Abstract
- Oxygen consumption (ml X kg0.75 per min) in relation to ambient temperature (Ta) in the raccoon dog (Nyctereutes procyonoides), polecat (Mustela putorius), mink (Mustela vison) and stoat (Mustela erminea) is described by equations y = 14.2 - 0.23x, y = 26.3 - 0.47x, y = 26.9 - 0.33x and y = 39.0 - 1.06x, respectively. Resting metabolic rate (RMR) of blue fox (Alopex lagopus) could be measured only at thermoneutrality. 2. In polecats, calorigenic response to noradrenaline was about 40% above the RMR, while in raccoon dogs it was absent. 3. The cooling constant (per min) of deceased raccoon dogs was similar to that measured for blue fox (0.0008), but considerably higher than that measured for dog (beagle 0.0016) or polecats (0.0023-0.0031).
摘要
- 貉（Nyctereutes procyonoides）、艾鼬（Mustela putorius）、水貂（Mustela vison）和伶鼬（Mustela erminea）的耗氧量（毫升×千克^0.75/分钟）与环境温度（Ta）的关系分别由方程y = 14.2 - 0.23x、y = 26.3 - 0.47x、y = 26.9 - 0.33x和y = 39.0 - 1.06x描述。北极狐（Alopex lagopus）的静息代谢率（RMR）只能在热中性条件下测量。2. 在艾鼬中，对去甲肾上腺素的产热反应比RMR高约40%，而在貉中则没有这种反应。3. 死亡貉的冷却常数（每分钟）与北极狐测量的冷却常数相似（0.0008），但远高于狗（比格犬0.0016）或艾鼬（0.0023 - 0.0031）测量的冷却常数。
