Items	Diets		p-Value
	HP	LP
Acetate	39.54 ± 2.62	46.72 ± 2.03	0.046
Propionate	18.87 ± 0.77	16.83 ± 1.27	0.191
Butyrate	8.91 ± 0.54	9.01 ± 1.05	0.937
Isobutyrate	2.16 ± 0.42	2.56 ± 1.74	0.558
Valerate	2.90 ± 0.28	3.30 ± 0.59	0.538
Isovalerate	2.59 ± 0.31	2.45 ± 0.34	0.764
Total SCFA	74.50 ± 3.34	80.90 ± 4.79	0.290

Data are presented as the mean ± standard error of measurement (SEM, n = 10). HP = high protein group; LP = low protein group; Total SCFA, total short-chain fatty acids.
