Energy budgets of striped hamsters. A Gross energy intake, GEI; B digestive energy intake, DEI; C gross energy of feces, GEF; D digestibility. Animals were exposed to 21, 10 and 0 °C for 14 days and transferred to a warm temperature at 30 °C on days 15–42. Data are means ± s.e.m. *, significant difference between the groups (P < 0.05), **, P < 0.01, ns, non-significant difference (P > 0.05)
