“…Compared to LH+WB diet, the DM and OM degradability of LH+WB+SO+TE diet was lower (P < 0.05 and P < 0.001). The negative effect of dietary PUFA on fibre digestion and organic matter rumen degradation was also reported by Machmuller et al (1998) in RUSITEC and by Wachira et al (2000) in in vivo experiments in wethers. The values of pH were influenced by the T (P < 0.001).…”

ABSTRACT:The application of Thamnidium elegans fungal strain CCF 1456 (TE) for effective utilization of various agroindustrial materials creates new perspectives for animal cereal diets enriched with microbial γ-linolenic acid (GLA). Diets consisting of lucerne hay (LH) plus prefermented cereals (wheat bran/spent malt grains, WB+TE or WB+TE enriched with sunflower oil, WB+SO+TE in the first experiment and ground maize grains, GC+TE in the second experiment) were used in the artificial rumen. We examined their effect on the rumen fermentation pattern and lipid metabolism. The diet affected the results of degradability of dry matter, organic matter, neutral detergent fibre and acid detergent fibre of LH+WB diets (P < 0.05 and P < 0.01). The GLA daily output of prefermented diet substrates LH+WB+TE and LH+WB+SO+TE, or LH+GC+TE was higher compared to the non-prefermented LH+WB or LH+GC, respectively (P < 0.05 and P < 0.01). Daily outputs of trans11 oleic (TVA) of the LH+GC+TE diet were higher versus the non-prefermented LH+GC (P < 0.01). The biohydrogenation of fatty acids (C18:1 cis9 oleic, C18:2 linoleic, C18:3n-3 alpha-linolenic, C18:3n-6 GLA and total FA) of prefermented cereal diets was not influenced. Cereal diets containing microbial GLA might positively enhance GLA daily outputs in the RUSITEC effluent, but they are not effective enough to decrease the biohydrogenation of unsaturated fatty acids.

“…Linolenic acid has been shown to have a higher effect on CH 4 than linoleic acid in vitro and linseed oil had the same effect as coconut oil in vivo (Newbold et al, 1996). On the contrary, sunflower seed (rich in linoleic acid) had a similar depressive effect as coconut oil on CH 4 production, and this effect was higher than rapeseed (rich in oleic acid), and especially than linseed (rich in linolenic acid), in vitro (Machmü ller et al, 1998) and in vivo (Machmü ller et al, 2000). Recently, Beauchemin et al (2009) reported that CH 4 production in dairy cows was more affected by linseed and rapeseed (217% on average) than by sunflower seeds (210%).…”

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...

“…Además, se relaciona el potencial antimetanogénico de los lípidos con un efecto tóxico sobre los protozoos y metanógenos en rumen (Janssen, 2010). La reducción de CH 4 inducida por la adición de fuentes lipídicas a la dieta en rumiantes puede alcanzar hasta un 50% (Machmüller et al, 1998). Se han encontrado reducciones de 5,6% de metano por cada unidad porcentual de lípidos adicionado a la ración en bovinos (Beauchemin et al, 2008).…”

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.
