In this study, we evaluated the influence of several lipid sources on ruminal digestion and fermentation as well as the extent of fatty acid biohydrogenation in the rumen.
Thus, if ruminal biohydrogenation can be controlled, it will be possible to increase the transfer of these PUFA for milk and milk derivatives.
2008), and others are degraded into monounsaturated and SFAs in the rumen by microbial biohydrogenation.
Moreover, the increased C18:1 content with SO and SS can be a result of partial biohydrogenation of C18:2 and C18:3 FA and of the desaturation of C18:0 in the mammary gland (Kennelly, 1996).
As the PF is partially inert in the ruminal environment, less biohydrogenation is observed in these acids in the rumen (Fiorentini, 2013).
Nevertheless, ruminal biohydrogenation (BH), which transforms unsaturated fatty acids (UFA) into SFA, is a major concern due to SFA is detrimental for human health.
Significance of phenolic compounds in tropical forages for the ruminal bypass of polyunsaturated fatty acids and the appearance of biohydrogenation intermediates as examined in vitro.
Some authors have explained these effects with the "biohydrogenation theory" which tells that high dietary unprotected plant oils alter the pathways of rumen biohydrogenation to produce unique fatty acid intermediates, some of which are potent inhibitors of milk fat synthesis (Bauman and Griinari, 2001).
Tannins reduced ruminal biohydrogenation (BH) through the inhibition of the proliferation of ruminal microorganisms rather than by a direct interaction of tannins with the enzymes that operate in the BH pathway (Vasta et al.
Although increasing the proportion of polyunsaturated fatty acids (PUFA) in milk is limited due to extensive biohydrogenation of these FA in the rumen, supplementing linseed to dairy cattle increased the proportion of cis-9,trans-11-18:2 (c9,t11 CLA) and n-3 FA, particularly linolenic acid, EPA and DHA in milk (Glasser et al.
Copper has a high potential for reduction, and in rumen it can act on reduction reactions such as NADPH and NADH, interfering in the microbial biohydrogenation of unsaturated fatty acids.
Australian plants with potential to inhibit bacteria and processes involved in ruminal biohydrogenation of fatty acids.
Biohydrogenation of fatty acids and digestibility of fresh alfalfa or alfalfa hay plus sucrose in continuous culture.
