This table displays the mixed-effects multi-level logistic regression analysis for porcine reproductive and respiratory syndrome virus (PRRSV) seropositivity with sow as a random effect in 2 seropositive groups from 2 different farrowing sources that had more than 20% of pigs test seropositive to PRRSV by ELISA
IAV influenza A virus
aHC high complexity diet; LC low complexity diet
