- This table displays the mixed-effects multi-level logistic regression analysis for Mycoplasma hyopneumoniae seropositivity with sow as a random effect in 4 seropositive groups from 3 farrowing sources. Six groups had more than 20% of pigs test seropositive for M. hyopneumoniae at least once from the end of nursery to the end of finisher by ELISA. However, 2 seropositive groups from 1 farrowing source were excluded from the multivariable analysis as sows and pigs were vaccinated for M. hyopneumoniae
- IAV Influenza A virus
- aCohort One: Pigs were born between May and August; Cohort Two: Pigs were born between October and January
