G.  aDEA performance evaluation of livestock systems in Brazil.  c2012  a15 p.  aThis study evaluated the performance of 21 beef cattle modal production systems in 21 municipalities of 7 Brazilian states. The cow-calf phase, which is the activity that supports the entire livestock production chain, was evaluated. The data envelopment analysis (DEA) model for variable returns to scale with weights restrictions was applied. The objective was to measure the performance of the rancher's decision regarding the composition of the production system. From the 21 systems evaluated, 4 were DEA efficient. Most of the evaluated systems were operating under increasing teturns to scale.  abeef cattle  alivestock  aPerformance  aCow-calf  aMeasure  aProduction  aProduction system1 aABREU, U. G.
