Seasonal changes in metabolic rates in muskoxen following twenty- four hours of starvation

Timing of seasonal trends in post-prandial energy expenditure (EE) was measured in muskoxen (2 males and 1 female) given a standardized meal followed by a 24-26 h starvation during 10 months over the course of a year. EE was significantly lower in winter than summer. CH4 production (EctM) was revers...
