Residual feed intake (RFI) is one of the preferred traits for feed efficiency animal breeding.
However, RFI measurement is expensive and time-consuming and animal ranking may …

Protein metabolism and body composition have been identified as major determinants of
residual feed intake (RFI) in beef cattle fed high-starch fattening diets. This study aimed to …

Residual expressions of enteric emissions favor a more equitable identification of an
animal's methanogenic potential compared with traditional measures of enteric emissions …

In the current economic and environmental context, the selection of livestock phenotypes
combining high feed efficiency (FE) and low greenhouse gas emissions is interesting. This …

Several studies tried to identify digestive determinants of individual variation in feed
efficiency between fattening bulls, because of their importance for breeding and …

Selection for feed efficiency, the ratio of output (eg, milk yield) to feed intake, has traditionally
been limited on commercial dairy farms by the necessity for detailed individual animal intake …

Simple Summary Grass-fed beef is becoming popular; however, there is little research
information on optimising beef cattle performance in such production systems. In grass …

Insufficient dry matter intake (DMI) of pasture by dairy cattle is a major factor limiting growth
and milk production; however, it has been hypothesized that some dairy breeds may be …

Identifying and breeding cattle that are more feed efficient is of great benefit to beef
production. Additionally, it is crucial that genes contributing to feed efficiency are robust …

The objective of this study was to examine the effects of diet energy density on ranking for
dry matter intake (DMI), residual feed intake (RFI), and greenhouse gas emissions. Forty-two …
