Piglets were provided with creep feed from 2 days of age (CF) or not (NF) before weaning and provided with a weaner diet (CON, n = 64 piglets in 16 pens) or a creep feed supplement on top of their weaner diet (CS, n = 64 piglets in 16 pens) after weaning. PRE, creep feed yes/no pre-weaning; POST, creep feed supplement yes/no post-weaning. Data are means ± SEM based on pen averages.

P < 0.05 are presented in bold.
