Regression method-derived digestible and metabolizable energy concentrations of partially defatted black soldier fly larvae meal for broiler chickens and pigs

•The objective was to determine the energy value of partially defatted black soldier larvae meal for broiler chickens and pigs.•Ileal digestible energy, metabolizable energy, and nitrogen-corrected metabolizable energy were evaluated in broiler chickens.•Digestible and metabolizable energy were determined in pigs.•Metabolizable energy concentration of partially defatted black soldier fly larvae meal was identical in both species.
