Symptoms, prevention and treatment of edema disease in piglets

Piglet edema disease is a week-long disease of weeding in pig farms. Generally, piglets who have just been weaned have a sudden onset of disease, head, face and eyelid edema, and sometimes water all over the body. Pressing with their fingers will leave a mark, and often they will die before treatment. So how to prevent and cure piglet edema disease? Let's take a look.

1. Causes of edema disease in piglets

1. Germs. The pathogen of edema disease in piglets is a neurological syndrome caused by a blood toxin produced by hemolytic Escherichia coli.

2. Improper feeding: the pens where piglets grow are dark and damp, poor hygiene and incomplete disinfection, which can easily lead to edema disease in piglets.

3. Stress factors. Edema disease in piglets may be caused by some stress factors, especially weaning, climate change, feed mutation, long-distance transportation and immune vaccination, which can cause indigestion and diarrhea in piglets. lead to the imbalance of normal intestinal flora and the proliferation of hemolytic Escherichia coli to produce toxins.

4. Digestive system. The digestive organs of piglets are not fully developed, and the small intestine and pancreas secrete less digestive enzymes, which can not completely digest and absorb nutrients in feed, especially proteins, etc., and the undigested proteins become a good medium for hemolytic Escherichia coli. Hemolytic Escherichia coli produces a large number of toxins and forms pathogenic factors.

Symptoms of edema disease in piglets

The clinical symptoms of edema disease are common in the face, eye face, conjunctiva and gums, sometimes affecting the subcutaneous part of the neck and abdomen, edema, hoarseness, sudden onset, mental depression, loss of appetite or lack of food. There is no obvious change in body surface temperature, often stand unstable, whole body muscle tremor, some piglets appear empty chewing, tongue protruding out of the exit can not retract and be chewed, and finally coma death, the mortality rate is very high, about 90%.

III. Prevention and control measures

First of all, it is necessary to strengthen the feeding management, to ensure that the pig houses are dry, clean and permeable, to disinfect the pens and raising equipment regularly, and to change the disinfectants in a timely manner to prevent the bacteria from developing drug resistance. To do a good job of immunization, intramuscular injection of trivalent inactivated vaccine 2mL of Escherichia coli K88, K99 and 987p in sows 40 and 15 days before parturition, and Escherichia coli trivalent inactivated vaccine 2mL in 14-20 days could significantly reduce the incidence of edema disease. For piglets to be weaned at the right time, it is appropriate to be weaned at the age of 35 days, gradually reduce the number of times of weaning, not abruptly weaning, and complete the feed formula to increase the content of minerals and vitamins. Ensure that the feed is fresh and mildew-free.
