Eficiência na Produção de Bovinos de Corte de Ciclo Completo no Estado de São Paulo.

It was evaluated the productive efficiency in asset management (pastures, herds and labor) for a sample of twenty-eight full cycle beef production systems, located in the west of the state of São Paulo. For this purpose, the mathematical programming technique known as Data Envelopment Analysis (DEA) was used. An input-product model employed with the representative production variable, the annual gross revenue from the sale of animals and as inputs the assets of the production, pasture area, number of animals in the herd, fixed labor (family and fixed employees) and temporary labor. The result was an average production efficiency for the twenty-eight production systems of 64.9%. Therefore, there is a potential for realizing revenue 45.1% more than that observed, using the same assets, as long as inefficient systems improve their management.
