1Control pigs remained negative for PEDV throughout the duration of the study.
2Ct, cycle threshold. Ct value ≥35 is considered negative for PEDV.
3Positive pigs out of total pigs swabbed at that dpi. Pigs were considered positive for PEDV presence in feces when Ct <35.
4Positive pigs were those that PEDV nucleic acid was detected in the jejunum.
5Positive pigs were those that PEDV protein was detected in the jejunum.
a,bMeans without a common superscript differ (P ≤ 0.05).
