对1988年夏~ 1989年春在日本北部Goyo山采集的58头梅花鹿瘤胃内容物的植物和化学成分进行了分析。矮竹（Sasa nipponica）在夏季（35.0%）和冬季（61.4%）中占重要地位，秋季降至5.6%，被腐叶取代，冬季降至28.0%，被木本植物的枯叶、树枝和树皮取代。洗涤馏分的粗蛋白质含量比粗馏分低20-25%。夏季最高（16.2%），冬季最低（8.6%）。夏季和秋季食物中蛋白质含量高，主要归因于牧草和浏览叶。梅花鹿食物中蛋白质含量的季节性波动大于苏格兰兰姆地区的马鹿，小于美国怀俄明州黄石国家公园的瓦皮蒂鹿。在气候上，高yo山的冬季严酷程度介于这两个地方之间，这似乎解释了蛋白质水平的季节性波动。粗纤维在洗涤馏分中占33%，且不随季节变化。
Botanical and chemical compositions of the rumen contents of 58 Sika deer on Mt Goyo, northern Japan, collected from summer of 1988 to spring of 1989, were analyzed.Sasa nipponica, a dwarf bamboo, was important in summer (35.0%) and winter (61.4%), but it decreased to 5.6% and was replaced by browse leaves in fall, and to 28.0% and was replaced by dead leaves, twigs and bark of woody plants in winter. Crude protein was 20–25% lower in the washed fraction than in the gross fraction. It was highest (16.2%) in summer and lowest (8.6%) in winter. High protein content in summer and fall foods was attributed to forb and browse leaves. Seasonal fluctuation in protein content in the foods of these Sika deer was greater than red deer on Rhum, Scotland and smaller than wapiti in Yellowstone National Park, Wyoming, USA. Climatically, winter severity of Mt Goyo is intermediate between the two localities, which seems to explain the seasonal fluctuation of the protein level. Crude fiber wasca33% in the ‘washed’ fraction, and did not change seasonally.
