Pigs with multiple edema can not stand in autumn and winter to prevent swine edema disease.

Swine edema disease, also known as enterotoxemia, gastric edema, intestinal edema, gastrointestinal edema, swinging pig disease, paralytic poisoning and so on. It is characterized by edema and neurological symptoms. After the pig fell ill, edema appeared in the eyelid, conjunctiva, gingiva, face, neck and abdomen, as well as severe edema on the top of the head and lower chest. When a pig stands, his bow shivers, his gait stumbles, he gradually becomes unable to stand, his muscles tremble, his limbs fall to the ground, he screams hoarse, and his body temperature is normal or on the low side. Those with a short course of disease will die within hours.

The disease mostly occurs in late autumn and early winter, and is the most common in November. The pathogenic microorganism causing swine edema disease is the toxin produced by hemolytic Escherichia coli with specific serotype. Hemolytic Escherichia coli is present in the intestines of all pigs, but not necessarily the disease. It takes a certain amount to get sick. Whether hemolytic Escherichia coli can form toxins in the intestine is related to the resistance of pigs and the surrounding environment, especially when the feeding conditions are not good, such as a single feed, it is easy to form toxins, and then cause the disease. From the perspective of pig age, piglets that mostly occur before and after weaning, especially fat piglets, are more prone to disease and high mortality. Fat pigs, sows and Dakelang pigs also developed the disease, and the cure rate was low. Therefore, in the autumn and winter season, pay attention to the prevention and treatment of edema disease, can avoid or reduce the occurrence of the disease.

Prevention of swine edema disease

(1) strengthen feeding and management, often supplement protein and vitamins, and keep the pig house clean and hygienic. Pay more attention to it, especially when the piglets are about to be weaned. The weaning should not be sudden, the feed should be diversified, and the feeding conditions should be changed gradually so that the piglets can adapt.

(2) one week before weaning and three weeks after weaning, each piglet was given 1.5 grams of sulfamethazine daily to prevent edema disease.

(3) cohosh, tangerine peel, Chuanlian, Poria cocos, plantain seed, alisma alisma, Scutellaria baicalensis Georgi, Shuanghua, Chuanpu, Zicao, Chuanjun, 200 calcium hydrogen phosphate and 550 mirabilite. Finely minced, mix well and set aside. 10g for piglets within 10kg, 20g for 20kg, 30g for 21ml, 40g for 30kg, 40g for 40kg and 50g for more than 40kg Once a day (in mixed feed) for five days.

(4) 50 grams of fresh purslane and 20 grams of Platycladus orientalis leaves (dosage per day), cut into fine powder, mixed in the feed, fed once in the morning and evening every day for 5 days, the effect is very good.

Treatment of swine edema disease

(1) 30 ml of 10% sulfathiazole was injected intramuscularly twice a day for five days. The doubling dose can also be injected into the abdominal cavity once a day for five consecutive days.

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

(3) 15 ml of 10% calcium chloride was injected intravenously once a day for five days.

(4) 40 ml 50% glucose solution and 10 ml 5% ascorbic acid solution were mixed and injected intravenously. Once a day for three days.
