EFFECT OF POSTURE, FEEDING, LOW TEMPERATURE, AND WIND ON ENERGY EXPENDITURES OF MOOSE CALVES
Abstract
Energy expenditures of two moose calves (Alces alces) were studied during late fall and early winter. Interactions of level of feeding, temperature, and posture were examined using a closed-circuit indirect calorimeter. Interactions of temperature and wind were determined in a wind tunnel using the Douglas-bag technique. Increments in energy expenditure due to feeding were approximately 20% over resting metabolism. The energy cost of maintaining a standing posture was in the order of 35%. As temperature dropped from -20℃ to -30℃, metabolic rate increased 36% while standing, but only 2% while lying. Wind speeds up to 8 m sec-1 increased energy expenditures consistently only at temperatures below -20℃.
