MYHO ELISA results by treatment and day of experiment. Values are least squares means of treatment group by day of experiment for serum inhibition titer (Inh%, bars, left vertical scale) and percentage positive samples (%+, lines, right vertical scale) against MHYO (26 samples per treatment by day). Inhibition percentage >65 was considered positive. Treatment groups were vaccinated (V) or saline (S) injected pigs on d 3 after weaning that were fed starter diets with (P) or without (C) spray-dried porcine plasma for the initial 14 d post-weaning. One pig per pen was challenged with PCV2 inoculum on d 63 after weaning. Data was analyzed for the effects of sex, treatment group and interaction of treatment group and sex using orthogonal treatment comparisons for the main effects of vaccination (1 VC + 2 VP vs 3 SC + 4 SP), starter diet (1 VC + 3 SC vs 2 VP + 4 SP) and interaction of vaccination and starter diet (1 VC + 4 SP vs 2 VP + 3 SC). *Main effect of vaccination for day 35, 63, and 78 of the experiment (P <0.05) for both inhibition titer and percentage of positive samples
