Snippet: Pregnant sows are suitable models for evaluating the effectiveness of inactivated PEDV vaccines in target populations, such as neonatal piglets, because transfer of maternal antibodies to piglets via colostrum may play an important role in the development of protective immunity against PEDV in sucking piglets [26] .

Document: Pregnant sows are suitable models for evaluating the effectiveness of inactivated PEDV vaccines in target populations, such as neonatal piglets, because transfer of maternal antibodies to piglets via colostrum may play an important role in the development of protective immunity against PEDV in sucking piglets [26] . However, considerations of size of litter, housing, and reproduction have limited their use in vaccination experiment. And the correspondingly higher cost associated with housing and experimentation is needed. Therefore, in the present study, we used growing pigs to evaluate the protective efficacy of our experimental vaccines, because pigs of all ages are susceptible to PEDV infection [8] .
