Abstract

There is a need to develop simple ways of quantifying and estimating CH4 production in cattle. Our aim was to evaluate the relationship between CH4 production and milk fatty acid (FA) profile in order to use milk FA profiles to predict CH4 production in dairy cattle. Data from 3 experiments with...

Abstract

We hypothesized that inoculating the rumen of beef cattle with rumen contents of bison and supplementing with exogenous fibrolytic enzymes (FE) would improve ruminal feed digestibility by enhancing microbiome activity in the rumen. The objectives of this study were to evaluate the effects of...

Abstract

Universally applicable empirical equations specific for high- and low-forage diets were developed to improve the prediction of enteric methane production (eCH4) from beef cattle. A database built using treatment means from published beef studies conducted in numerous countries was divided into two...

Abstract

The protocol for the National Inventory of agricultural greenhouse gas emissions in The Netherlands includes a dynamic and mechanistic model of animal digestion and fermentation as an Intergovernmental Panel on Climate Change (IPCC) Tier 3 approach to estimate enteric CH4 emission by dairy cows....

Abstract

Fecal nutrients and apparent total tract digestibility (ATTD) were predicted using near-infrared spectroscopy (NIRS) of feces collected from the pen floor or the rectum of feedlot cattle in 2 studies, and pen floor samples were assessed for their ability to predict NEg, ADG, and G:F. In study 1,...

Abstract

Two experiments were conducted to investigate the effects of adding gallic acid (GA) to ruminant diets on long- and short-term in vitro rumen fermentation and methane (CH4) production, and to test possible interactions between GA and ethanol on fermentation. The first experiment was conducted using ...

Abstract

The objectives of this study were to evaluate the relationship between residual feed intake (RFI; g/d) and enteric methane (CH4) production (g/kg DM) and to compare CH4 and carbon dioxide (CO2) emissions measured using respiration chambers (RC) and the GreenFeed emission monitoring (GEM) system...

Abstract

Wheat is the most common concentrate fed to dairy cows in Australia, but few studies have examined the effects of wheat feeding on enteric methane emissions, and no studies have compared the relative potencies of wheat, corn, and barley for their effects on enteric methane production. In this 35-d...

Abstract

Emissions of CH4 methane from beef cattle grazing pastures characteristic of northern Australia are yet to be reliably quantified. Poor quality pastures and low animal productivity are typically associated with high CH4 emissions/unit animal product. Our study reports two independent methodologies...

Abstract

There are limited data in the literature concerning in vivo effects of dietary fat supplementation on enteric CH4 emissions from lactating dairy cows. The purpose of this experiment was to evaluate four dietary treatments designated as control (CON), brewers grains (BG), hominy meal and...
