Impact of zearalenone on quorum sensing signaling molecules and its association with the suppression of ruminal microbial fermentation in a RUSITEC system. [PDF]

J Anim Sci Biotechnol
Zearalenone (ZEN), a common mycotoxin in ruminant diets, could disturb the rumen ecosystem and impair rumen fermentation. Noticeably, ZEN has been shown to reduce the relative abundances of specific bacterial taxa that potentially possess quorum sensing (

Effect of commercial slow-release urea product on in vitro rumen fermentation and ruminal microbial community using RUSITEC technique. [PDF]

J Anim Sci Biotechnol, 2022
The objectives of this study were to determine the effect of commercial slow-release urea (SRU) on in vitro fermentation characteristics, nutrient digestibility, gas production, microbial protein synthesis and bacterial community using a rumen simulation

A shift towards succinate‐producing Prevotella in the ruminal microbiome challenged with monensin

PROTEOMICS, Volume 23, Issue 21-22, November 2023., 2023
Abstract The time‐resolved impact of monensin on the active rumen microbiome was studied in a rumen‐simulating technique (Rusitec) with metaproteomic and metabolomic approaches. Monensin treatment caused a decreased fibre degradation potential that was observed by the reduced abundance of proteins assigned to fibrolytic bacteria and glycoside ...

The application of rumen simulation technique (RUSITEC) for studying dynamics of the bacterial community and metabolome in rumen fluid and the effects of a challenge with Clostridium perfringens. [PDF]

PLoS ONE, 2018
The rumen simulation technique (RUSITEC) is a well-established semicontinuous in vitro model for investigating ruminal fermentation; however, information on the stability of the ruminal bacterial microbiota and metabolome in the RUSITEC system is rarely ...

In vitro aflatoxins recovery after changing buffer or protozoa concentrations in the rumen fermentation fluid

Journal of Animal Physiology and Animal Nutrition, Volume 107, Issue 6, Page 1311-1319, November 2023., 2023
Abstract This study simulates in vitro the effects of (i) rumen acidity and (ii) change in rumen protozoa numbers on the recovery of aflatoxins (AFs). Two 24‐h fermentation experiments were carried out using the same batch in vitro fermentation systems and substrate (dried corn meal) containing 11.42, 2.42, 7.65 and 1.70 µg/kg of AFB1, AFB2, AFG1 and ...

Can perfluoroalkyl acids biodegrade in the rumen simulation technique (RUSITEC)? [PDF]

Environmental Sciences Europe, 2015
The behaviour of perfluoroalkyl acids (PFAAs) in tissues of ruminants has been shown to differ from that of monogastrics (J Agric Food Chem 61(12):2903-2912 doi:10.1021/jf304680j, 2013; J Agric Food Chem 62(28):6861-6870, 2014). This may be a consequence of the complex microbial ecosystem in the rumen. To evaluate this hypothesis, the recovery of PFAAs

A pilot investigation on the effect of induced saliva flow on digestive parameters in sheep, and a comparison with cattle

Journal of Animal Physiology and Animal Nutrition, Volume 107, Issue 5, Page 1176-1186, September 2023., 2023
Abstract Sheep with a relatively low methane yield were observed to have shorter fluid and particle mean retention times (MRT). Because the application of pilocarpine, a saliva stimulant, was successful in reducing retention times in ruminants in previous studies, we applied this substance to sheep, expecting a reduction in MRT and methane yield. Three

Safety and efficacy of a feed additive consisting of an extract of condensed tannins from Schinopsis balansae Engl. and Schinopsis lorentzii (Griseb.) Engl. (red quebracho extract) for use in all animal species (FEFANA asbl)

EFSA Journal, Volume 20, Issue 12, December 2022., 2022
Abstract Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the safety and efficacy of an extract of condensed tannins from Schinopsis balansae Engl. and Schinopsis lorentzii (Griseb.) Engl. (red quebracho extract) when used as a sensory additive in feed and water for drinking for all animal species. The

Effect of brown and green seaweeds on diet digestibility, ruminal fermentation patterns and enteric methane emissions using the rumen simulation technique

Frontiers in Animal Science, 2022
Inclusion of the red seaweed Asparagopsis taxiformis as a feed additive, has led to significant reductions in methane (CH4) production from ruminants.

Amaranthus grain as a new ingredient in diets for dairy cows: productive, qualitative, and in vitro fermentation traits

Journal of the Science of Food and Agriculture, Volume 102, Issue 10, Page 4121-4130, 15 August 2022., 2022
Abstract BACKGROUND In recent decades, grain amaranths have attracted attention due to their valuable combination of nutritional traits, with higher protein and oil content than conventional cereals. Before they can be proposed as an unconventional ingredient in animal feed, many aspects still need to be investigated from field production to nutritive ...
