Increasing food production for the growing human population off a constraining land base
will require greater efficiency of production. Genetic improvement of feed efficiency in cattle …

Animal's feed efficiency in growing cattle (ie the animal ability to reach a market or adult BW
with the least amount of feed intake), is a key factor in the beef cattle industry. Feeding …

Residual feed intake (RFI) is the difference between the actual and expected feed intake of
an animal based on its BW and growth rate over a specified period. The biological …

Feed efficiency is a highly important economic trait in sheep production and has a significant
impact on the economic benefits of sheep farming. Microbial fermentation of the rumen has a …

Globally, there are approximately one billion beef cattle, and compared with poultry and
swine, beef cattle have the poorest conversion efficiency of feed to meat. However, these …

Methane gas from livestock production activities is a significant source of greenhouse gas
(GHG) emissions which have been shown to influence climate change. New technologies …

Climate represents one of the main limiting factors of production efficiency. Thermal stress
events can cause reduced performance, morbidity, and mortality, resulting in significant …

Cattle with high feed efficiencies (designated “efficient”) produce less methane gas than
those with low feed efficiencies (designated “inefficient”); however, the role of the methane …

Linkage of rumen microbial structure to host phenotypical traits may enhance the
understanding of host–microbial interactions in livestock species. This study used culture …

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 …
