“…RFI can be defined as the difference between the observed feed intake recorded over a period and the expected feed intake based on the animal's growth rate and maintenance requirement, that is, measured as dry matter intake (DMI) corrected for liveweight and growth rate (Koch et al, 1963). RFI is the most preferred indicator of feed efficiency in beef cattle as the selection to improve growth (Berry & Crowley, 2012, 2013; Brunes, Baldi, Lopes, Lobo, et al, 2021; Brunes, Baldi, Lopes, Narciso, et al, 2021; Crowley et al, 2010; Herd & Arthur, 2009), reproductive (Berry & Crowley, 2013), and carcass‐related traits (Berry & Crowley, 2013; Brunes, Baldi, Lopes, Lobo, et al, 2021; Brunes, Baldi, Lopes, Narciso, et al, 2021; Herd & Arthur, 2009; Torres‐Vázquez et al, 2018) would not affect RFI.…”
