Avaliação econômica de sistemas de produção de ovinos de corte na região Nordeste.

Abstract

The objective was to evaluate the economic viability of three sheep production objectives, differentiated by technological levels of exploration. Environmental and technical assumptions are assumed for the structuring of technological matrices. The Technological Matrix 1 considers a total of 176 animals, distributed in 100 hectares of native Caatinga pasture, with forage and mineral supplementation. For this system, nutritional, sanitary and reproductive management with more extensive characteristics is considered. For Technological Matrix 2, the initial module of 315 animals is assumed, at a moderate technological level, distributed in native Caatinga pasture enriched with Buffel grass (Cenchrus ciliaris) and rearing and finishing the lambs (as) on pasture in this cultivar. The Technological Matrix 3 has an initial herd of 598 animals, with lambs (as) finished in a confinement system, and allocation of the other categories of animals in Buffel grass pasture (Cenchrus ciliaris), considering more desirable zootechnical indices. The operational costs of technological matrices 1, 2 and 3 were calculated for the analysis of performance measures in determining a possible stable system. The technological matrix 1 obtained values of R$ 19.666,25, R$ 36.401,24 and R$ 37.654,79 for Effective Operating Cost (COE), Total Operating Cost (TOC) and Total Production Cost (CTP). In technological matrix 2, it found values of R$ 44.947,75 for COE, R$ 74.548,19 for COT and R$ 77.078,39 for CTP. In technological system 3, it obtained values of R$ 118.511,00 (COE), R$ 172.482,64 (COT) and R$ 176.152,84 (CTP). The values of fixed assets of the production systems were calculated, based on the cost of machinery and equipment, improvements and animals, estimating R$ 50.785,00 for technological matrix 1, R$ 151.385,00 of fixed assets for technological matrix 2 and R$ 250.840.00 for the technological matrix 3. Through the calculations obtained from the Gross Revenue (RB), Gross Margin (MB), Net Margin (ML), profitability and cost benefit ratio (BC), return evaluation values were observed and profitability in the production costs of technological matrix 2, representing R$ 170.563,39 for RB, R$ 52.052,39 for MB, R$ 1.919,25 for ML, R$ -5.589,45 for profitability and 0,97 for the index BC.
