Improvements in feed efficiency of beef cattle have the potential to increase producer
profitability and simultaneously lower the environmental footprint of beef production …

Feed is a major component of variable costs associated with dairy systems and is therefore
an important consideration for breeding objectives. As a result, measures of feed efficiency …

Background Genome wide association studies (GWAS) on residual feed intake (RFI) and its
component traits including daily dry matter intake (DMI), average daily gain (ADG), and …

The cow herd consumes approximately 70% of the annual feed resources. To date, most
genetic evaluations of feed intake in beef cattle have been made in growing animals and …

Background Feed accounts for about 70% of the total cost of poultry meat production.
Residual feed intake (RFI) has become the preferred measure of feed efficiency because it …

The objective of this study was to identify blood metabolites associated with variation
primarily in residual feed intake (RFI) in two populations of beef steers at the University of …

This study evaluated phenotypic (rph) and genetic correlations (rg) between 8 feed
efficiency traits and other traits of economic interest including weight at selection (WS), loin …

This study examined the relationship of residual feed intake (RFI) with digestion, body
composition, carcass traits and visceral organ weights in beef bulls offered a high …

Feeding costs represent one of the highest expenditures in animal production systems.
Breeding efficient animals that express their growth potential while eating less is therefore a …

Genetic and phenotypic parameters for feed efficiency, growth, and carcass traits for
Australian Angus beef cattle were estimated. Growth traits included birth weight (BWT), 200 …
