“…However, the trend of VFA production observed in this study was not in line with the report of Shingfield et al (2008) where a decline in acetate concentration was observed with increasing levels of dietary sunflower oil. Contrary to earlier findings where increasing levels of dietary oil were associated with decrease in the acetate-to-propionate ratio (Shingfield et al 2008;Jacob et al 2012), Carotino oil did not reduce the acetate-to-propionate ratio. In addition, the shift in VFA production from acetate to propionate that was reported to be associated with increasing levels of dietary oil was not observed in this study.…”

“…This observation contradicts the findings of Jacob et al . () in which supplementation of soybean oil and sunflower oil each at 6% was associated with a significantly higher ruminal pH. Similarly, Jalč and Čerešňáková () observed significantly higher ruminal pH values when each of sunflower oil, rapeseed oil and linseed oil at 10% was supplemented.…”

“…) and other fermentation parameters (Jacob et al . ) crucial for the overall wellbeing of the rumen ecology and the animal. The effects of dietary fats on rumen fermentation depend on the degree of saturation, origin, fatty acid composition and the quantity of the fat, and the concentrate to forage ratio of the basal diet (Szumacher‐Strabel et al .…”

The study appraised the effects of Carotino oil on in vitro rumen fermentation, gas production, metabolism and apparent biohydrogenation of oleic, linoleic and linolenic acids. Carotino oil was added to a basal diet (50% concentrate and 50% oil palm frond) at the rate of 0, 2, 4, 6 and 8% dry matter of the diet. Rumen inoculum was obtained from three fistulated Boer bucks and incubated with 200 mg of each treatment for 24 h at 39°C. Gas production, fermentation kinetics, in vitro organic matter digestibility (IVOMD), volatile fatty acids (VFA), in vitro dry matter digestibility (IVDMD), metabolizable energy and free fatty acids were determined. Carotino oil did not affect (P > 0.05) gas production, metabolizable energy, pH, IVOMD, IVDMD, methane, total and individual VFAs. However, Carotino oil decreased (P < 0.05) the biohydrogenation of linoleic and linolenic acids but enhanced (P < 0.05) the biohydrogenation of oleic acid. After 24 h incubation, the concentrations of stearic, palmitic, pentadecanoic, myristic, myristoleic and lauric acids decreased (P < 0.05) while the concentration of linolenic, linoleic, oleic and transvaccenic acids and conjugated linoleic acid (CLAc9t11) increased (P < 0.05) with increasing levels of Carotino oil. Carotino oil seems to enhance the accumulation of beneficial unsaturated fatty acids without disrupting rumen fermentation.

“…Al igual que en la presente investigación, Jacob et al (2012) no encontraron disminución en el total de AGV al adicionar aceite de soya en proporciones de 4,5% de la MS en dietas para bovinos, pero si encontraron una disminución significativa sobre los AGV, al aumentar la dosis de aceite a niveles del 6% de la MS. Asimismo, Benchaar et al (2012) suplementaron con una fuente de AGPI (aceite de lino) en niveles de hasta 4% de la MS, en una ración totalmente mezclada, y tampoco encontraron disminución del total de AGV. El nivel y la fuente de inclusión de lípidos determinan en gran medida los productos de la fermentación ruminal entre ellos la proporción de AGV (Toral et al, 2009).…”

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.
