Basal metabolic rate (BMR) provides a widely accepted benchmark of metabolic
expenditure for endotherms under laboratory and natural conditions. While most studies …

Residual feed intake (RFI) is a measure of feed efficiency that is independent of level of
production, such as size and growth rate in beef cattle, and thus is a useful new trait for …

Experiments on Angus steer progeny following a single generation of divergent selection for
residual feed intake suggest that there are many physiological mechanisms contributing to …

There is a growing body of evidence that there is genetic variation in beef cattle feed intake
relative to their liveweight and weight gain. Difference in feed intake, above and below that …

Feed intake (FI), weight gain (WG), metabolic weight (MW), feed conversion ratio (FCR),
residual feed intake calculated by regression (RFI) and feeding standards formulae (RFIS) …

The question of the selection forces which initiated the evolution of endothermy in birds and
mammals is one of the most intriguing in the evolutionary physiology of vertebrates. Many …

We investigated the relationship between resting metabolic rate (RMR) and various
morphological parameters in non-breeding mice, selected for high and low food intake …

The expected reduction in methane emissions from the Australian beef herd resulting from
using bulls identified as being more feed efficient as a result of having a lower residual feed …

The objectives of this study were to determine if residual feed intake (RFI) classification of
beef heifers affected efficiency of forage utilization, body composition, feeding behavior …

Residual feed intake (RFI), defined as the difference between observed and predicted feed
intakes, has been explored as a relevant selection criterion to improve feed efficiency in …
