The percentage of eaters per litter over time and individual eater classification of piglets based on live home pen observations (A,B) and blue colored rectal swabs (C,D). Litters were either provided with creep feed as a monotonous diet (MO) or four feed items simultaneously as a diverse diet (DD). The feed was presented without (CON) or with substrate (SUB) in one of two feeders. DV, dietary variety; FP, feed presentation. Data are expressed as means ± SEM based on pen averages. 1SUB effect within MO. +, *, **, ***Significant effects at P < 0.10, < 0.05, < 0.01, < 0.001, respectively.
