Body weights (A) and food intake (B) of five male sibling pairs of WT (dashed lines) and αERKO (solid lines) mice from 2–11 months of age. A quadratic function was fit to the data for each group, which indicated significant differences in the linear (body weight) term. Body weights were significantly greater in αERKO compared with WT mice beginning at 3 months of age and subsequently. Despite progressively greater body weight in αERKO mice compared with WT, average food consumption was similar and unchanged over time in the two groups (14.9 ± 0.8 and 14.8 ± 0.8 kcal/day in WT and αERKO, respectively), indicating greater feed efficiency in αERKO mice. SE refers to the overall standard deviation of the error term for each regression analysis.
