Two feeding habits of 30 baboons selected equally from five age-sex classes were studied at Mikumi National Park, Tanzania. The finding, gathering, and preparing of sedge corms and of seeds of tamarind fruit were described in detail. Adults obtained these foods faster than younger animals, although even small juveniles and weaned infants were efficient in gathering and preparing them. While gathering sedges or tamarinds, adult males sat in one place longer than others and obtained more food per sitting. Adults ate more pieces of food per minute than juveniles, but adult rates of eating did not differ by sex. The adult rate of food intake was inconsistent with the assumption of different food requirements for males and females of a species with pronounced sexual dimorphism.
在坦桑尼亚的米库米国家公园，对从五个年龄 - 性别类别中平等选取的30只狒狒的两种进食习惯进行了研究。详细描述了莎草球茎和罗望子果实种子的寻找、采集和处理过程。成年狒狒获取这些食物的速度比年幼动物更快，不过即使是小幼崽和断奶的婴儿在采集和处理这些食物方面也很高效。在采集莎草或罗望子时，成年雄性比其他个体在一个地方坐的时间更长，每次采集获得的食物更多。成年狒狒每分钟吃的食物块数比幼年狒狒多，但成年狒狒的进食速度不存在性别差异。成年狒狒的食物摄入量与一个具有明显两性异形的物种中雄性和雌性有不同食物需求这一假设不一致。
