Аннотация: Our communication presents results of comparison metabolic rate and respiratory quotient values were determined in birds by two methods: Haldane gas analyzer (closed flow respirometry system) and an open flow respirometry system. In more than 40 species of Passerine birds were measured respiratory quotient (RQ) and basal metabolic rate (BMR). The analysis shows that determinations metabolic rate and RQ obtained by Haldane apparatus and the data measurement RQ obtained by an open flow respirometry systems were identical. The relationship BMR to body weight to the power of 0.72 (BMR/m0,72) and RQ values determination by Haldane gas analyzer and an open flow respirometry system in passerine birds were identical. RQ in winter was lower than in summer. RQ weakly correlates with BMR levels. Our study shows the possibility of using data obtained from previous studies that have been cited by investigators for a long time.
