“…Our results strongly suggest that flavonoids contribute the most to reducing CH 4 production and it may be particularly useful for a general screening for plants possessing antimethanogenic activity. Otherwise, TF and CT fractions are both associated with a lower CH 4 emission, however, the mechanisms through which they decrease CH 4 appear to differ.This supports previous studies which reported that ruminal CH 4 production may be lower when using diets containing flavonoids (Garcıa-Gonzalez et al, 2008a b; Balcells et al, 2012;Oskoueian et al, 2013 ;Seradj et al, 2014). But this is not always the case (Broudiscou et al, 2000(Broudiscou et al, , 2002.…”

The objective of this study was to evaluate the effects of two plants rich in phenolics compounds on ruminal fermentation, methane production and related microbial diversity using in vitro gas production technique (IVGPT). 25 mg of the two plant extracts added to 1.0 g of mixture of alfalfa hay, ryegrass hay and corn (5, 2, 3) were incubated with 30 ml of buffered rumen fluid (1: 2) in 120 ml serum bottles. After 24h, the incubation was stooped and the inoculants were determined for pH, ammonia-N, VFA, truly organic matter digestibility, methanogens and protozoa quantification using real time PCR technique. In vitro gas production was recorded and methane concentration was determined at 3, 6, 9, 12 and 24h of incubation. Results showed that methane and ammonia nitrogen production was significantly reduced (p ˂ 0.05), propionate production was increased significantly (p ˂ 0.05), while no significant effect was registred for pH, tVFA and organic matter digestibility comparatively to the control. Real time PCR indicated that the ciliate protozoa population in the two added extracts was decreased (p ˂ 0.05), while no effect was observed on methanogens population. Among phenolics fractions, total flavonoids had the closest relationship with CH 4 production (r = -0.916, p ˂ 0.01) followed by total phenols (r = -0.861, p ˂ 0.01) and condensed tanins (r = -0.538, p ˂ 0.05). In conclusion, the plants rich in flavonoids might be promising to be used as a potent antimethanogenic additive for decreasing CH 4 while they obviously enhance microbial biomass production and fermentation effeciency.

“…Various phytochemicals have been shown to modulate rumen fermentation favourably, and to inhibit methane production in the rumen Saxena, 2010, 2011;Seradj et al, 2014). Tree leaves, which contain tannins and saponins in varying amounts, may be incorporated in diets to mitigate enteric methane emissions (Patra and Saxena, 2010).…”

“…In the current study, we investigated the effect of supplementation of resveratrol on in vitro methane production, rumen fermentation and prokaryotic communities using the 16S rRNA sequencing method under two different diets (forage‐based and concentrate‐based) and two time points (12 and 24 h) that reflect the types of diet of fattening lambs and feeding regimens in practice respectively. In vitro fermentation techniques involve the incubation of substrates (usually the diets) with a rumen fluid, which have been widely used to evaluate the effect of polyphenols such as tannins (Jayanegara et al , 2015; Witzig et al , 2018) and flavonoids (Oskoueian et al , 2013; Seradj et al , 2014) on VFA production and methane production. Although the results obtained from in vitro fermentation techniques cannot completely reflect or replace those obtained from in vivo studies (Benchaar et al , 2008; Oh and Hristov, 2016), they offer a rapid and less expensive alternative to evaluate nutrient utilization in vivo (Rymer et al , 2005).…”

This study aimed to investigate the effect of resveratrol on methane production, rumen fermentation and microbial composition under high-concentrate (HC) and high-forage (HF) diets using the in vitro fermentation system. A total of 25 mg of resveratrol was supplemented into 300 mg of either HC or HF diet. Methane production, total volatile fatty acid (VFA) concentration, molar proportion of VFA, metabolites of resveratrol and prokaryotic community composition were measured after 12 and 24 h of in vitro fermentation. Resveratrol reduced methane production (ml per mg of dry matter degraded) by 41% and 60% under both HC and HF diets (P < 0.001), respectively, and this result could be associated with the lower abundance of Methanobrevibacter (P < 0.001) in response to resveratrol. The molar proportion of propionate was significantly higher in the resveratrol group only under the HC diet (P = 0.045). The relative abundance of 10 bacterial genera was affected by the three-way interaction of treatment, diet and time (P < 0.05). Resveratrol was partly converted to dihydroresveratrol after 24 h of fermentation, and its degradation could be associated with microbes belonging to the order Coriobacteriales. Our results suggest that multiple factors (e.g. diet and time) should be considered in animal experiments to test the effect of polyphenol or other plant extracts on rumen fermentation, methane emission and microbial composition.
