Piglets were provided with one solid feed item as monotonous diet (MO) or four solid feed items as diverse diet (DD) before weaning and their pre-weaning diet was presented without substrate (CON) or with substrate (SUB). DV, dietary variety; FP, feed presentation. Data are means ± SEM based on pen averages. Within a row superscripts without a common letter differ at P < 0.05. Significant P-values and trends are presented in bold.

¹No significant differences were observed using post-hoc pairwise comparisons of least squares means.
