Characterization of microbial intolerances and ruminal dysbiosis towards different dietary carbohydrate sources using an in vitro model

Journal of Applied Microbiology, Volume 133, Issue 2, Page 458-476, August 2022., 2022
Abstract Aim This study aimed to characterize the critical points for determining the development of dysbiosis associated with feed intolerances and ruminal acidosis. Methods and Results A metabologenomics approach was used to characterize dynamic microbial and metabolomics shifts using the rumen simulation technique (RUSITEC) by feeding native ...

Safety and efficacy of a feed additive consisting of 3‐nitrooxypropanol (Bovaer® 10) for ruminants for milk production and reproduction (DSM Nutritional Products Ltd)

EFSA Journal, Volume 19, Issue 11, November 2021., 2021
Abstract Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the safety and efficacy of Bovaer® 10 as a zootechnical additive for ruminants for milk production and reproduction. Systemic exposure or site of contact toxicity for the active substance 3‐nitrooxypropanol (3‐NOP), for which genotoxicity has ...

In vitro rumen simulations show a reduced disappearance of deoxynivalenol, nivalenol and enniatin B at conditions of rumen acidosis and lower microbial activity [PDF]

, 2020
Ruminants are generally considered to be less susceptible to the effects of mycotoxins than monogastric animals as the rumen microbiota are capable of detoxifying some of these toxins.

Changes in Rumen Microbial Community Composition during Adaption to an In Vitro System and the Impact of Different Forages. [PDF]

PLoS ONE, 2016
This study examined ruminal microbial community composition alterations during initial adaption to and following incubation in a rumen simulation system (Rusitec) using grass or corn silage as substrates.

Effect of dietary supplementation with treated amaranth seeds on fermentation parameters in an artificial rumen

Czech Journal of Animal Science, 2013
The rumen simulating technique (RUSITEC) was used to evaluate the effect of dietary inclusion of amaranth seeds on the rumen fermentation and the concentration of fatty acids (FA) in fermentation fluid. Four fermentation vessels of the RUSITEC were used.

Effect of a glyphosate-containing herbicide on Escherichia coli and Salmonella Ser. Typhimurium in an in vitro rumen simulation system [PDF]

, 2019
Glyphosate (N-(phosphonomethyl)glycine) is the most-used herbicide worldwide. Many studies in the past have shown that residues of the herbicide can be found in many cultivated plants, including those used as livestock feed.

Administration of Streptococcus bovis isolated from sheep rumen digesta on rumen function and physiology as evaluated in a rumen simulation technique system [PDF]

Veterinary World, 2019
Background and Aim: Little information about the stability and changes of sheep ruminal microbiota due to pathogen intervention in the rumen simulation technique (RUSITEC) is available.

Long-Term Mootral Application Impacts Methane Production and the Microbial Community in the Rumen Simulation Technique System

Frontiers in Microbiology, 2021
Methane emissions by ruminants contribute to global warming and result in a loss of dietary energy for the animals. One possibility of reducing methane emissions is by dietary strategies.

Effect of mixtures of legume species on ruminal fermentation, methane, and microbial nitrogen production in batch and continuous culture (RUSITEC) systems

Canadian Journal of Animal Science, 2023
The effect of cicer milkvetch (Astragalus cicer L.) and sainfoin (Onobrychis viciifolia Scop.) on ruminal fermentation, methane production, and microbial nitrogen synthesis was assessed in two experiments.

Comparison of microbial fermentation of high- and low-forage diets in Rusitec, single-flow continuous-culture fermenters and sheep rumen

Animal, 2009
Eight Rusitec and eight single-flow continuous-culture fermenters (SFCCF) were used to compare the ruminal fermentation of two diets composed of alfalfa hay and concentrate in proportions of 80 : 20 (F80) and 20 : 80 (F20).
