Estimating energy expenditure in mice using an energy balance technique

Objective: To compare, in mice, the accuracy of estimates of energy expenditure (EE) using an energy balance technique (TEE bal : food energy intake and body composition change) vs indirect calorimetry (TEE IC ). Subjects: In 32 male C57BL/6J mice, EE was estimated using an energy balance (caloric i...

Description
Summary:Objective: To compare, in mice, the accuracy of estimates of energy expenditure (EE) using an energy balance technique (TEE bal : food energy intake and body composition change) vs indirect calorimetry (TEE IC ). Subjects: In 32 male C57BL/6J mice, EE was estimated using an energy balance (caloric intake minus change in body energy stores) method over a 37-day period. EE was also measured in the same animals by indirect calorimetry. These measures were compared. Results: The two methods were highly correlated ( r 2 =0.87: TEE bal =1.07*TEE IC –0.22, P
