Many opportunities exist to reduce enteric methane (CH 4) and other greenhouse gas
(GHG) emissions per unit of product from ruminant livestock. Research over the past century …

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 …

Ruminant livestock are important sources of human food and global greenhouse gas
emissions. Feed degradation and methane formation by ruminants rely on metabolic …

Exploring compositional and functional characteristics of the rumen microbiome can improve
the understanding of its role in rumen function and cattle feed efficiency. In this study, we …

The potent greenhouse gas methane (CH4) is produced in the rumens of ruminant animals
from hydrogen produced during microbial degradation of ingested feed. The natural animal …

Molecular microbial ecology techniques are widely used to study the composition of the
rumen microbiota and to increase understanding of the roles they play. Therefore, sampling …

Feed efficiency, as defined by the fraction of feed energy or dry matter captured in products,
has more than doubled for the US dairy industry in the past 100 yr. This increased feed …

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 …

Diversity in the forestomach microbiome is one of the key features of ruminant animals. The
diverse microbial community adapts to a wide array of dietary feedstuffs and management …

Despite substantial advances in milk production efficiency of dairy cattle over the last 50
years, rising feed costs remain a significant threat to producer profitability. There also is a …
