在一群自由放养的日本猕猴中，进食的模式反映了雌性的等级。高级雌性（HRF）从人造食物中获得约3/4的每日消化能量，从自然来源获得1/4，而低级雌性（LRF）从这两种来源获得的每日消化能量比例大致相等。LRF根据食物供应的季节性变化调整了它们的喂养策略。在冬季，当食物缺乏时，HRF和LRF的膳食组成是不同的。LRF策略包括：（1）寻找新的食物资源，增加50%的食物种类，（2）延长15%的喂食时间，（3）与HRF相比，减少10%的休息和社交活动时间。在夏季，当许多水果和种子，膳食组成相似，LRF策略包括上述第2和第3点。他们还通过减少7%的人工食物摄入量并用天然食物进行补偿来最大限度地减少与HRF的激动剂相互作用。
The pattern of feeding in a free-ranging troop of Japanese macaques reflected female rank. High-ranking females (HRF) obtained about 3/4 of their daily digested energy from artificial foods and 1/4 from natural sources, whereas low-ranking females (LRF) received roughly equal proportions of their daily digested energy from the two sources. LRF adjusted their feeding strategies in relation to seasonal variation of food supply. In winter, when food was scarce, dietary composition was dissimilar for HRF and LRF. The LRF strategy consisted of (1) finding new food resources and increasing the number of food items by 50%, (2) extending feeding time by 15%, while (3) reducing by 10% the time allocated to rest and social activities compared to HRF. In summer, when many fruits and seeds were available, dietary composition was similar, and the LRF strategy consisted of points 2 and 3 mentioned above. They also minimized agonistic interactions with HRF by reducing artificial food intake by 7 % and compensating with natural food.
