Ruminant livestock have an important role to play in improving the nutrition and income of citizens of developing countries. The need for these improvements isoften greatest in the humid tropics. Among the world's ruminants, sheep are second only to cattle intheir production of high quality food protein. Most of the world's one billion sheep are found in temperate or arid/semi-arid tropical environments where a wool fleece isa favorable adaptation. However, an estimated one million sheep are more favorably adapted to the humid tropics because of their hair coat. The small size, high fertility and resulting high offtake of hair sheep suit them well as an effective contributor to the productivity of smallholder systems in the tropics. Unfortunately, relatively little is known about the performance of hair sheep. This lack of knowledge sharply limits effective planning to a: hieve the potential of these genetic resources for the improvement of the welfare of producers and consumers. Objectives The principal objectives of this study were to: 1. Survey hair sheep resources intheir native environment, emphasizing those hair sheep in the Western Hemisphere and Western Africa. 2. Document performance traits, including size, growth, fertility and adaptative traits. The principal objectives of the study were: 1. Survey hair sheep resources under local production conditions; 2.analyze available performance data, including growth, size, fertility and survivability traits; 3. Prublish comprehensive comparison of hair sheep productivity. 3. Publish comprehensive comparison of hair sheep performance intheir native environments.
