“…The reduction was observed only for higher concentrations (4 mg/ml). Similar conclusions were drawn by other authors (Staerfl et al, 2010;Wang et al, 2011;Zmora et al, 2012b and2012c). Moreover, Bodas et al (2012) demonstrated that low saponin concentrations indirectly influence methane production in the rumen by reducing the number of protozoa, whereas higher saponin concentrations have direct negative effect on methanogens.…”

“…Therefore, growth and development of Achaea directly depends on the population of microorganisms, for example, those utilizing cellulose, which leads to an increase in the concentration of hydrogen (substrate for the process of methanogenesis), a by-product of crude fiber hydrolysis (Morvan et al, 1996;Wang et al, 2011). Syntropic interaction was demonstrated between rumen bacteria and methanogens by Wolin et al (1997).…”

“…This effect was noted when using a mixed rumen culture for in vitro studies, but not when pure cultures of M. ruminantium were tested. Other researchers used 3 g/day of tea saponins in sheep diets and concluded that there was no effect on the populations of methanogens (Mao et al, 2010;Zhou et al, 2011). Earlier in vitro research had suggested mitigation of the process of methanogenesis without reduction in the number of methanogens with the use of saponins from Sapindus saponaria or tea saponins (Hess et al, 2003;Hu et al, 2005).…”

A wide range of plant bioactive components (phytochemicals) have been identified as having potential to modulate the processes of fermentation in the rumen. The use of plants or plant extracts as natural feed additives has become a subject of interest not only among nutritionists but also other scientists. Although a large number of phytochemicals (e.g. saponins, tannins and essential oils) have recently been investigated for their methane reduction potential, there have not yet been major breakthroughs that could be applied in practice. A key tenet of this paper is the need for studies on the influence of plant components on methane production to be performed with standardized samples. Where there are consistent effects, the literature suggests that saponins mitigate methanogenesis mainly by reducing the number of protozoa, condensed tannins both by reducing the number of protozoa and by a direct toxic effect on methanogens, whereas essential oils act mostly by a direct toxic effect on methanogens. However, because the rumen is a complex ecosystem, analysis of the influence of plant components on the populations of methanogens should take into account not only the total population of methanogens but also individual orders or species. Although a number of plants and plant extracts have shown potential in studies in vitro, these effects must be confirmed in vivo.Keywords: ruminants, methane, tannins, saponins, essential oils ImplicationsThis review demonstrates that plant phytochemicals can have important effects on rumen methanogens, either by affecting methanogens directly and/or indirectly by affecting rumen protozoa. Modulation of the rumen microbiota, including methanogens and protozoa, with plant extracts such as saponins, tannins and essential oils has implications in improvement of animal nutrition through decreased dietary energy loss, and in limitation of the negative impact on the environment through mitigation of methane production.

“…Saponin forms a complex with cholesterol in the cell membrane of protozoa, changes its permeability and induces cell lysis . Supporting the present finding, studies performed by other authors also demonstrated a decrease of protozoa population by addition of saponin (Zhou et al, 2011;Ramos-Morales et al, 2017). A meta-analysis study of Jayanegara et al (2014) revealed that all saponin sources evaluated, i.e.…”

This study aimed to observe the effects of rice straw ammoniation and supplementation of Paraserianthes falcataria and Sapindus rarak on rumen fermentation and methane production in vitro. Rice straw was ammoniated by adding 2% urea. Rice straw, ammoniated rice straw, P. falcataria leaves and S. rarak fruits were oven-dried and finely ground. Experimental treatments were arranged as follow: rice straw (T1), ammoniated rice straw (T2), T2 80% + P. falcataria 20% (T3), T2 60% + P. falcataria 40% (T4), T2 80% + P. falcataria 10% + S. rarak 10% (T5), and T2 60% + P. falcataria 20% + S. rarak 20% (T6). An amount of 1 g sample from each treatment was added with 100 ml rumen fluid and buffer mixture (1:2 v/v), and incubated in a water bath at 39 ºC for 48 h. The incubation was performed in four replicates and each replicate was represented by four incubation bottles. Results showed that urea treatment increased gas production of rice straw at 24 and 48 h, higher ammonia production, higher IVDMD, and lower methane production as compared to the untreated rice straw (P<0.05). Addition of P. falcataria or S. rarak at lower level produced similar ammonia concentration as ammoniated rice straw whereas their addition at higher level decreased ammonia concentration (P<0.05). Paraserianthes falcataria addition to ammoniated rice straw decreased protozoa population (P<0.05) and S. rarak further decreased the fauna population (P<0.05) as well. Inclusion of S. rarak at 20% DM (T6) produced the lowest methane production both at 24 and 48 h after incubation and lowest methane production per unit of DM degraded. It was concluded that ammoniation of rice straw improved its nutritional quality with lower methane production, and its mixture with P. falcataria and S. rarak further increased the quality and lower the production of methane, respectively.

“…A los taninos y a las saponinas se les atribuye un efecto directo sobre los metanógenos y los protozoos, relacionados con la formación de complejos con la pared celular, lo cual provoca cambios morfológicos (Smith et al, 2005;Zhou et al, 2011) e induce deficiencias nutricionales, lisis y muerte de las células . Teniendo en cuenta que alrededor del 25% de los metanógenos ruminales vive en asociación con protozoos se espera que una reducción en los últimos disminuya los primeros (Newbold et al, 1997).…”

The aim of this study was evaluated by in vitro, the effect of mixing wild sunflower (Tithonia diversifolia), kikuyu (Cenchrus clandestinum) and concentrated feed, with the addition of polyunsaturated fatty acids (AGPI) on the production of methane (CH4 ml/g MSd), dry matter digestibility (%DIVMS) and production of volatile fatty acids (AGV). The research was conducted in NUTRILAB laboratory (Medellin, Colombia) in September 2015. Three combinations of AGPI rich lipid sources were used with a total maximum inclusion level corresponding to 3% of incubated dry matter. Combinations of lipid sources were: SAGPI1: 0.5% soya oil, 0.5% sish oil, 2% rich in omega 3 bypass fat. SAGPI2: 1% Soya oil, 0.5% fish oil, 1.5% bypass fat rich in omega 3. SAGPI3: 2.5% Soya oil, 0.5% fish oil. A source of bypass fat (GSP) was also used. The results were processed using pre-planned test comparisons through the PROC MIXED-SAS.The methane production in vitro decreased (p<0.05), while the dry matter digestibility increased (p<0.05) 24 and 48 hours after wild sunflower was include and / or AGPI or both into the mixtures. In the molar ratio of AGV (%), acetic acid showed an increased presence. The inclusion of forage like wild sunflower and sources of AGPI supplementation in cattle, could be a strategy to reduce methane emissions without causing a detriment to the ruminal fermentation.
