Effect of phytosterols on rumen fermentation in vitro

open access: yesGenetics and Molecular Research, 2014
We investigated the effect of phytosterols on rumen fermentation in vitro using gas syringes as incubators. Phytosterols were dissolved in ethyl acetate (8.3%) and added at various concentrations to the common diet in rumen fluid. In vitro gas production (GP) was recorded after 3, 6, 12, 18, and 24 h incubation.

Effects of fermentation products of silage on its intake by cattle [PDF]

open access: yes, 1992
The end-products of silage fermentation have been implicated as factors limiting its intake by ruminant animals, although the contribution of individual chemical components is not clearly understood. A series of experiments were conducted to investigate

Digestion, rumen fermentation and circulating concentrations of insulin, growth hormone and IGF-1 in steers fed diets based on different proportions of maize silage and grass silage [PDF]

open access: yes, 2008
Replacing grass silage with maize silage results in a fundamental change in the ratio of structural to non-structural carbohydrates with commensurate changes in rumen fermentation patterns and nutrient utilisation.

Bio-Fermentation Improved Rumen Fermentation and Decreased Methane Concentration of Rice Straw by Altering the Particle-Attached Microbial Community

open access: yes, 2022
Bio-fermentation technology has been successfully developed for ensiling rice straw; however, its effects on the particle-attached microbial community remains unknown. Therefore, rice straw (RS) and bio-fermented rice straw (BFRS) were used as substrates

Rumen methanogenic archaea and their correlation with enteric methane emission in ruminant animals: A systematic review and meta‐analysis

open access: yesJSFA reports, EarlyView.
Abstract Background Livestock, especially ruminants, are a major source of global methane emissions, primarily produced by methanogenic archaea during enteric fermentation. We performed a systematic review and meta‐analysis to account for factors that could influence the relationship between ruminal methanogenic populations and methane emissions, such ...

A low-cost continuous rumen simulation system for sustainable in vitro fermentation and feed evaluation in ruminant production

open access: yesMethodsX
In vitro simulation of rumen fermentation is critical for improving feed efficiency, assessing dietary interventions, and supporting methane mitigation strategies in ruminant production systems.

Compound‐Specific Stable Isotope Analysis Improves the Association Between Dairy Fatty Acid Biomarkers and Dairy Intake: A Secondary Analysis

open access: yesLipids, EarlyView.
ABSTRACT Increasing evidence suggests that dairy consumption may decrease the risk of chronic diseases. However, this association remains unclear due to methodological limitations. As a part of a secondary analysis, we used compound‐specific stable isotope analysis to increase the accuracy of the dairy FA biomarkers (15:0, 17:0), considering that each ...

In vitro rumen methane output of forb species sampled in spring and summer

open access: yesAgricultural and Food Science, 2012
The chemical composition, in vitro rumen fermentation variables and methane (CH4) output of a range of common forb species sampled in spring and summer, and grass silage (14 treatments in total), were determined in this study.

Development of an Alternative In Vitro Rumen Fermentation Prediction Model

open access: yesAnimals
The aim of this study is to identify an alternative approach for simulating the in vitro fermentation and quantifying the production of rumen methane and rumen acetic acid during the rumen fermentation process with different total mixed rations.

Effect of butorphanol in combination with xylazine during castration of calves: A randomised trial under field conditions

open access: yesVeterinary Record, EarlyView.
Abstract Background In horses, cats and dogs, the opioid butorphanol has been proven effective in management of visceral pain and for peri‐ and postoperative pain relief. The aim of this study was to evaluate physiological responses and indicators of noxious stimuli when adding butorphanol to xylazine for sedation of bull calves during surgical ...
