(Extracts from introduction)The objective of this study was to evaluate the technical and economic feasibility of developing a livestock enterprise within the Mogambo irrigation project. Any livestock enterprise would need to fit into the overall strategy of a state farm, but, of necessity, must also relate to the present and proposed developments of the livestock and agricultural sections in the Lower Juba region. The removal of fodder crops from the cropping pattern at Mogambo has meant that emphasis has now to be placed on crop residues and by-products as the principal source of feed.
