The goal of this review was to analyze published data related to mitigation of enteric
methane (CH4) emissions from ruminant animals to document the most effective and …

This document analyzes emission of non-carbon dioxide greenhouse gases, an important
segment of the environmental footprint of animal production. It has been developed by a …

Background Livestock play an important role in carbon cycling through consumption of
biomass and emissions of methane. Recent research suggests that existing bottom-up …

For the past several decades, nutrient requirement systems for beef cattle in North America
have recommended that dietary ME can be calculated as dietary DE× 0.82, but considerable …

Simple Summary Methane produced by enteric fermentation contributes to the emission of
greenhouse gases (GHG) into the atmosphere. Methane is one of the GHG arising from …

The increased use of by-products in finishing diets for cattle leads to diets that contain
greater concentrations of crude protein (CP) and metabolizable protein (MP) than required …

The objectives of this study were to investigate the effects of (1) the addition of nitrate and (2)
an increase in dietary oil on methane (CH4) and hydrogen (H2) emissions from 2 breeds …

Condensed tannins (CT) may decrease greenhouse gas emissions and alter the site of N
excreted by ruminants. We evaluated the effect of top-dressing a steam-flaked corn–based …

In this analysis we used a spatially explicit, simplified bottom-up approach, based on animal
inventories, feed dry matter intake, and feed intake-based emission factors to estimate …

It is necessary to assess the appropriate dietary protein level of the forest musk deer (FMD),
as nutritional needs are unclear. The microbiome in gastrointestinal tracts plays an important …
