Yamashiro, A., Hujii, S. & Yamashiro, T. 2015. The food habit of Sika deer (Cervus nippon) based on rumen contents in West of Tokushima Prefecture, Japan: with special reference to sex and age differences. Shizen Kagaku Kenkyu 29(4): 49-54. (in Japanese with English abstract)
Sika deer (Cervus nippon) rumen contents collected on Tsurugi and Koyadaira in Tokushima Prefecture from February to March in 2015 were examined. The rumen of sika deer contained mainly dicot leaves (49.7%-74.9%), indicating that food habit of sika deer in these areas was a browser. The male adult deer foraged high quality food, because the percentage of conifer leaves and woody fiber in male adult deer was smaller than those of female adult or fawn. This result was not consisted with the food habit of previously examined Northern Honshu deer populations that male adults tend to feed poor nutrient foods. The rumen contents differences among sex and age in our study areas possibly affected by sedentary and wariness of female and fawn deer.
