日本猴进食速度与食叶热量摄入关系的实验

为了了解食叶对日本猴的生物能量效应，在笼中动物上进行了实验。来自Koshima部队的两只猴子在被捕获后不久就被关在笼子里喂树叶。这些猴子接受了测试，以确定它们在多长时间内可以通过只吃树叶或只吃小麦来满足每日的能量需求。12个小时的饲料只吃树叶没有满足猴子的最大日摄入量，而4小时的饲料只吃小麦满足他们的日常能量需求。日摄入量占日能量消耗的比例，叶类为90%，小麦为120%。日本猴子很难只靠吃树叶来满足每天的能量需求。因此，水果（坚果）和叶子的组合必须是他们的能量摄入所必需的。这些事实在研究摄食活动、食物丰富度或家域大小时都要加以考虑。
In order to know the bioenergetic effect of leaf eating in Japanese monkeys experiments were conducted on caged animals. Two monkeys from the Koshima troop were fed with leaves in a cage shortly after their capture. The monkeys were tested to determine in what duration they could fulfill their daily energy requirements by solely leaf eating or by solely wheat eating. Twelve hours of feeding solely on leaves did not fulfill the monkeys' maximum daily intake, whereas 4 hr of feeding solely on wheat satisfied their daily energy requirements. The ratio of the daily intake to the daily energy consumption was 90% for leaf eating and 120% for wheat eating. It is difficult for Japanese monkeys to fulfill their daily energy requirements by leaf eating only. Thus, the combination of fruits (nuts) and leaves must be necessary for their energy intake. These facts are to be considered in the studies of feeding activity, food abundance, or the home range size.
