Livestock production is an integral component of almost all farming systems in the west Shewa zone. In the highlands and mid-altitudes livestock is mainly used for the supply of draught power and provision of food. Foreign income generated through the export of hides and skin is also an integral part of the country’s economy at the macro level. By-products of livestock in the form of manure are also of economic importance in the mixed crop livestock system for soil fertility improvement. The income generated from selling livestock and livestock products also forms the main income for the farming community in the highlands. In the low lands, livestock is the mainstay of the livelihoods of the pastoralists and agro-pastoralists. Despite its importance, the productivity and economic contribution of the sub-sector is challenged by various technical, socio- economic, political and institutional constraints.
Among the technical constraints, issues related to feed scarcity (quantitative and qualitative dimensions) are the overriding ones, primarily because of biological, economic and environmental issues. Biologically, the process of animal production is virtually a conversion of low quality products with limited alternative uses such as by-products into high quality products such as milk, meat and egg. In this process the quantity and quality of the livestock product is largely a function of the type of feed used and the art of feeding. There are substantial proofs that at the field level both production and reproductive performance are heavily constrained by the quantity and quality of feed. In economic terms, the feed cost usually accounts for 70% of the total cost of livestock production. This influences not only the productivity but also the feasibility of the enterprise. In terms of environmental issues, aspects of making livestock production compatible with resources are basically a function of provision of feed and an appropriate feeding system. Given appropriate management, livestock production is harmonious with the environment.
