The government strategically planned for importing raw skins from neighboring countries and also for effective utilization of available raw material resources in the country. The meat of Wanke sheep is in high demand in international markets, but the skin commands low price not only due to low availability but also less demand by tanners due to natural problems associated with the skin. Hence, tanners treat the skin as a reject. The problems of Wanke skin include high natural fat deposition, thin substance and low strength. Usually, leathers made out of Wanke skins have low selections compared to Ethiopian sheep skins and are mainly utilized for making lining leather. In this work, efforts have been made to develop a process technology for making high value leathers with improved properties from Wanke sheepskin.

Studies on ethiopian sheep skins as an opportunity for value addition part I : histological, microscopic and chemical characterization of abyssinian and wanke sheepskins / H. Mohammed in JOURNAL OF THE AMERICAN LEATHER CHEMISTS ASSOCIATION (JALCA), Vol. CIX, N° 3 (03/2014)

Ethiopian tanners face a shortage of raw material input for production of leather. The government strategically planned for importing raw skins from neighboring countries and also for effective utilization of available raw material resources in the country. About fourteen sheep breeds are recognized in Ethiopia. Among the available resources, Wanke sheepskins, indigenous to lowland of Ogaden area of Somali Region take prime position based on their availability. Meat of Wanke sheep is in high demand in international market, but the skin commands low price not only due to availability but also less demanded by tanners due to natural problems associated with the skin. In this paper the histological, chemical and physical characteristics of Wanke sheepskins have been analyzed using various tools and techniques. This characteristic understanding of the Wanke sheepskins will enable the development of process strategy to produce Wanke leathers with improved properties.
