Effect of Quebracho tannin extract on soybean and linseed oil biohydrogenation by solid associated bacteria: an in vitro study
An <em>in vitro</em> trial was carried out to study the effects of Quebracho tannins extract (QE) on fatty acid profile of rumen solid adherent bacteria (SAB) during the fermentation of diets supplemented with soybean or linseed oil, as sources of linoleic (LA; 18:2 n-6) and α- linolenic...

| description | An <em>in vitro</em> trial was carried out to study the effects of Quebracho tannins extract (QE) on fatty acid profile of rumen solid adherent bacteria (SAB) during the fermentation of diets supplemented with soybean or linseed oil, as sources of linoleic (LA; 18:2 n-6) and α- linolenic acid (α-LNA; 18:3 n-3), respectively. Two control diets were prepared using a basal mixture of grass hay [760 g/kg on dry matter (DM)], soybean meal (55 g/kg DM), barley meal (130 g/kg DM), vitamin mineral premix (20 g/kg DM) and 35 g/kg DM of soybean (SOC diet) or linseed oil (LOC diet) as lipid supplement. Other two diets (SOCT and LOCT) were obtained by integrating SOC and LOC with QE (49 g/kg DM). The results confirmed that Quebracho tannins may be an effective method for reducing in SAB the biohydrogenation of LA (17.3 <em>vs</em> 34.5 g/100 g of fatty acid in SOC and SOCT, respectively) and LNA (10.7 <em>vs</em> 21.4 g/100 g of fatty acid in LOC and LOCT, respectively), but not for increasing the rumen accumulation of <em>cis</em>9, <em>trans</em>11 18:2 (0.77 <em>vs</em> 0.32 g/100 g of fatty acid in SOC and SOCT, respectively; 0.51 <em>vs</em> 0.43 g/100 g of fatty acid in LOC and LOCT, respectively) and <em>trans</em>11 18:1 (6.15 <em>vs</em> 3.64 g/100 g of fatty acid in SOC and SOCT, respectively; 5.53 <em>vs</em> 4.47 g/100 g of fatty acid in LOC and LOCT, respectively). |
