Abstract

Ethiopia has the largest livestock inventories in Africa including about 40.7 million cattle, 25.5 millions sheep and 23.4 million goats [1]. Its resource of cattle, sheep, and goats ranks 1st, 3rd and 2nd respectively in Africa [2]. The development of leather industry requires great quality of raw materials of various origins, the principal source of which is livestock industry. Although the livestock production and tanning industry of the world are increasing in number, the source of the material for the tanning industry is limited both in quantity and quality.
