Figure 5. Time spent on various behaviours and their relationship to body temperature.

(A) shows the total time spent on different behaviours during the behavioural observation in lactation and (B) shows the daily body temperatures associated with different behaviours. Behaviours are categorised as nursing inside nest (closed-diamond), eating (closed-triangle), resting (open-triangle), nursing outside nest (closed-diamond) and general activity (cross). All data are shown as means + S.D. Sample sizes (n) vary from 18 to 26 mice depending on days of lactation (refer to the details in Supplementary Table 1).
