aValues are least squares mean of percentage mortality, individual pig body weight (BW) and carcass variable by day or period of experiment analyzed for the effects of sex (S), treatment group (Trt), and interaction of Trt and sex (TxS), using orthogonal treatment comparisons for the main 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 145. Treatment factors 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)
bDay or period of experiment
cNumber of carcasses classified at abattoir differed from number of pigs finished due to culling or lost carcass identification
dLive BW of pigs at d 145 that subsequently had carcasses classified on d 159
