Low incidence and high mortality of edema disease how to prevent and cure edema disease of piglets

1. The harm of piglet edema disease: 1. Piglet edema disease is an infectious disease characterized by edema and highly lethal caused by hemolytic Escherichia coli. Strong and well-growing piglets occur frequently, which brings serious losses to the pig industry. 2. The disease occurs in all seasons, but the incidence will increase in spring and autumn. 3. The incidence of edema disease in piglets is not high, but the fatality rate is high. Some piglets even die suddenly without any symptoms, which is one of the most serious diseases of weaned piglets.

Piglets

Second, the causes of edema disease of piglets: 1, weaning stress, environmental and climate change, long-distance transportation, lax disinfection and other factors can cause edema disease of piglets. two。 The pathogenesis of edema disease is complex. It is generally believed that pathogenic Escherichia coli invades the intestinal tract and propagates in large quantities to produce toxins. After the toxins are inhaled into the blood by the intestines, they cause enterotoxemia and edema disease.

3. Preventive measures for edema disease of piglets:

1. Prevention of inactivated vaccine against edema disease in piglets over 25 days old

two。 The material must be replenished as soon as possible. The piglets began to feed at the age of 10 days, and early feeding was beneficial to improve the digestive organs of piglets, promote gastrointestinal development and establish normal gastrointestinal biota as soon as possible.

3. Castration and epidemic prevention. Castration is carried out about 10 days before weaning, so that the stress is small and the knife edge heals quickly. No epidemic prevention was carried out within 10 days before weaning and 20 days after weaning, but abstinence, castration and epidemic prevention were carried out simultaneously.

4. Weaning at the right time. First of all, do not blindly pursue early weaning. If the conditions are general, the weaning time should be 6 Mel and 7 weeks old. In addition, it should be flexibly mastered according to the individual situation of piglets, feeding conditions, weather conditions and so on.

5. Weaning method. It is best to use the "mother does not move, one-time weaning method" to drive away the sows and keep the piglets in the original circle, so as to reduce the stress caused by weaning to piglets.

6. Feed properly. After weaning, the feed quality of piglets should be guaranteed. The piglets were still fed with pre-weaning feed in the first 10 days, a small amount of regular feed and normal feeding after 15 days, which could increase the adaptability of piglets to the change of feed. In addition, green and succulent diets such as vegetable leaves were not fed within 20 days after weaning to prevent piglets from diarrhea and reduce disease resistance.
