Problems solved by technology

[0007] The purpose of the present invention is to: for the control of porcine epidemic diarrhea in the current large-scale pig farms, there is no fully effective vaccine and drug treatment method, and the effect of refeeding is not ideal due to the unqualified selection technology of disease materials, etc. defect, provide a simple and effective method for preventing and controlling porcine epidemic diarrhea

Embodiment 1

[0022] The breeding pigs in the pig farm are stable, and the piglets in the farrowing house continue to be sick for a long time. The single-day death is not large, but the cumulative loss over a long period of time is relatively large, indicating that the virulence of the epidemic strains is weak, and the health and immune protection of the breeding pigs are better. At this time, use The refeeding operation improves the protection of sows’ maternal antibodies to piglets and promotes the stability of the whole group. The refeeding method is as follows:

[0023] (1) Collection of disease materials: Slaughter the piglets within 24 hours after the onset, disinfect the abdomen with tincture of iodine and deiodine with alcohol, open the abdomen but do not cut the intestinal tube, and find the duodenum and The approximate junction of the jejunum is ligated with a suture, and then the end of the ileum is ligated with a suture at the ileocecal junction, and finally the small intestine b...

Embodiment 2

[0029] When the pig farm has just started to get sick and the disease spreads quickly, it means that the virulence of the epidemic strain is strong, the health of the breeding pigs is not good, and the immune protection is poor. Feeding and returning methods are as follows:

[0030] (1) Collection of disease materials: Slaughter the piglets within 24 hours after the onset, disinfect the abdomen with tincture of iodine and deiodine with alcohol, open the abdomen but do not cut the intestinal tube, and find the duodenum and The approximate junction of the jejunum is ligated with sutures, and then the end of the ileum is ligated with sutures at the ileocecal junction, and finally the small intestine between the two ligation points is cut off in the operating room, and the intestinal tube and intestinal contents are taken out and placed in the in a sterile container.

[0031] (2) Treatment of disease materials: After cutting and grinding the collected piglet intestines and intest...

Embodiment 3

[0036] The outbreak of PED in pig farms caused heavy losses, which indicated that the prevailing virus strains were extremely virulent, and the health and immune protection of breeding pigs were poor. In order to control the disease as soon as possible, the whole farm was adopted for open feeding. The feeding method is as follows:

[0037] (1) Collection of disease materials: Piglets that died or were slaughtered within 24 hours after the onset were collected. After the abdomen was disinfected with tincture of iodine and deiodized with alcohol, the abdomen was cut open without cutting the intestinal tube, and ten pigs were found along the duodenum. The approximate junction of the duodenum and the jejunum is ligated with a suture, and then the end of the ileum is ligated with a suture at the junction of the ileocecum, and finally the small intestine section between the two ligation points is cut off in the operating room, and the intestine and bowel are taken out The contents ar...

Abstract

The present invention discloses a method for preventing and controlling porcine epidemic diarrhea. A return feeding method is adopted, a natural infection method is simulated, feces or intestinal tract and intestinal contents of porcine epidemic diarrhea virus (PEDV) infected animals are crushed, ground and diluted, then antibiotics are added, non-infected animals are infected through mouths, the total group can be infected in the same period, mucosal immunoreaction is stimulated to be generated, IgA antibodies are generated, so that the anti-PEDV effect is achieved, and finally the pestilence can be controlled. The return feeding method is tried out through a small group, the specificity sIgA antibody level is detected by using an indirect ELASA method, the return feeding dosage is determined according to antibody level change conditions, then large group return feeding is carried out, and return feeding failure caused by the fact that the return feeding dosage is not exact in the past is largely reduced. According to the method, the porcine epidemic diarrhea can be effectively prevented and controlled, the spread of diseases can be rapidly and effectively controlled especially when the epidemic diarrhea diseases outbreak, and greater economic losses and disease outbreak again can be prevented; and the return feeding process is simple and easy to operate, and cost is low.

Description

technical field [0001] The invention specifically relates to a method for preventing and controlling porcine epidemic diarrhea, which is suitable for preventing and controlling porcine epidemic diarrhea in large-scale pig farms. Background technique [0002] Porcine Epidemic Diarrhea (PED) is an infectious disease caused by Porcine Epidemic Diarrhea Virus (PEDV). PEDV is an RNA virus that belongs to group 1 of the Coronaviridae family, and coronaviruses are highly mutated viruses. PED virus was first isolated and identified in Europe in the 1970s, and was introduced into China, Japan, and South Korea in the 1990s. Before 2000, PED had been reported in the Philippines, Thailand, and Vietnam. Pigs of all productive ages are susceptible to PEDV, with the most severe damage in farrowing and nursery piglets, manifested by high mortality and morbidity. Reports from Asian countries show that once PED has never occurred in pig farms, the mortality rate of piglets within 24 hours a...
