How to distinguish the causes of edema disease in piglets

** is a disease caused by hemolytic Escherichia coli. Symptoms include eyes, face, conjunctiva, hoarseness, decreased appetite, no obvious change in body temperature, unsteady standing, ataxia, limb swimming, muscle tremors all over the body, and finally death from coma, with a case fatality rate of about 90%.

The cause of the disease is due to the toxin produced by pathogenic E. coli, which leads to an acute sporadic disease in weaned piglets. The main symptoms are sudden onset, malaise, decreased desire to eat, limb movement disorders, ataxia, some sick pigs do circle movement or blind rushing, forelimbs kneeling, hind limbs erect, screaming, limbs stroke, foaming at the mouth. Edema of the face and eyelids.

It may be affected by E. coli, other toxins and other factors, or the feeding conditions are not up to standard; Once such a disease appears, these pigs will have hoarseness, and the spirit is relatively poor, and at the same time the appetite will also decrease, and then the body temperature will not change significantly, and there may be fainting and death.

First of all, there will be chills, shivering, and it will also lead to a decrease in appetite or loss of appetite, and it will also lead to diarrhea, and there will also be an increase in body temperature, as well as hoarseness, sensitive to touch, and other symptoms. The cause of the disease is due to the influence of the external environment, and it also leads to a decline in the function of the intestines and a decrease in resistance to diseases.

There will be depression, body trembling, mild diarrhea, weakness of limbs, not eating food, if there is such a situation, then it means that the situation is now very serious, must be timely**.

Piglet edema disease mostly occurs between 40 and 70 days of age.

Piglets are born to 1 week after weaning 2 weeks this stage, this period is a critical period of pig growth, most of the infectious diseases, some parasitic diseases and nutritional deficiencies caused by improper feeding management can pose a threat to piglets, causing morbidity, pig edema disease is caused by pathogenic Escherichia coli infection weaned piglets more intestinal toxemia, although the incidence is not high, but the mortality rate caused by the onset of the disease is higher, the highest mortality rate is as high as more than 80%.

The E. coli that causes swine edema disease is mainly hemolytic E. coli, and on the basis of the vigorous reproduction of beneficial intestinal flora, Enterobacter macrobacterium usually does not show obvious pathogenic ability, and swine edema disease often occurs in piglets with faster growth rate and better physical fitness.

Identification of common diseases in piglets

1. Piglet dysentery: it mostly occurs in young pigs within 1 week of age.

2. Piglet dysentery: high incidence of piglets at birth.

3. Swine fever: piglets from suckling pigs to piglets before and after weaning can be infected, and the younger the diseased pigs, the faster they die.

4. Porcine erysipelas: mostly caused by the disease of sows.

5. Porcine lung disease: suckling pigs rarely occur, and piglets can be infected during the epidemic period after weaning.

6. Streptococcus suis: the susceptibility of sick piglets is high, and septic often leads to rapid death of piglets.

7. Paratyphoid fever in piglets: it mostly occurs in unvaccinated piglets from 2 months to 4 months old, and it rarely occurs in piglets within 1 month of age.

8. Swine flu: the incidence of piglets is low, and the incidence of weaned piglets is high.

9. Haemophilus suis disease: often secondary after pigs are infected with influenza.

10. Congenital muscle tremor in piglets: the disease occurs scattered in some areas, often occurs in the whole litter, and the first pigs are often starved or crushed to death.

11. Porcine foot-and-mouth disease: young pigs have a high mortality rate after infection, and suckling pigs often do not see blister symptoms when infected with this disease, and often die of acute gastroenteritis or myocarditis.

12. Infectious gastroenteritis: high mortality rate for young pigs within 10 days of age.

13. Porcine lung nematode disease: piglets infected before weaning can die in large numbers. It's fighting.

14. Swine ascariasis: suckling pigs can be infected after 1 week of age.

15. Porcine cysticercosis: piglets can be infected in endemic areas, but few clinical symptoms appear.

16. Piglet anemia: It is one of the common diseases of suckling piglets between 2 weeks and 4 weeks old, and pigs from 3 to 10 days old can die suddenly.

17. Rickets (osteomalacia): caused by calcium and phosphorus deficiency or imbalance, of which congenital rickets is caused by sow's nutritional deficiency leading to piglet embryonic bone dysplasia.

1. Lie on your side with your legs paddling.

2. Hindquarters paralysis, head angular arch reflexion.

3. Intestinal interstitial edema and intestinal serous congestion and bleeding.

4. Mesenteric edema of the large intestine, lymph node edema and congestion.

Porcine edema disease is common in piglets around 7 days after weaning, causing symptoms such as paralysis of the limbs, waddling gait, spasms and coma in piglets.

It is mainly characterized by edema and neurological symptoms, sudden onset, red eyes, rapid death and high mortality, some sick pigs foam at the mouth, limbs are weak when walking, ataxia, blind forward or circle. The eyelids, gums, neck, conjunctiva, scalp, and prefemoral subcutaneous edema of the sick pig are highly edematous, and clear and colorless jelly-like fluid accumulates. The incidence rate is 10% to 30%, but the case fatality rate is as high as 80% 100%, which brings great harm to the pig industry.
