1. (A) Maternal body mass, (B) change in body mass and (C) food intake throughout the lactation period in striped hamsters exposed to 23, 30 or 5°C on day 7 of lactation (arrows) and thereafter.
(A) Maternal body mass, (B) change in body mass and (C) food intake throughout the lactation period in striped hamsters exposed to 23, 30 or 5°C on day 7 of lactation (arrows) and thereafter. Change in body mass was significantly lower in the 5°C group than in the 23 and 30°C groups on days 12–19 of lactation. Females lactating at 5°C had significantly higher food intake than other two groups on day 7 and thereafter, except for days 16 and 19. *, significant effects of temperature (P<0.05); **, P<0.01. Values are means ± s.e.m.
