Resumen
Descripción
The definition of strategies to improve the herd feed efficiency has been shown to be fundamental in the selection of beef cattle, resulting in economic advantages which in turn are necessary to the sustainability of the production system. However, it is also necessary to investigate the impacts of selection for improved feed efficiency in other economic relevant traits such as feedlot performance and carcass traits. Therefore, the aim of this study was to evaluate the relationships between residual feed intake (RFI), profitability, feedlot performance and carcass traits in Brahman cattle. Twenty-four Brahman young bulls from the Uberbrahman Performance Test, carried out between 2011 and 2012, in Uberlandia, MG, Brazil were evaluated.
