The rumen microbiome plays a fundamental role in all ruminant species, it is involved in
health, nutrient utilization, detoxification, and methane emissions. Methane is a greenhouse …

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 …

Feed efficiency is one of the economically important traits for the cattle industry that affects
profit (feed costs) and the environment (production of manure and methane). Due to that …

The global consumption, notably in develo** countries, and production of beef are
increasing continuously, and this requires the industry to improve performance and to …

Methane (CH4) is a greenhouse gas (GHG) produced and released by eructation to the
atmosphere in large volumes by ruminants. Enteric CH4 contributes significantly to global …

In this study, Bos Taurus cattle offered one high concentrate diet (92% concentrate-8%
straw) during two independent trials allowed us to classify 72 animals comprising of two …

Cattle domestication occurred at least twice independently and gave rise to the modern
taurine and indicine cattle breeds. European cattle diversity is generally dominated by …

Antimicrobial growth promoters (AGPs) are commonly used in the livestock industry at
subtherapeutic levels to improve production efficiency, which is achieved mainly through …

This study explored plasma biomarkers and metabolic pathways underlying feed efficiency
measured as residual feed intake (RFI) in Charolais heifers. A total of 48 RFI extreme …

This study investigated whether plasma biomarkers of residual feed intake (RFI), identified
under ad libitum feeding conditions in beef cattle, remained consistent during feed …
