the prevention effect is very good .

    treatment

    (2) Hydrocortisone injection, 5 mg per kg of body weight, once intramuscularly or intravenously, once a day for three consecutive days.

    (3) 15 ml of 10% calcium chloride, once in the vein of the ear, once a day for five consecutive days.
