Piglets were provided with creep feed as monotonous diet (MO) or four solid feed items (creep feed, celery, cereal honey loops, and peanuts) simultaneously as diverse diet (DD) before weaning and their pre-weaning diet was presented without (CON) or with substrate (SUB) in one of two feeders. DV, dietary variety; FP, feed presentation. Data are means ± SEM. Within a row superscripts without a common letter differ at P < 0.05. Significant P-values and trends are presented in bold.
