Enteric methane production from beef cattle contributes to anthropogenic climate change
and represents inefficiency in the ruminant digestive system by allowing energy to escape …

Purpose The beef industry is experiencing pressure to increase the efficiency and
sustainability of forage-based cow-calf production. Dozens of traits affect a cow's ability to be …

The aim of this study was to investigate the effects of feed efficiency classifications on live
animal measurements, circulating IGF-1 and leptin concentrations, and carcass, non …

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 …

Portable accumulation chambers (PAC) enable short-term spot measurements of gaseous
emissions including methane (CH4), carbon dioxide (CO2), and oxygen (O2) consumption …

The objectives of this study were to quantify the effect of post-weaning residual feed intake
(RFI) on subsequent grazed forage intake, methane (CH4), and carbon dioxide (CO2) …

Approximately 70% of the cost of beef production is impacted by dietary intake. Maximizing
production efficiency of beef cattle requires not only genetic selection to maximize feed …

Enteric methane (CH4) emissions are a natural process in ruminants and can result in up to
12% of energy losses. Hence, decreasing enteric CH4 production constitutes an important …

Reduction in greenhouse gas emission from beef production is essential to the survival of
the beef industry from environmental and social-economic perspectives. There are different …

Methane emissions in ruminants are influenced by various factors, including feed type and
rumen microbial population. Mitigation strategies involve nutritional interventions, soil and …
