Diferentes sistemas de produção de bovinos de corte em pastagem, confinamento convencional e confinamento a partir do desmame sobre desempenho animal, características de carcaça e custo de produção

The beef cattle production system has shown significant evolution in the quantity and quality of meat, turning Brazil into its second largest producer and first exporter in the world. In addition to production, Brazil is experiencing significant advances in meat quality with the aim of reaching more demanding markets, both internally and externally. This review aims to update the knowledge on beef carcass production and evaluation systems after the beginning of the new millennium. The new knowledge discussed regards the evolution of production systems, starting from a pasture system, migrating to a system herein called conventional, and ending with a more intensive system that is the finishing of uncastrated cattle in feed-lots with rations of high energy and protein density. In addition to the concepts on breeding, rearing and fattening systems, the evolutions observed in slaughter and carcass dressing will also be presented.
