aValues are least squares mean of the pen average performance variable analyzed for block and treatment group (Trt) using orthogonal treatment comparisons for the effect of vaccination (Vac), starter diet (Diet) and interaction of vaccination and starter diet (VxD). Initial BW (5.83 ± 0.1 kg) was included as a covariant. Starter diets were fed for the initial 14 d after weaning, and then all pigs were fed common diets from d 14 to 48. There were 13 pens per treatment group. Treatment groups were a single injection at d 3 post-weaning with PCV2/MHYO vaccine (V) or saline (S) and starter diet with 0 % (C) or 6 % spray dried porcine plasma (P)
