“…Furthermore, essential oils, organosulphur compounds and flavonoids can affect CH 4 production by direct inhibition of methanogens, with simultaneously no effect on the protozoa population (Patra and Saxena, 2010). Broudiscou et al (2000) found that an extract of Salvia officinalis L. rich in flavonoids, decreased methanogenesis in continuous culture of ruminal microorganisms without altering the protozoa population. In our study, 200 mg of dried sage leaves mitigated CH 4 production correlated to both methanogens and the protozoa population.…”

“…The discrepancies among the studies may be caused by different sources of bioactive compounds, hence different mechanisms of action. Broudiscou et al (2000) used purified plant secondary metabolites or plant extracts. The dried sage leaves used in the present study contained phytofactors and some other compounds that can interact with PSM and rumen microorganisms (Szumacher-Strabel and Cieslak, 2010).…”

Dried leaves of Salvia officinalis L., a rich source of phytofactors, were evaluated for their effect on methane production, microbial population, and basic parameters of rumen fermentation in a batch culture system. A 400 mg mixture of meadow hay and barley meal at a ratio of 60:40 was used as the substrate. Dried leaves of Salvia officinalis L. were added to the substrate at six levels (4, 10, 20, 40, 100, and 200 mg). A wide range of dried Salvia officinalis L. leaves, in quantities even up to 50% of the substrate, was used to test the effect of increasing amounts of phytofactors in the investigated cultures, mostly on methane production. CH 4 production was significantly mitigated by supplementation with 200 mg of sage per incubation vessel. The supplement affected the protozoa and methanogen populations which indicates that methane emission is associated with these populations; in vitro dry matter digestibility decreased linearly, however. Although Salvia officinalis L. seems to be a plant for which there may be a use in ruminant nutrition and the presented results suggest that the optimal level of Salvia officinalis is between 100 and 200 mg, further investigations under long-term in vivo conditions are necessary, as are the determination of the optimum dose and the active agent.

. 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...

“…Em estudos sobre a microbiota ruminal, Broudiscou et al (2000) testaram a própolis e observaram aumento de 10% na produção de propionato em 10,3% e redução da população de protozoários. A própolis também foi eficiente em diminuir a produção de amônia de fontes de nitrogênio, tanto in vitro como in vivo (Stradiotti Jr. et al, 2004;Oliveira et al, 2006).…”

RESUMO -Avaliaram-se os efeitos da utilização de produtos contendo própolis em duas concentrações (B e C) e duas extrações alcoólicas (1 e 3) e de monensina sódica em dieta à base de forragem sobre o consumo, a digestibilidade total e parcial e as características ruminais em bovinos. Utilizaram-se quatro bovinos da raça Holandesa, castrados, com peso corporal de 221 ± 21 kg, canulados no rúmen, em delineamento experimental quadrado latino 4 × 4. As dietas experimentais foram constituídas de 72,5% de volumoso e 27,5% de concentrado e apresentaram 14,4% de PB e 67% de nutrientes digestíveis totais (NDT), diferindo apenas quanto à presença de aditivos. Os consumos médios de matéria seca e nutrientes, não foram afetados pelas dietas, exceto o de NDT, que foi maior nos animais alimentados com a dieta controle. O fornecimento dos aditivos, principalmente própolis, reduziu a digestibilidade total de matéria seca, proteína bruta e NDT.A digestibilidade total da fibra em detergente neutro (FDN) foi semelhante entre aditivos e menor que nos animais controle.A inclusão de própolis refletiu em menor pH ruminal e maiores produções de acetato e AGV totais e a monensina propiciou a menor razão acetato:propionato. A adição dos aditivos avaliados tem efeito negativo sobre a concentração e consumo de energia digestível de dietas à base de forragem fornecida para bovinos em crescimento.Palavras-chave: ácidos graxos voláteis, digestibilidade parcial, nitrogênio amoniacal, pH ruminal, taxa de diluição Digestibility and ruminal parameters of diet based on forage with the addition of propolis and sodium monensin for steers ABSTRACT -It was evaluated the effects of using products containing propolis in two propolis concentrations (B and C) and two alcoholic extractions (1 and 3) and sodium monensin in forage based diet on intake, total and partial digestibility and ruminal characteristics in cattle. It was used four Holstein castrated bovines, with body weight of 221 ± 21 kg, implanted with ruminal cannulla, in a 4 × 4 Latin square experimental design. The experimental diets were composed of 72.5% roughage and 27.5% concentrate and had 14.4% crude protein and 67% of total digestible nutrients (TDN), only differing to the presence of additives. The average intake of dry matter and nutrients did not differ among diets, except for the intake of TDN that was higher for animal fed control diet. The supply of additives, mainly propolis, reduced the total digestibility of dry matter (DM), crude protein (CP) and total digestible nutrients (TDN). The total digestibility of neutral detergent fiber was similar among additives and it was lower than the control animals. The inclusion of propolis reflected in lower pH and production of acetate and total volatile fatty acids and monensin resulted in lower acetate:propionate ratio. The addition of the evaluated additives has negative effect on the concentration and intake of digestible energy of roughage based diets for growing cattle.
