Wool is more or equally often a primary purpose for raising sheep breeds compared with mutton and both are more frequently the primary reason than milk. Very few breeds are raised primarily for pelts or fur. Selection objectives and mode of disseminating genetic gain would necessarily vary according to system of production. Besides adaptation and fitness traits, the following are the main ones that are of economic importance: meat production, reproduction rate, wool and milk production and their relations.
