ADFI (g/day)	309.46 ± 7.99¹⁾	295.23 ± 11.62	284.97 ± 19.67	0.47
CP intake (g/day, DM)	46.48 ± 1.20^c	62.50 ± 2.46^b	78.65 ± 5.43^a	< 0.001
MEI (kcal/day)	725.50 ± 18.74	703.46 ± 27.70	690.87 ± 47.68	0.77

Adult beagle dogs (n = 8/group) were fed experimental diets for 10 days.
All experimental diets had chicken powder as the protein source, and each experimental diet was formulated to contain 20%, 30%, and 40% CP.
Values are expressed as the mean ± standard error of the mean (SEM).
Data without the same superscript numbers in the same row differ significantly (p < 0.05).
ME, metabolizable energy; ADFI, average daily food intake; MEI, metabolic energy intake; mBW, metabolic body weight.
