“…Dohme et al (2000) observed from in vitro studies that with the addition of 53 g kg -1 DM of palm kernel oil, coconut oil, or canola oil, CH 4 production was reduced by 34, 21 or 20%, respectively. Machmuller and Kreuzer (1999) daily CH 4 production was reduced by 28 and 73%, respectively. Mathison (1997) reported that CH 4 production was reduced by 33 when 4% of canola oil was added to a diet containing 85% concentrate in a feedlot study.…”

“…Fats have also been shown to depress CH 4 production (Dong et al 1997a;Machmuller and Kreuzer 1999;Dohme et al 2000). It has been shown that the medium chain fatty acids (C 8 -C 16 ) cause the greatest reduction in CH 4 production (Dohme et al 2000).…”

“…Although the addition of fats appears to reduce CH 4 production, excessive addition would not result in increased energy availability to the animal due to depressed fiber digestion. Also, saturated fatty acids such as coconut oil have been shown to have a toxic effect on protozoa and methanogens (Dong et al1997a;Machmuller and Kreuzer 1999). Feeding 3.5 and 7% coconut oil reduced ciliate protozoa to 1.0 ( 10 5 mL -1 and 0.3 ( 10 5 mL -1 , respectively, compared to the controls (1.7 ( 10 5 mL -1 ) (Machmuller and Kreuzer 1999).…”

. 2004. Mitigation strategies to reduce enteric methane emissions from dairy cows: Update review. Can. J. Anim. Sci. 84: 319-335. Enteric methane (CH 4 ) emission is a major contributor to Canadian greenhouse gas emissions, and also a loss of feed energy during production. The objective of this paper is to provide an update on current management practices and new dietary strategies recently proposed to reduce CH 4 emissions from ruminants. Existing mitigation strategies for dairy, e.g., the addition of ionophores, fats, use of high-quality forages, and increased use of grains, have been well researched and applied. These nutritional changes reduce CH 4 emissions by manipulating ruminal fermentation, directly inhibiting methanogens and protozoa, or by diverting hydrogen ions away from methanogens. Current literature has identified new CH 4 mitigation options. These include the addition of probiotics, acetogens, bacteriocins, archaeal viruses, organic acids, plant extracts (e.g., essential oils) to the diet, as well as immunization, and genetic selection of cows. These new strategies are promising, but more research is needed to validate these approaches and to assess in vivo their effectiveness in reducing CH 4 production by dairy cows. It is also important to evaluate CH 4 mitigation strategies in terms of the total greenhouse gas budget and to consider the cost associated with the various strategies. More basic understanding of the natural differences in digestion efficiencies among animals as well as a better knowledge of methanogens and their interaction with other organisms in the rumen would enable us to exploit the potential of some of the new CH 4 mitigation strategies for dairy cattle production.

Stratégies visant à réduire les dégagements de méthane entérique des vaches laitières: bilan. Can. J. Anim. Sci. 84: 319-335. Le méthane (CH 4 ) d'origine entérique contribue dans une large mesure aux émissions canadiennes de gaz à effet de serre et entraîne une perte de l'énergie tirée des aliments durant la production. Le présent article fait le point sur les pratiques de zootechnie actuelles et sur les stratégies d'engraissement récemment proposées pour réduire les dégagements de CH 4 des ruminants. Les stratégies d'atténuation existantes (addition d'ionophores, matière grasse, utilisation de fourrages de grande qualité, plus grande utilisation de grains) ont fait l'objet de maintes recherches et sont désormais bien appliquées. Les changements nutritionnels qu'elles introduisent diminuent les émissions de CH 4 en modifiant la fermentation dans le rumen, en inhibant directement la production de méthanogènes et la population de protozoaires ainsi qu'en détournant les ions hydrogène des méthanogènes. La documentation scientifique mentionne de nouvelles méthodes pour atténuer la libération de CH 4 . Ces méthodes comprennent l'ajout de probiotiques, d'acétogènes, de bactériocine, de virus archaïques, d'aci...

“…Dietary fats rich in saturated mediumchain length fatty acids (MCFA) have been shown to suppress CH 4 formation in vivo (Machmüller and Kreuzer, 1999). At 39°C, lauric (C 12 ) and myristic acid (C 14 ), two MCFA, are anti-methanogenic both in ruminal fluid (Dohme et al, 2001) and in sludge (Koster and Cramer, 1987), while saturated fattyacids (SFA) of longer-chain length such as palmitic acid (C 16 ) and stearic acid (C 18 ) did not exert this effect in vitro (Dohme et al, 2001;Soliva et al, 2004;Zhang et al, 2008) and in vivo (Hristov et al, 2009).…”

“…Despite the possibility of a methane reduction greater than 40% when high levels of lipids are added (Machmuller and Kreuzer, 1999;Jordan et al ., 2006b), a reduction from 10 to 25% is more likely to be obtained (Beauchemin et al ., 2008). It is recommended that lipid supplementation does not exceed 6 to 7% DM to avoid the decrease of VDMI.…”

SummaryLivestock farming in Latin America has been criticized because of its large greenhouse gas (GHG) production resulting from the use of degraded forage and low-efficiency production performance. Agriculture contributes a significant amount of the three main greenhouse gases: methane (CH 4 ), carbon dioxide (CO 2 ), and nitrous oxide (N 2 O). Methane has a global warming potential 25 times greater than CO 2. Enteric methane is an important greenhouse gas responsible for approximately 15% of global warming. The trend and legal obligation of mitigating greenhouse gas emissions will likely directly influence improved efficiency of livestock systems, including animal nutrition and handling. The development of mitigation strategies and the viability of their practical applications have been researched around the world. Various nutritional strategies to mitigate enteric methane have been studied and developed. All of them differ in terms of viability, cost, and acceptance by the producers. Their adoption should be based on the capacity to reduce methane emissions in association with economic viability and animal performance. Animal performance improvement will be achieved in production systems (mainly those related to efficient forage use) associated with good management of nutrition, health and reproduction. These are important strategies to consolidate Brazil as a food producer to the world, respecting the demands regarding land, water, biodiversity conservation and emission of greenhouse gases.Keywords: climate change, global warming, greenhouse gas, livestock, sustainability. 125Rev Colomb Cienc Pecu 2015; 28:124-143 Ribeiro LG et al. Methane mitigation in ruminants: a review ResumenLa industria pecuaria latinoamericana ha sido criticada por la emisión significativa de gases con efecto invernadero (GHG). Dicha crítica se fundamenta en los bajos indicadores zootécnicos observados en los sistemas de producción animal basados en pasturas degradadas o que se encuentran por debajo de su potencial de producción. La industria agropecuaria contribuye de manera significativa con la emisión de los tres principales GHG: metano (CH 4 ), dióxido de carbono (CO 2 ) y óxido nitroso (NO 2 ). El gas metano tiene un potencial de calentamiento global 25 veces mayor que el de CO 2 . El metano entérico es un importante gas de efecto invernadero, que es responsable de aproximadamente el 15% del calentamiento global. La tendencia o la obligación legal de mitigar las emisiones de GHG tendrá una influencia directa sobre la necesidad del aumento de la eficiencia zootécnica en los sistemas pecuarios relacionado con el manejo nutricional de los animales que deberá ser adoptado. El desarrollo de estrategias de mitigación y la viabilidad de su aplicación práctica representan áreas de investigación alrededor del mundo. Existen diversas estrategias nutricionales que se han estudiado y desarrollado con el fin de mitigar el metano entérico. Dichas estrategias presentan diferentes viabilidades, costos y posibilidades para que sean aceptadas por...
