Resumen
Descripción
Since 1996, the Geneplus-Embrapa Program has assisted beef cattle seedstock farmers in decision-making for genetic selection and breeding, through the provision of genetic evaluation of bulls, cows and their products. Amongst the 3.6 million registered animals in the Program, 2.3 million (about 64%) are of the Nellore breed. The economic impact of superior genetic Nellore bulls from the Program was assessed based on their positive Expected Progeny Difference (EPD) on weaning weight, restricted to natural breeding systems. The Method of Economic Surplus was employed, according to which, the net economic benefits account for additional benefits and costs of the introduction of an innovation in comparison to a previous technology. In this study, the net benefits were estimated based on the additional weight of weaned calves resulting from superior Nellore bulls in comparison to the average weight of weaned calves from common commercial bulls, less additional costs.
