Body Weight Gain, Food Intake, and Food Efficiency Ratio of Experimental Rats
| Group | SHAM | OVX | OC | OP |
|---|---|---|---|---|
| Initial weight (g) | 155.8±2.39a | 153.3±1.94a | 155.7±3.07a | 155.5±2.51a |
| Final weight (g) | 325.3±10.44b | 374.4±15.85a | 395.7±10.13a | 385.8±8.75a |
| Weight gain (g) | 169.5±11.03b | 221.2±14.40a | 240.0±7.03a | 230.3±8.48a |
| Food intake (g/week) | 112.5±25.03 | 148.4±28.29 | 114.2±24.11 | 112.0±22.91 |
| FER | 0.149±0.3333a | 0.148±0.0282a | 0.209±0.0440a | 0.204±0.0417a |
All values are mean±SEM (groups SHAM, OC, and OP: n=12; group OVX: n=11). FER=[gain of body weight (g)/week]/[amount of food intake (g)/week].
ab
Means with different letters differ at P<.05 level by ANOVA and Duncan's multiple range test.
Group SHAM, SD rats control diet only; group OVX, ovariectomized rats fed control diet; groups OC and OP, ovariectomized rats fed diets containing 1% royal jelly originated from Cheorwon and Pocheon, respectively, for 12 weeks (4 weeks before OVX and 8 weeks after OVX); FER, food efficiency ratio.
