Fig. 8. Maternal body mass on day 0 of lactation (A), increase in maternal body
mass over days 0-13 of lactation (B), maternal body mass on day 13 of
lactation (C) and maternal food intake on day 13 of lactation (D) in mice at
hot (30°C), warm (21°C) and cold (8°C) temperatures. The cold
group was transferred from 21°C to 8°C on day 10 of lactation. Bars
are means + 1 S.D. (N as in text). Different letters above
bars indicate significant differences between the temperatures
(P<0.05), as assessed by ANOVA followed by Tukey pairwise
comparisons.
