¹DIAAS-like reference values were calculated from the true digestibility of AA in cecectomized roosters.

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

3BSFLA: 0.2% calcium in basal diet + 1.2% CaCl2; BSFLB: 0.2% calcium in basal + 1.2% CaCO3; BSFLC: 0.2% calcium in basal diet + 0.75% CaCO3; BSFLD: 0.2% calcium in basal diet + 0.6% CaCO3 + 0.6% CaCl2.

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