“…This is in agreement with some previous reports, both tannin phenolics (Carulla et al, 2005;Puchala et al, 2005) and non tannin phenolics (Jayanegara, 2009b). The mechanisms of phenolic compounds in inhibiting methane formation in ruminants have been proposed by Tavendale et al (2005), i.e.…”

This research was aimed to explore the use of multivariate statistics i.e. principal component analysis (PCA) in identifying and integrating variables related to forage quality and ruminal methane production, and in classifying forage species into both characteristics. Seventeen plants were used as a database for the above mentioned purposes. Plant samples were determined for their chemical composition, cumulative gas production (represents the nutrient degradation) and methane production after 24 hours of fermentation period using the Hohenheim gas test. The results showed that the PCA could clearly identify factors related to forage quality and methane production and separated them into different principal components (PC). The obtained PC1 was related to methane production and substantially influenced positively by crude protein, NDF, ADF (positive), total phenols, total tannins, condensed tannins and tannin activity (negative). On the other hand, the obtained PC2 was related to cumulative gas production (forage quality) and substantially influenced by crude protein (positive), NDF, ADF and condensed tannins (negative). Classification and screening of forages that have high quality and low methane production are possible using the PCA technique. Rhenum undulatum, Peltiphyllum peltatum and Rhus typhina were found to have such desired characteristics.

“…Many plants contain tannins, and these are often tropical shrub legumes. Animal trials with plants or extracts of condensed tannin-containing Lotus corniculatus, Lotus pedunculatus and Acacia mearnsii reduced CH 4 production in small ruminants (sheep, alpaca, goats) by up to 30% without altering digestibility (PinaresPatiñ o et al, 2003c; Carulla et al, 2005;Puchala et al, 2005). More recently, Tiemann et al (2008) reported that the inclusion of the tannin-rich shrub legumes species Callinadra calothyrsus and Fleminga macrophylla in the diet reduced CH 4 emissions in growing lambs by up to 24%, but this was associated with reduced organic matter and fibre digestibility.…”

Decreasing enteric methane (CH 4 ) emissions from ruminants without altering animal production is desirable both as a strategy to reduce global greenhouse gas (GHG) emissions and as a means of improving feed conversion efficiency. The aim of this paper is to provide an update on a selection of proved and potential strategies to mitigate enteric CH 4 production by ruminants. Various biotechnologies are currently being explored with mixed results. Approaches to control methanogens through vaccination or the use of bacteriocins highlight the difficulty to modulate the rumen microbial ecosystem durably. The use of probiotics, i.e. acetogens and live yeasts, remains a potentially interesting approach, but results have been either unsatisfactory, not conclusive, or have yet to be confirmed in vivo. Elimination of the rumen protozoa to mitigate methanogenesis is promising, but this option should be carefully evaluated in terms of livestock performances. In addition, on-farm defaunation techniques are not available up to now. Several feed additives such as ionophores, organic acids and plant extracts have also been assayed. The potential use of plant extracts to reduce CH 4 is receiving a renewed interest as they are seen as a natural alternative to chemical additives and are well perceived by consumers. The response to tannin-and saponincontaining plant extracts is highly variable and more research is needed to assess the effectiveness and eventual presence of undesirable residues in animal products. Nutritional strategies to mitigate CH 4 emissions from ruminants are, without doubt, the most developed and ready to be applied in the field. Approaches presented in this paper involve interventions on the nature and amount of energy-based concentrates and forages, which constitute the main component of diets as well as the use of lipid supplements. The possible selection of animals based on low CH 4 production and more likely on their high efficiency of digestive processes is also addressed. Whatever the approach proposed, however, before practical solutions are applied in the field, the sustainability of CH 4 suppressing strategies is an important issue that has to be considered. The evaluation of different strategies, in terms of total GHG emissions for a given production system, is discussed.Keywords: methane, greenhouse gases, ruminant, mitigation strategies Implications Methane (CH 4 ) mitigation in ruminants is possible through various strategies. Today, the feeding management approach is the most developed. Other strategies (biotechnologies, additives) are promising but the diversity and plasticity of functions of the rumen bacterial and methanogenic communities may be a limiting factor for their successful application. A possible selection of animals on CH 4 production and more likely on digestive processes is evocated. In any case, before practical solutions are proposed for field application more research in vivo is needed. The sustainability of CH 4 -suppressing strategies is also an important issue and they mi...

“…Reference [34] reported that, roughage based diets might increase the tVFA and decrease the A:P ratio. Both reference [25], and [35] reported that tVFA varies with the response to phenolic compounds in the diet by depressing fibre degradation, with the extent of which depends upon the chemical structure of the phenolic compound and the species of methanogen [36]. Although not observed in this study, reference [7] reported that an increasing pH might decrease tVFA.…”

Abstract-The aim of this study was to increase the nutritive value of coffee, green and oolong tea residues and assess if the fermented residues have the potential to mitigate enteric methane emissions. A mixed microbial culture (20 g/kg) was added to each residue and the mixture incubated for 3 d at 35°C (anaerobically) and 2 weeks at 30°C (aerobically). Unfermented and fermented beverage residues were assayed for their saccharide and ethanol content. Four separate total mixed rations (TMR) were prepared using the three fermented beverage residues and hay (control). The fermented residues (2 g dry matter (DM)) were individually mixed with hay (3 g DM) and concentrate (5 g DM) and the in vitro rumen methane output was quantified during the 24 h incubation period using the continuous gas quantification system. The fermented residues of coffee, oolong tea and green tea had higher concentrations of cellotriose, cellobiose and xylobiose than the corresponding unfermented residues. Ethanol concentration was higher in the fermented coffee and green tea residues than in their respective unfermented residues. The methane output (L CH4/24 h) from the TMR containing fermented residues of coffee (0.118 L), oolong tea (0.127 L) and hay (control; 0.123 L) did not differ, but the methane output was lower for all compared to the TMR containing fermented green tea residue (0.141 L). The results suggest that fermented coffee, oolong tea and green tea residues are a potentially good source of protein and energy, and fermented residues of coffee caused a numerical decrease methane output.Index Terms-Beverage residues, in vitro, methane, mixed microbial culture.
