Item	Diets ¹			SEM	P-value
Item	Control	LL	SL	SEM	P-value
Trypsin	139.8^a	104.5^b	103.5^b	11.949	0.0077
Chymotrypsin	0.753^a	0.495^ab	0.337^b	0.121	0.0025
Lipase	94.886	89.77	108.414	5.562	0.0599
Amylase	0.894	0.581	0.706	0.091	0.5563
DPP4	1.561	1.507	1.55	0.031	0.808
HSL	0.415	0.558	0.507	0.028	0.288

SEM = standard error of the mean; DPP4 = dipeptidyl peptidase 4; HSL = hormone-sensitive lipase.

^{a, b} Different letters within a row indicate significant differences at P < 0.05.

Control, a normal protein containing 20% CP; LL, a low ratio of Lys to CP diet containing 17% CP; SL, a standard ratio of Lys to CP diet containing 17% CP; number of observation is 8.
