With the advent of winter, the external climate has undergone tremendous changes. Cold weather will bring severe cold stress to the pigs. If the management is not strengthened, not only will the growth rate of the pigs be slowed, but the pigs will even develop diseases. Death will cause great economic losses to pig production. To this end, the newspaper launched on the same day a series of special articles on the prevention and control of common diseases of winter pigs, focusing on the prevention and treatment of winter swine diseases and providing reference for large farms (households) for reference.
Disease characteristics
The climate in the early winter is variable and the temperature difference changes greatly. The piglets are very susceptible to edema disease. The pathogen of the disease is E. coli. This disease is also called enterotoxicosis, gastrointestinal edema, and piglet rocking. Shortly after the pigs were born, there was a large number of E. coli parasites in the intestine. When the pig suddenly suffers from cold stress, its body resistance decreases, and E. coli enters into the space and secretes large amounts of toxins that damage the body of the pig and cause the disease. The disease is characterized by the occurrence of edema and neurological symptoms. The mortality rate of this disease is very high in the early winter, and the incidence of the more obese pigs is higher.
Clinical symptoms
Swine swollen eyelids, reddened skin, tremor, and swaying at the beginning of the disease; middle cap and neck skin were highly swollen and mucus flowed; late systemic height edema, paralysis of the front and rear limbs, recumbency on the ground, paralysis or extremities Swim like a swim. If the control is not timely, the mortality rate is high.
Precaution
1. Strengthen the feeding and management of the pigs before and after weaning, feed materials early, and train feed intake so that weaned pigs can adapt to an independent life.
Second, weaning should not be too sudden, do not suddenly change feed and feeding methods.
Third, the amount of feed increased gradually to prevent a single feed, increase vitamin-rich feed.
Fourth, to improve feeding and management, 7 days after the birth of the pig, should start using more feed containing protein, while sucking, let it adapt to artificial feed as soon as possible. The feed used must be fresh and should be fed on a small number of occasions to promote gastrointestinal function.
Fifth, in the early winter, we must strengthen the management of the pigs so that the pigs do not catch cold. The pigs should not be weaned at weaning, feeds should be diversified, and the pigs should be sanitized and sanitized on schedule.
Six, 14 to 18 days of age piglet injection edema disease polyvalent inactivated vaccine, to prevent the occurrence of this disease has a significant effect.
VII. The initial dose of appropriate diarrhoea and salt laxative promotes gastrointestinal motility and secretion to discharge intestinal contents. Common antibacterial drugs can also be used.
Control methods
First, the principle of treatment of edema disease is a comprehensive symptomatic treatment, that is, anti-bacterial anti-inflammatory, cardiac, detoxification, diuretic.
Second, the use of cardiac medicine to promote blood circulation, heart diuresis, promote the discharge of edema fluid, reduce the burden on the heart.
Third, due to lack of selenium will exacerbate the occurrence of swine edema disease and exacerbation of the disease, the application of selenium supplement therapy to improve the cure rate.
Fourth, use 10% Sulfathiazole 30 ml, one intramuscular injection, 2 times a day for 3 days.
Five, with 50% glucose solution 40 ml, 5% anti-bad thrombus solution 10 ml, chloramphenicol injection 500,000 international unit mixed intravenous injection once a day for 3 days.
