Rana esculenta (L.), kept under natural conditions, show almost constant body weights in the annual cycle. Fat body weight, however, has a distinct maximum in October decreasing continuously to a May minimum which is also evident in the fat body index. The triglyceride and protein contents show the same course. Suprisingly high amounts of glycogen are found, which reach a maximum in August.
在自然条件下饲养的食用蛙（林蛙）在一年的周期中体重几乎保持恒定。然而，脂肪体重量在10月有明显的最大值，随后持续下降至5月的最小值，这在脂肪体指数中也很明显。甘油三酯和蛋白质含量呈现相同的变化趋势。令人惊讶的是，发现了大量的糖原，其在8月达到最大值。
