Ruminant production systems face significant challenges currently, driven by heightened
awareness of their negative environmental impact and the rapidly rising global population …

Background Feed efficiency is jointly determined by productivity and feed requirements, both
of which are economically relevant traits in beef cattle production systems. The objective of …

Background Feed intake plays an important economic role in beef cattle, and is related with
feed efficiency, weight gain and carcass traits. However, the phenotypes collected for dry …

Five hundred and seventy-five Nellore steers were evaluated for residual feed intake and
residual feed intake and gain and their relationships between carcass, non-carcass and …

This study was conducted to evaluate associations of performance traits, feed efficiency, and
blood variables with residual feed intake (RFI) in growing Nellore cattle. A total of 118 …

The objective of this study was to evaluate residual feed intake (RFI), residual intake and
body weight gain (RIG) and their relationship with other traits of efficiency, performance, and …

Feed intake and average daily gain (ADG) in Nellore cattle were determined to calculate
residual feed intake in two performance tests: first during the growth phase (RFIgrowth) and …

This study estimated genetic parameters and (co) variance components for dry matter intake
(DMI), average daily gain (ADG), feed conversion rate (FCR), residual feed intake (RFI) …

The objective of the present study was to assess the relationship between residual feed
intake (RFI) evaluated in a feedlot-performance test and on pasture, and to determine the …

Empty body and carcass chemical compositions, expressed as content of water, ether
extract, protein, minerals, and energy, were evaluated in Nellore bulls with different residual …
