Summary: The investigations comprehend the morphological constitution of raw and tanned leather as well as the enzymatic properties of leather in animals such as: (a) goats and kids proceeding from extensive and intensive breed; (b) buffalos from the Kosovo region. The volume proportion of connective tissue elements within the corium of raw and tanned leather was calculated by means of stereological methods. Physicochemical properties (such as distension and resistance to breaking, percentage of fat, humidity, chromoxide and ashes) were investigated in tanned leather. LDH, SDH, NADPH2 and NADH activity was investigated in raw leather.

Keywords: Raw and tanned leather, morphohistological construction, physicochemical properties, stereological methods, domestic animals.

Research goals: Besides the origin of the raw material, in tanning industry it is very important to know the morphological constitution of leather for it can be influenced by a lot of factors. The aim of the investigation was to offer some methods that might complete the actual knowledge concerning the quality of raw and tanned leather, which was not possible to achieve by the methods still in use in tanning industry. The results of our investigations indicate that, owing to such methods, tanning industry might have the following advanteges: a complete insight of the quality of raw and tanned leather, improvement of the selection of skins and hides in view of their processing, decrease of waste in leather processing.
