The aim of this study was to assess and compare the safety and efficacy performance of two commercial vaccines registered in Canada, under field conditions, on a commercial farm where E. coli was found to be the source of diarrhea.

Neonatal diarrhea currently continues to be one of the pathologies that has the highest cost for producers and E. coli is still one of the primary triggers among the infectious agents that cause neonatal diarrhea in pigs. The current study shows differing diarrhea-preventive effects of the two vaccines evaluated. Thus, Vaccine A (SUISENG®) exhibited a 6-fold lower incidence of diarrhea in suckling piglets from gilts vaccinated with it than in suckling piglets from gilts vaccinated with its competitor, Vaccine B. Moreover, Vaccine A (SUISENG®) showed greater safety than Vaccine B by causing a smaller increase in post-vaccination body temperature and by not showing any local or general type reactions, which may end in abortion and the resultant economic loss to the producer.
