A review of the latest research progress on 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.

Porcine edema is an acute, fatal disease of weaned piglets, mainly in newly weaned piglets, especially fast-growing and robust piglets. The onset is sporadic, only 1-2 hair diseases in a litter or a group of pigs, the onset is sudden, the initial body temperature rises, and then quickly drops to room temperature or low, often constipation. The characteristic symptom of this disease is edema, which is more common in the eyelids, head, neck, and even the whole body; Visceral edema is common in the stomach wall, especially the greater curvature, cardia and floor of the stomach, and the edema is incised, and there is a layer of transparent or brown-colored and reddish peptone between the mucosa and the muscular layer.

Edema is also seen in the mesocolon, mesenteric lymph nodes, and superficial lymph nodes. Sick pigs mostly show neurological symptoms such as blind walking or turning in circles, ataxia, spasms or convulsions, and then gradually develop into hindquarters paralysis and die in a coma within 1-2 days.

The pathogen of this disease, which is currently believed to be caused by pathogenic Escherichia coli, often lacks enteral adsorption factor, is hemolytic, and contains endotoxins and neurotoxins. In addition, feed sheets.

1. Too much concentrate, vitamin B or E, selenium and other minerals are deficient in this disease. Due to the sudden onset of the disease, the course of the disease is short, the pathogenic mechanism is not very clear, and the general effect is not obvious. At present, no effective preventive vaccine has been developed, and only the cause of the disease can be prevented.

1.Infected sows and infected piglets are the main sources of infection, and the bacteria are excreted in the feces, contaminating feed, drinking water and the environment, and passing through the digestive tract. Therefore, regular feeding of pigs with oxytetracycline, norfloxacin, ciprofloxacin and other drugs or microecological preparations can reduce the pathogenic bacteria in the pig intestine and reduce the pollution of the environment by the bacteria.

2.Piglets 3-5 days before and after weaning or transfer were fed drugs or microecological preparations to control the number of E. coli in the intestine of piglets.

3.Strengthen the feeding management of piglets before and after weaning, and do not suddenly change the feeding conditions when weaning. It is best to use compound feed, and add trace elements and vitamins in moderation, especially pay attention to adding selenium and vitamin E to the feed.

4.Weaned piglets should not use high-protein, high-energy feed, and properly control the amount of feed for piglets with large weight, so as not to cause indigestion, because excess nutrients to the hindgut, will cause E. coli to multiply in large quantities and promote the occurrence of diseases.

5.It is necessary to prevent indigestion caused by cold in weaning and turning piglets, causing intestinal microbial flora disorders and inducing E. coliosis.

It can supplement nutrition to pigs, improve the body immunity of pigs, and use drugs to carry out **, the best effect.

I think we must ask a more professional veterinarian to come to **, and we should also find out ** in time, and then prescribe the right medicine, so that the effect is better.

Be sure to pay attention to the choice of medicine, and at the same time you should go to the veterinarian for **, and to understand the symptoms of this disease, you must prescribe the right medicine.

New sub-organisms can be injected, and they can also be treated with drugs**, and magnesium sulfate can also be taken orally, which can help **, and attention should be paid to disinfection, and vaccines should also be injected, and the spread of the virus should also be noted.

You can give the piglets some rich protein and calcium things, you can supplement some trace elements, improve the immunity of piglets, it is best to choose breastfeeding, you can give the piglets to eat something good to digest and absorb, and you can also give the piglets some vaccines can play a preventive role.

When encountering such piglets, you can only give up, because such a disease is very serious, it is difficult to **, first of all, don't feed too much water to the pig at ordinary times, and don't let the weather be too hot.

Give the pig some medicine or ask the veterinarian to take a look. You can clean the pigsty, then ventilate it frequently, and feed the pigs some clean food.

First of all, we should provide a clean and comfortable environment to recuperate, and give the pig some relevant drugs, and the usual diet should be supplemented with more protein and water, usually the environment and temperature regulation of the pig house, and to ensure that it is clean, can be effectively prevented.

It must be dealt with in a timely manner, disinfected regularly, and a reasonable feed should be used, and sufficient nutrition should be added to the piglets, especially in the early stage.

First, the piglets are supplemented with selenium 1-3 days after birth. After weaning, piglets switch from liquid feed to solid concentrated feed, and the amount of food is too large, resulting in an imbalance in the piglet's intestinal microflora. The same frequency is higher, and the frequency is lower when the temperature is stable; Vitamin B and sodium selenite are added to the feed less frequently.

Edema disease is the main disease affecting the efficiency of pig farming and the main cause of piglet death. It is important to understand the pathogenesis of edema disease in piglets. These undigested feeds are also a source of nutrients for harmful bacteria to multiply.

After sodium acetate, we should try to extend the feed conversion time as long as possible to reduce the pressure of feed conversion. During this period, pathogenic E. coli will take the opportunity to invade the piglets, and the head of the diseased piglets will become obese and edematous, and the mortality rate can reach up to 50%, or even 80%. Asthma can be said to be a big killer of piglet health!

Its effect is to inhibit the proliferation of harmful bacteria. For example, swelling sickness is mainly caused by food problems. The onset of oncological diseases is divided into four stages:

1.Edema of gastric curvature.

You can anatomically see the occurrence of fundus edema. The first symptom of the pig is vomiting, which is temporary. Intestinal edema.

Currently, the toxins in the feed are absorbed by the intestines, causing transient diarrhea. Some people recover faster through life**. With the usual intramuscular injection of milk powder for storage vaccines.

2ml head for 7-11 days at a time, 2ml head at a time for 25 days, to prevent a failure of immunization, the lowest cost, pig edema is a regional fatal disease of pigs, and has a lot to do with the feeding of pigs. The main reason is that the piglets have a better quality diet and <>

Without a certain amount of nutrition, the quality of feed protein deteriorates, and the number of diseases is caused by E. coli. Coke. However, this e.

E. coli does not damage the gastrointestinal tract of pigs, but it can damage the brains of pigs. Pigs have neurological symptoms of encephalitis, which are easy to appear when they are relatively large, and you can find that the most important point is that the pigs with the best growth are the pigs with encephalitis, so they are also the most sad; Enterobacteriaceae iron preparations can also be injected into intramuscular pigs with the addition of 1 ml of 1 1000 sodium selenite. In 15-day-old piglets, selenium was supplemented twice, 2 ml head.

First of all, we must ensure the cleanliness of the environment, but also ensure good ventilation, and secondly, we must add some drugs to increase immunity in the feed, and also provide clean water, and also disinfect in the cage every day.

To keep the pig house clean, ventilate frequently, spray the pig house with disinfectant, give the pigs some medicine, and give the piglets nutritious food.

To ensure the cleanliness of the pigsty, to clean the pigsty in time, to strengthen ventilation, you can feed some antibiotics to the piglets, to feed the piglets some nutritious food.

It can be prevented with medication, or by observing the basic manifestations of the disease, but also by finding the source of infection, cleaning the pig house regularly, and paying attention to the spread of bacteria.
