The food efficiency and intake of food, energy, RYR, and monacolin K of male SD rats fed with RYR for 90 days

Group	Control	20% RYR	40% RYR
Total weight gain(g)	370.6 ± 40.1	275.4 ± 30.9**	293.0 ± 15.9**
Average weight gain(g/day)	4.12 ± 0.45	3.06 ± 0.34**	3.26 ± 0.18**
Average food intake(g/day)	24.97 ± 0.49	21.20 ± 1.29	23.40 ± 2.52
FEa	0.1666 ± 0.0096	0.1417 ± 0.0080	0.1408 ± 0.0064
Average energy intake(kcal/day)	89.98 ± 1.76	78.73 ± 4.80	87.11 ± 9.37
EEb	0.0462 ± 0.0027	0.0382 ± 0.0022	0.0378 ± 0.0017
Red yeast rice intake(g/kg b.w./day)	0	10.82 ± 0.16	22.84 ± 1.49
Monacolin K intake(mg/kg b.w./day)	0	1.310 ± 0.020	2.767 ± 0.180

Values are mean ± SD (n = 5)

^aFE (food efficiency) = Average weight gain (g/day)/Average food intake (g/day)

^bEE (energy efficiency) = Average weight gain (g/day)/Average energy intake (kcal/day)
