¹DIAAS-like values were calculated from the digestibility of AAs in cecectomized roosters.

²DIAAS-like values were calculated using the AAFCO (2019) nutrient profiles and NRC (2006) recommended allowances of AAs for adult cats at maintenance.

³BSFL0, day 0, day of hatch of black soldier fly larvae; BSFL11, day 11 of age of black soldier fly larvae; BSFL14, day 14 of age of black soldier fly larvae; BSFL18, day 18 of age of black soldier fly larvae; BSFL23, day 23 of age of black soldier fly larvae; BSFL29, day 29 of age of black soldier fly larvae. SEM values for AAFCO (2019) nutrient profile data: arginine, 1.452; histidine, 4.436; isoleucine, 2.108; leucine, 1.595; lysine, 2.328; methionine, 4.150; phenylalanine, 6.312; threonine, 1.702; tryptophan, 7.256; valine, 7.449. SEM values for NRC (2006) recommended allowance data: arginine, 1.508; histidine, 4.068; isoleucine, 1.961; leucine, 1.492; lysine, 4.371; methionine, 3.756; phenylalanine, 4.856; threonine, 1.838; tryptophan, 6.870; valine, 6.966.

^a–eWithin a row, means lacking a common superscript differ (P < 0.05); n, 4 roosters per treatment.
