Desmancha de carcaças de bovino: influência no rendimento comercial e nos custos de produção

Abstract

The purposes of this study were to characterize the cutting of beef carcass, to compare suppliers and to develop models of meat dissection and production cost in order to evaluate its effects on the gross profits. The experimental basis was based on 50 samples of Holstein-friesian beef carcasses, 25 from supplier A and the remain 25 from supplier B. The average meat yield was 70,32±1,76%, with the 1st class meat presenting the highest yield (32,83±1,12%). Carcass weight presented itself as a good meat yield predictor. It was found that suppliers did not show a significant effect on the weight of the carcass pieces (P > 0,05). These pieces were grouped in “meat for processing” (MP) and in “vacuum packaged meat” (VPM). The highest meat dissection yield was obtained in MP from supplier B (51,02 %), while the highest cost was observed in VPM from the same supplier (4,24 €/kg). The highest production cost was verified in the VPM of supplier B (4,34 €/kg). It was demonstrated to be more profitable to buy carcasses from supplier A, since the gross profits was higher (0,76 €/kg) then from supplier B (0,64 €/kg). Results obtained with this study allow us to conclude that the implementation of these models in meat industry are of great importance for its economic viability.
