Abstract
Small ruminants (i.e., sheep and goats) are widespread in the tropics and are important to the subsistence, economic and social livelihoods of a large human population in these areas. The aim of this thesis was to identify the breeding objectives for tropical small ruminants, and to develop appropriate breeding strategies for their improvement. The results indicated that breed substitution and crossbreeding programmes involving temperate breeds are rarely successful due to incompatibility of the genotypes with the farmers' breeding objectives and the production systems. Within-breed selection programmes utilizing indigenous breeds are likely to be more sustainable than breed substitution and crossbreeding. In addition, they help to maintain biodiversity.
