Feed Efficiency Defined RFI: residual feed intake, RFI is a measure of feed efficiency calculated as the difference between and animal’s actual feed intake and its predicted feed intake, for a given level of production. When RFI is used as a genetic selection tool, the resulting progeny will consume less feed for the same level of production. RFI is independent of growth, body size and other performance traits (Koch et al., 1963), selection for animals with low RFI will lead to reduced feed intake and improved feed efficiency without compromising body size, carcass quality or growth. Lower RFI values are more favorable, cattle with low RFI values are more efficient than cattle with high RFI values. RADG: residual average daily gain, the difference between an animal’s actual weight gain and its predicted gain based on its dry matter intake, body weight maintenance and fat cover. Residual average daily gain puts each animal’s feed intake on the same playing field and looks at differences in average daily gain while RFI puts each animal’s growth and body size on the same playing field and looks at differences in feed intake. When selecting for RADG, cattle with higher values are more desirable than those with lower values, meaning that they had greater ADG for the same amount of feed. DMI: dry matter intake, an animal’s average daily dry matter intake during test. DMI is dependent on the dry matter content of the ration fed during the trial period. Raw F:G: feed to gain ratio, also referred to as feed conversion ratio (FCR). F:G ratio refers to the amount of feed consumed per unit of weight gain on a dry matter basis. A lower ratio is considered more favorable. While selection for F:G (FCR) results in animals that grow faster it is also associated with cattle that have a larger mature size. Adj. F:G: adjusted feed to gain ratio, accounts for differences in animal age and size during test. This currently is the standard of feed conversion efficiency used by the Beef Improvement Federation. This value is the base F:G value multiplied by the contemporary group’s metabolic mid weight divided by the individual’s metabolic mid weight. A lower adjusted F:G ratio is more favorable.
