1DIAAS-like values were calculated from the digestibility of AAs in cecectomized roosters.
2DIAAS-like values were calculated using the AAFCO (2019) nutrient profiles of AAs for growth and reproduction of cats, and NRC (2006) recommended allowances of AAs for growing kittens.
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, 1.405; histidine, 4.808; isoleucine, 2.258; leucine, 1.783; lysine, 1.858; methionine, 1.545; phenylalanine, 5.603; threonine, 1.964; tryptophan, 5.358; valine, 8.326. SEM values for NRC (2006) recommended allowance data: arginine, 1.512; histidine, 4.006; isoleucine, 1.952; leucine, 1.486; lysine, 2.186; methionine, 1.814; phenylalanine, 4.856; threonine, 1.838; tryptophan, 6.977; valine, 6.934.
a–eWithin a row, means lacking a common superscript differ (P < 0.05); n, 4 roosters per treatment.
