... expenditure, litter size and pup masses over the course of lactation. Our results show that, in line with the concept of heat dissipation limitation, female golden hamsters had the largest energy intake under the coldest conditions and a significantly lower intake at 30°C (partial for influence of ambient...

... were adjusted to 12 (±1) pups. Females in the experimental group had higher energy intake ( F 1,14 =15.8, P =0.0014) and higher assimilated energy ( F 1,13 =10.7, P =0.006), and provided their pups with more milk ( F 1,13 =6.65, P =0.03), consistent with the heat dissipation limit theory. Yet, despite...

... for Swiss mice are inconsistent with this hypothesis. To examine the role of limits to heat dissipation on SusEI, the body temperature, thermal conductance and lactation performance were measured in dorsally shaved Swiss mice. Shaving reduces external insulation and the heat dissipation limitation...
