Descripción:	With the high demand for lamb and its products on the Brazilian market, there is a need to improve efficiency within the production system. Genetic resources play an important role in this process. This paper discusses the role of these in the various stages of lamb production, looking at environmental adaptations, disease resistance, choice of ram and dam, through conception, lambing, survival, pre and post weaning growth as well as quality issues linked to carcass quality and traceability. We look at the use of both pure and crossbred sheep in rearing systems, as well as the use of molecular markers for parentage identification, reproduction, development and carcass quality. The overall suitability of the genetic resource depends on the breeding/rearing system, markets demands as well as genotype availability. At the end of the day, the most important factors are animal and farmer well-being and sustainability as well as the profit within the enterprise which may change as farm environment and circumstances change.
