The Master’s thesis presents the analysis of hair structure of Lithuanian hunted even-toed ungulates. Object of the thesis – back hair of the following hunted even-toed ungulates, located in Lithuania: moose (Alces alces), red deer (Cervus elaphus L.), sika deer (Cervus nippon L.), roe deer (Capreolus capreolus L.), wild boar (Sus scrofa) and European bison (Bison bonasus). Aim of the thesis – to analyse the distinctive morphological features of back hair of the following hunted even-toed ungulates, located in Lithuania: moose (Alces alces), red deer (Cervus elaphus L.), sika deer (Cervus nippon L.), roe deer (Capreolus capreolus L.), wild boar (Sus scrofa) and European bison (Bison bonasus). Methods of the thesis – macroscopic and microscopic examination of back hair. Results of the thesis – following the macroscopic analysis of guard back hair of the hunted even-toed ungulates, located in Lithuania, it was determined that only the hair of wild boar (Sus scrofa L.) might be easily recognized from the general appearance because the hair ends of wild boar are at least once split, i.e., divided into several parts. The shortest is the hair of roe deer, the thinnest – of European bison. Microscopic analysis of hair of the examined Lithuanian hunted even-toed ungulates showed that the most morphological features (scale pattern, distance between scales, etc.) differ. Most similarities were found between macroscopic hair prints of red deer (Cervus elaphus L.) and moose (Alces alces L.). Hair cuticle features of roe deer (Capreolus capreolus L.) differed from other examined animals by fragmental scales, which is especially visible in the hair positions A, B, C. The shaft part D of fur hair of roe deer features an exceptional pattern – mosaic. While analysing the fur hair features, according to seasons, it was determined that the scale distribution in the shaft and guard part of hair only slightly differs during winter and summer seasons, and in most cases, is cross, while the distance between scales varies.
