How is edema disease caused in dead pigs? What is the best treatment to achieve?

Porcine edema, also known as gastric edema, is a small porcine enterotoxemia caused by hemolytic E. coli infection in pigs. The disease occurs mostly in weaned piglets, and occurs in fattening and fattening piglets, especially piglets, and occurs frequently in April-May and September-October every year. Pig farm sanitation should be done well, clean the pig house in time, and ensure that the pig house is clean and dry; The barn should be ventilated; Disinfect the barn regularly to minimize the retention of pathogens in the barn; Be aware of the weather changes and keep warm.

The edema disease of a dead pig is caused by the intestines caused by food, and we can give him some food improvements.

1. In piglets 1 week before weaning and 2 weeks after weaning, intramuscular injection of histamine globulin 2ml, once a week, or 1 week before weaning and 3 weeks after weaning, sulfadimethylpyrimidine is taken internally every day, and sulfonamides, garlic and other drugs can also be used for prevention in the onset season.

2. Use 15-25g of salt laxative (magnesium sulfate) for oral administration; Temporarily controlling or drastically reducing the amount of feed at different times, reducing the amount of feed to per piglet per day at weaning, and slowly increasing to sufficient after about 1 week, is a relatively successful prevention method.

**A combination of Chinese and Western and symptomatic methods** can be used to promote anti-allergies, eliminate edema and inhibit intestinal pathogenic bacteria, and should be diagnosed as soon as possible. Sulfadiazine sodium, 6-methoxysulfadiazine, enrofloxacin, chloramphenicol, kanamycin sulfate have the best effect on this disease, and the effect should be better when combined with sodium selenite VE, and dexamethasone can be used appropriately according to the condition to obtain satisfactory results.

** It is necessary to advocate the use of integrated prevention and control methods as early as possible. Once piglet edema is found, the whole litter and the whole group should be medicated, especially for the infected pigs that do not show clinical symptoms, in order to gain more time.

It is necessary to increase the content of multivitamins and selenium in the feed to improve the level of anti-stress.

Antimicrobial susceptibility tests should be conducted, antimicrobial drugs should be used in a targeted manner, and dexamethasone, hypertonic glucose, etc. should be used to strengthen anti-inflammatory and detoxification**.

Intravenous injection and intraperitoneal injection are more effective than intramuscular injection, and reduce dietary protein, which is conducive to disease control.

1.Do a good job of replacing the feed transition. The piglets transferred from other places should try to keep using the feed and feeding methods of the origin for more than 1 week, and then gradually change to feed the feed of the field, so that the piglets can gradually adapt.

2.Pay attention to the proportion of protein in the diet, and feed with full price. Avoid a single diet or high protein, and provide an appropriate amount of green feed, minerals and trace elements.

3.The barn should be kept clean and dry, and the piglets should be exercised properly to enhance disease resistance.

4.Each new piglet should be fed with compound acid preparation in drinking water for 7 days to achieve the purpose of preventing edema in piglets.

5.Do a good job of feeding before weaning to strengthen the gastrointestinal exercise of piglets. Weaning should not be too abrupt so that the feeding conditions change gradually.

Reduce the protein content in compound feed by 1% to 2% before weaning (or add roughage to piglet feed), take restricted feeding for 3 5 days after weaning, and then gradually transition to ad libitum feeding. For piglets suspected of edema, adding haloperic acid or sulfadiazine to the feed according to the preventive amount for 1 week can effectively control the occurrence of edema.

6.Selenium and iron supplementation were strengthened during lactation, and selenium supplementation was injected intramuscularly with 1 ml of sodium selenite solution at 3 to 5 days old in piglets, and then injected with 1 ml at 60 days old; Iron supplementation is used to inject animal blood and iron dextran at the age of 3 to 4 days to prevent the occurrence of edema in piglets.

The best principles for edema disease are desensitization, cardiac strengthening, bacteriostatic, diuretic, and swelling.

Desensitization can be done with hydrocortisone or dexamethasone, diuretic furosemide (nitrofuranine) or dihydrogram urinary plug, antibacterial sulfonamides are preferred; Secondly, enrofloxacin, lincomycin, etc., and glucose, sodium coffee, selenium and other auxiliaries can be selected

1) Immediately after the onset of the disease, change to feed with high digestibility, and add drugs to the feed.

2) Individual**: 10 20 ml of 10% sulfadiazine sodium injection, 50 ml of 50% hypertonic glucose injection, intravenous injection, once a day, for 2 3 days, long-acting oxytetracycline, enrofloxacin and other intramuscular injections, 2 times a day, for 2 3 days; Or 50% glucose solution 20 40 ml, full edema reduction according to the instructions for use, vitamin B 12 ml, inosine 2 ml, 20% sodium coffee 2 ml, mixed once intravenously. When the neurological symptoms are severe, sedatives such as chlorpromazine hydrochloride and analgin can be injected.

Use something good for water, such as kudzu.
