    Snippet: In the present study, the levels of PBA and LMFY in the PED-positive herds did not decline during the PED epidemic. A previous observational study indicated that only pregnant sows and gilts infected with PED at 0-30 days of pregnancy had smaller litters, whereas those infected at other points during the gestation period were not affected by PED [11] . If litter sizes are only reduced by PEDV infection within a particular gestational stage, the c.....
    Document: In the present study, the levels of PBA and LMFY in the PED-positive herds did not decline during the PED epidemic. A previous observational study indicated that only pregnant sows and gilts infected with PED at 0-30 days of pregnancy had smaller litters, whereas those infected at other points during the gestation period were not affected by PED [11] . If litter sizes are only reduced by PEDV infection within a particular gestational stage, the calculation of herd-level PBA, as used in the present study, may be insufficient to demonstrate the actual effects of PED status on the subsequent litter size.
