Fig. 6. (A) Daily energy expenditure (DEE) of mouse litters as a function of litter mass. The least-squares relationship explained 45.5% of the variation in DEE and was described by y=1.6x -38.0. (B) Predicted DEE and (C) predicted total energy requirement (TER) for natural litters in late lactation. The relationships between predicted DEE (B) and predicted TER (C) and litter size were described by y=3.77x+38.9 and y=3.15x +74.03 respectively.
