Utilization of multivalent vaccine on sows ante partum for the prevention of piglet enteritis

다국어 초록 (Multilingual Abstract)

Three swine farms which were suffering from slight economic loss due to suckling piglets’ diarrhea, were selected to apply commercialized multivalent vaccine for sow use; SUISENGⓇ (Hipra, Spain). Farms were pre-diagnosed with clinical symptoms and molecular detection of C. perfringens Type A and C and E. coli pili by PCR. Sows were vaccinated twice 2 ml of the vaccine at 6 and 3 weeks ante partum intramuscularly according to the manufacturer’s instruction. All vaccinated sows did not show any adverse reaction or clinical signs; hypersensitivity, fever, granuloma or abscess on the in-jection site, appetite loss, and so on. Also, no reproductive disorder was appeared in vaccinated sows compared with non-vaccinated control sows. The results suggested that piglets born from vaccinated sows show significantly better performance in regard of the diarrhea index and mean daily weight gain compared with piglets from non-vaccinated sows. Therefore, the commercial vaccine for the prevention of neonatal diarrhea is found to be effective in reducing diarrhea in the first suckling period of piglets after birth.
