Fig. 6. Relationship between the delay in implantation at the start of the second pregnancy in the experimental females and (A) the litter size at the peak of the first lactation (y=0.42x+8.3), (B) the mean pup mass at the end of the first lactation (y=-0.3x+10.3) and (C) the asymptotic daily food intake at the peak of the subsequent (second) lactation (y=-0.6x+25.1).
