Desempenho e características de carcaça de cabritos em dois sistemas de terminação

Abstract

The aim of this study was to evaluate the performance, quantitative and qualitative characteristics of the carcass, cut yields and the variation of cost and revenue in the production of beef and feedlot goats Saanen, Saanen and 7/8 Boer - 1/8 Saanen finished in semi feedlot, assessing the influence of genetic groups and finishing systems on such characteristics of goats. Significant differences were observed (P<0.05) for the different finishing systems to evaluate the characteristics of commercial income housing; carcass compactness index, not constituents of housing, loin eye area, muscle shear force; fat, moisture and ether extract. For the genetic groups, statistical differences were observed only for loin eye area, greater thickness of fat and ash content. The finishing system has influenced (P<0.05) in performance, where the confined animals showed the best characteristics, the percentage of cuts and, consequently, revenue from the sale thereof. The finishing system has influence on carcass characteristics evaluated in this study, it is possible to conclude that the Saanen can be used for the production of meat when subjected to confinement. When evaluating the quality of housing Saanen crossbred compared to 7/8 Boer - 1/8 Saanen finished in semi confined conditions of this study, we can conclude that there are few differences between the dairy breed Saanen and crossbred Boer for traits, possibly due to production of specialty meat Boer who require an intensive system to demonstrate higher performance. Investment in power gives better weight gains, and hence best proportions of commercial cuts, resulting in a higher income system. Males Saanen can be used for finishing and slaughter, supplementing the income of dairy goat. It is necessary to complete economic analysis to examine the viability of economic systems, since the budget is only a partial indicator of possible better option
