Resumen
Descripción
A growing interest in the selection for improved feed efficiency has been observed in the Brazilian breeding industry. However, few information is available on the associations of the feed efficiency measured in individual pens and the performance in the previous growing phase on grazing conditions. Therefore, the aim of this study was to evaluate the relationships between feedlot residual feed intake (RFI) and the performance, the carcass traits and the body traits of Brahman cattle, measured in pastures during the growing phase. Twenty-four Brahman young bulls were used in this study. In the first phase, the cattle (yearlings) were enrolled in a test of performance, carried out from September 2011 to June 2012, in Uberlandia, MG, Brazil.
