Resumo: | This study aimed to verify the influence of supplementation with different associations between organic minerals on performance, carcass characteristics and economic viability for finishing swine. 88 castrated males were divided in four treatments: control with basal diet and supplementation with CrFe, MgSe and CrFeMgSe during the 28 days prior to slaughter. The experimental design was randomized blocks with an experimental plot represented by two animals. The animals supplemented with CrFeMgSe had worse final weight, daily weight gain and consumption throughout the period, with consequent reduction in carcass weight, lower loin depth, loin eye area and amount of lean meat. There was an increase in the effective operational cost of diet with CrFe, MgSe and CrFeMgSe groups, respectively. The use of chromium plus iron and magnesium plus selenium, associated two by two, did not alter the performance parameters and carcass. However, the four minerals association promote a worsening in these characteristics and increase the cost of production. |
