Characterizing dynamics of PRRSV RNA positivity over time in sows after live virus exposure and associated risk factors based on TOSc samples
PRRSV RNA positivity in sows based on TOSc samples decreased over time and reached low prevalence at 16 weeks post-LVI. PRRSV RNA positivity decreased significantly with the increase in parity. And the production phase effect on PRRSV RNA positivity was more evident at low prevalence compared to high prevalence scenarios.
