Diarrhea in pre-weaning piglets is one of the most common diseases in modern pig production, causing high mortality, reducing growth rate and increasing treatment costs. This prospective study on a commercial pig farm was conducted to identify the diarrhea prevalence, the factors associated with diarrhea, and the effect of diarrhea on weaning weight of piglets. The results showed that the proprtion of cumulative diarrhea for 21 days in suckling piglets was 36.70% (95% CI 32.91-40.62) with a mortality rate of 0% (95% CI: 0-0.59). Neonatal piglets experienced diarrhea from 1 day of age (11.86%), peaked at day 5 (22.6%), then gradually decreased and kept at a low level from 11 days of age to weaning. There were 3 factors associated to diarrhea in suckling piglets including birth weight of piglets, diarrhea inflicted sows and metritis inflicted sows. The factors of diarrhea duration and birth weight were related to maternalassociated weaning weight of piglets.
