This paper reviews some major aspects of the livestock sector in the Republic of the Sudan. The country has one of the largest livestock populations in Africa. Cattle, sheep, goats, and camels provide milk and meat for local consumption and meat and live animals for export. Ruminants also provide ancillary functions including draught and transport, produce manure and act as a store of wealth. In spite of their importance to the national economy livestock do not receive sufficient attention in government policies and financing. Almost all animals are owned by smallholder farmers or traditional pastoralists. Livestock feed is often in deficit in relation to needs and crop by-products and range vegetation are fibrous and of low nutritional value. Livestock are affected by a multitude of diseases but receive little health care. Access to finance by producers is difficult and credit is limited and expensive if obtainable. Services to the sector are not adequately funded and are generally poorly equipped. Livestock output is low in relation to numbers and to the sector's potential. Some suggestions are made for the improvement of performance that will add value to the sector and contribute to people's livelihoods.
