Gastro-intestinal tract segment length, segment weight, digesta weight, digesta pH and marker passage through the everted intestinal sacs of piglets that had no access to larvae (CC) or pigs that had access to live black soldier fly larvae during the pre- and post-weaning period (LL). Significant effects (p < 0.05) are indicated in bold and trends (p < 0.1) are indicated in italic. Data are presented as pig means ± SEM.
