Effect of microbial isolates on microbial yield estimation in RUSITEC system

BSAP Occasional Publication, 1998
The estimation of rumen microbial protein synthesis is one of the main points in the nitrogen (N)-rationing systems for ruminants, as microbial protein provides proportionately 0.4 to 0.9 of amino acids entering the small intestine in ruminants receiving conventional diets (Russell et al., 1992).

Eremophila glabra reduces methane production and methanogen populations when fermented in a Rusitec

Anaerobe, 2014
Eremophila glabra Juss. (Scrophulariaceae), a native Australian shrub, has been demonstrated to have low methanogenic potential in a batch in vitro fermentation system. The present study aimed to test longer-term effects of E. glabra on rumen fermentation characteristics, particularly methane production and the methanogen population, when included as a

Degradation of condensed tannins by rumen microbes exposed to quebracho tannins (QT) in rumen simulation technique (RUSITEC) and effects of QT on fermentative processes in the RUSITEC

Journal of the Science of Food and Agriculture, 1995
AbstractIn an earlier study it was observed that the rumen microbes from cattle which had never consumed tannin‐containing diets do not have enzymes for degrading condensed tannins. In this study, rumen microbes were exposed to small amounts of quebracho tannins for 8 days using a rumen simulation technique (RUSITEC).

Use of the rumen simulation technique (rusitec) to provide micro-organisms for assessing forage rate-of-fermentationin vitro:effect of solid food input to rusitec

Proceedings of the British Society of Animal Production (1972), 1994
In a previous experiment (Barbi, Owen & Theodorou, 1993) effluent fluid from thein vitrorumen simulation technique (RUSITEC - Czerkawski & Breckenridge, 1977) was used as a source of inoculum when fermenting forage in the Pressure Transducer Technique (PTT - Theodorou, Williams, Brooks, Dhanoa, McAllan & Gill, 1993).

PSXII-24 Effects of a phytogenic mixture with or without direct-fed microbials on ruminal fermentation in an artificial rumen system (Rusitec).

Journal of Animal Science
Naturally occurring plant secondary compounds (NOPSC) and direct-fed microbials (DFM) are potential alternatives to in-feed antibiotics. However, information about the efficacy of combinations of NOPSC and DFM in modulating rumen fermentation is ...

Bioactive polysaccharides and oligosaccharides as possible feed additives to manipulate rumen fermentation in Rusitec fermenters

International Journal of Biological Macromolecules, 2018
Bioactive polysaccharides and oligosaccharides (POSs) have been used as safe non-antibiotic alternatives in animal diets; however, only limited data are available on their effects in rumen manipulation. This study was undertaken to systematically evaluate and compare the efficacies of six different bioactive POSs (10g/kg diet) with respect to ruminal ...

PSXIII-20 Comparing the nutritive value of corn stover, corn silage and Pleurotus ostreatus spent mushroom substrate using rumen simulation technique (RUSITEC) as a ruminant feed.

Journal of Animal Science
This study compared the nutritive value of corn stover, corn silage and spent mushroom (Pleurotus ostreatus) substrate (SMS) in addition to corn silage and SMS mixture (1:1, w/w) using the rumen simulation technique (RUSITEC) system with sixteen ...

PSXII-25 Effects of Aspergillus oryzae-derived prebiotics on ruminal fermentation and the microbiome in an artificial rumen system (Rusitec).

Journal of Animal Science
Prebiotics that stimulate beneficial microbes have had varying success in improving animal health and enhancing production efficiency. Aspergillus oryzae prebiotics (AOP) are produced from a multi-step fermentation process of a selected strain that ...

Effects of by-product feed inclusion in a grass hay-based diet on nutrient disappearance, total gas and methane production, rumen fermentation and protozoal populations in an artificial rumen (RUSITEC)

Animal Production Science
Context Dietary manipulation can reduce enteric methane in beef cattle but limited options exist for perennial forage-based diets. Aims An artificial rumen system (RUSITEC) was used to assess the effects of including quinoa screenings, flax screenings ...

The Effect of Saliva with Different Nitrogen Compositions on Ruminal Fermentation in a Rumen Simulator Technique (Rusitec®) System Fed a Lactating Dairy Cow Diet

Fermentation
In vitro methods have advanced research on rumen microbiology and fermentation. However, artificial saliva formulation may need adjustments, particularly in urea content, for modern diets, warranting further research.
