: 2日龄和7日龄大鼠在“禁食”(3 h 30 min)和“再喂”(75 min)时,在热中性温度35℃下测量气体交换。各幼崽复饲后CO2产量、耗氧量和呼吸商均显著升高。两种基因型在第2天的气体交换增加百分比相似。在第7天,Fa/ Fa的增加百分比显著高于Fa/ Fa幼崽。这证明了7天大的幼犬在饮食诱导的产热方面存在缺陷。然而,由于这种缺陷(不像非寒颤产热)在2日龄的幼崽中不存在,因此可以得出结论,这可能不是主要因素,而是7日龄的fa/fa幼崽中已经存在的肥胖的结果。
: Gas exchanges were measured at the thermoneutral temperature of 35 degrees C on "fasted" (3 h 30 min) and then "refed" (75 min) fa/fa and Fa/fa rats aged 2 and 7 days. The CO2 production, O2 consumption and respiratory quotient increased significantly after refeeding in all pups. The percentage of increase in the gas exchanges was similar in both genotypes at 2 days. At 7 days, the percentage of increase was significantly higher in Fa/fa than in fa/fa pups. This demonstrated a defect in diet-induced thermogenesis in 7-day old pups. However, since this defect (unlike non-shivering thermogenesis) was absent in 2-day old pups, it is concluded that it is probably not a primary factor but rather a consequence of the obesity already present in fa/fa pups at 7 days of age.
