Post-weaning average daily gain (ADG), final body weight, dry matter intake (DMI) of pellets, BSFL, and both pellets and BSFL combined (total), and days with (watery) diarrhea of piglets that had access to either only creep feed (Pre-C) or creep feed and live black soldier fly larvae (Pre-L) pre-weaning, and consequently had access to no larvae (Post-C) or had access to live black soldier fly larvae (Post-L) post-weaning. P-values of the effect of pre-weaning treatment (Pre), post-weaning treatment (Post) and their interaction (Pre*Post) are presented, and significant effects (p < 0.05) are indicated in bold and trends (p < 0.1) are indicated in italic. Data are presented as pen means ± SEM.
