Relationship between (A) the mass of the litter at birth and the maternal resting metabolic rate at peak lactation (RMRL) (y=3.16x+5.7), (B) the asymptotic food intake and maternal RMRL (y=2.55x+13.4) and (C) the mean pup mass and maternal RMRL (y=1.2x+12.5) for females raising unmanipulated litters.
