The present study was aimed to deepen the knowledge on diet and on feeding preferences of the Italian roe deer. The research was carried on in the Castelporziano Presidential Estate, a protected area of Latium coast. Quadrat method was used to assess plant frequency, whereas diet composition was determined by fecal micro-histological analysis. A total of 143 plant species were identified in the site and 109 of them were found in the feces of the . All over the year, most of the were ingested in low percentages (≤5%) and the most utilized plant species were , , , and . Fagaceae and Rosaceae plant families represented the bulk of the diet and were positively selected. In addition, a positive selection on Fabaceae and Oleaceae families was found in wet season but not in dry one. In both periods the Italian roe deer showed a positive selection for deciduous woody plants and evergreen woody plants, instead avoided wild forbs and wild graminoids. Our results confirmed that this subspecies behaved as a generalist highly selective feeder.
本研究旨在加深对意大利狍饮食及取食偏好的了解。研究在拉齐奥海岸的保护区卡斯泰尔波尔齐亚诺总统庄园进行。采用样方法评估植物频度，而饮食组成则通过粪便显微组织学分析确定。在该地点共鉴定出143种植物，其中109种在狍的粪便中被发现。全年来看，大多数植物的摄入量比例较低（≤5%），最常被利用的植物物种是[此处原文缺失部分植物名称]、[此处原文缺失部分植物名称]、[此处原文缺失部分植物名称]和[此处原文缺失部分植物名称]。壳斗科和蔷薇科植物家族占饮食的大部分，且被积极选择。此外，在雨季发现对豆科和木犀科植物家族有积极选择，而在旱季则没有。在两个时期，意大利狍对落叶木本植物和常绿木本植物均表现出积极选择，而避开野生草本植物和野生禾本科植物。我们的结果证实，该亚种表现为高度选择性的广食性取食者。
