0,05).The objective of this study aimed at investigating the status of pig production and farmhygiene application, determining the risk factors associated with the prevalence of PorcineEpidemic Diarrhea (PED) virus in the small scale pig household farms in Soc Son district in2016. The studied results showed that there were 55.1% of the pig households used industrialfeed, 100% of pig households used drill-well water for raising pig and 67 % of households dailycleaned pig pens. However, there were 24% of pig households discharging the un-treatedwastewater and wastes directly into common environment
91% of the pig households addedantibiotics into the pig feed
56.8% of the pig households did not provide mineral premix andvitamins for pigs and 100% of pig households did not have PED vaccine. The prevalence ofPED virus from the diarrheal pig feces samples was 6.6% (8/121). The associated factorsmight play the important role in increasing the risk of diarrhea from 2.47 to 5.37 times (p
