Results are reported from studies conducted on the feeding of the red deer in certain regions of the Central Balkan mountain. In two State game reserves, situated in. North and South Bulgaria, respectively, a total of 52 female red deers were shot and botanical analysis is made of their stomach content. The importance of the different vegetable species or groups of foods is determined with the aid of the rate of significance, which combines the percentages of the weight of the nutritive components and the number of cases in which these components are encountered. In the region of the objects studied of basic importance for feeding the red deer at the beginning of the winter season are three types or groups of food with the respective percentage of significance as follows: Rubus sp. .sbd. 68.07 and 60.53; Prunus laurocerasus .sbd. 27.80 and 18.37; and Herba sp. .sbd. 2.62 and 11.28. Besides, in the region of South Bulgaria in the feeding of the red deer participates also the woodrush (Luzula sp.) with percentage of significance 6.60, while in North Bulgaria this percentage is negligible .sbd. only 0.59. All remaining types of food with percentage of significance from 2.01 to 0.01 may be refered to the secondary or casual foods. The percentage of significance of the coniferous species is 0.68 for North Bulgaria and 2.01 .sbd. for South Bulgaria. These insignificant rates show that at the beginning of the winter period at rich food base of the main species the coniferous species are casual components in the food of the red deer.
