ADFI Average daily feed intake, SEM Standard error of the mean, C Control, BSF Black soldier fly, YM Yellow mealworm, P1 The hour before insect larva provision, P2 The hour during insect larva provision, P3 The hour after insect larva provision
1Three dietary treatments: C: control, commercial feed; BSF: commercial feed + 5% live BSF larvae; YM: commercial feed + 5% live YM larvae
a–cMeans with lowercase superscript letters denote significant differences among treatments (P < 0.05)
A–CMeans with uppercase superscript letters denote significant differences among periods (P < 0.05)
α,βMeans with Greek alphabet superscript letters denote significant differences between week intervals (P < 0.05)
