COSTS AND BENEFITS OF BREED UTILIZATION STRATEGIES IN SHEEP

Problems involved in choosing appropriate criteria and procedured for economic analyses of breed and mating system evaluation experiments in sheep are described. Literature is reviewed of experiments in which biological or economic efficiency has been investigated. The range in relative economic merit from the poorest to the best group in an experiment typically is from 100 to 120, with values over 140 not uncommon for the best group in an experiment. Heterosis for exonomic traits per ewe mated has ranged from 2% to 26%. Suggestions are presented for consideration in future studies on the economic ramifications of mating system and breed utilization strategies. Particularly critical is the need to assess accurately the feed costs of individual grazing sheep. Also critically needed are bioeconomic simulation models for each major physical environment and management system for sheep productio
