Abstrakt: This article reports that ninety per cent of pups born to mothers gestating at 36 degree die during the first 24 hour of extra-uterine life. Cross-fostering experiments showed that 50% of these losses were due to maternal failure. Since deaths due to maternal failure were found to be associated with reduced energy or water supplies, it seemed possible that the poor viability of the pups themselves might be due to inadequacy of their energy or water stores at the time of birth. The energy reserves measured were liver glycogen levels and carcase fat content.
