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

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...

Abstract

The objective of this study was to conduct a life-cycle assessment (LCA) of greenhouse gas (GHG) emissions from a typical nongrazing dairy production system in Eastern Canada. Additionally, as dairying generates both milk and meat, this study assessed several methods of allocating emissions between ...

Abstract

It was hypothesized that differences in starch degradability account for observed differences in rumen vaccenic acid (t11-18:1) and milk rumenic acid (RA) concentrations. To test this hypothesis, starch degradability was varied through grain source and by processing. Eight Holstein cows in...

Abstract

An experiment was conducted to determine whether the susceptibility to ruminal acidosis, as defined through differences in days in milk (DIM), milk production level, and ration composition, influences cow feeding, ruminating, and lying behavior and whether these behaviors change during an acute...
