LF inhibited PEDV replication. A Schematic diagram depicting the antiviral effects of lactoferrin when pre-incubated with cells. B–D Quantification of viral RNA in cells (B) and viral titers in culture supernatants (C and D), determined using RT-qPCR and plaque reduction assays, respectively. E RT-qPCR analysis of viral RNA loads in feces from different piglet groups. F–H RT-qPCR and Western blot analyses showing viral RNA (F) and protein levels (G and H) in the jejunum and ileum of piglets from various groups. **P < 0.01.
