dc.description.abstractFourteen Assaf ewes in mid lactation were used to examine the effect of the addition of a mixture of two extracts of condensed and hydrolysable tannins to a diet containing sunflower oil, on milk fatty acid (FA) profile. All sheep received a total mixed ration based on alfalfa hay and a concentrate (F:C 40:60), supplemented with 20 g of sunflower oil/kg dry matter (DM) plus 0 (Control) or 10 (TAN) g of tannins/kg DM. Milk FA profile was analysed on days 0, 3, 6, 12, 18, and 27 on treatments. Addition of tannins did not significantly alter the concentration of the major FA classes in milk (i. e., saturates, monounsaturates, and polyunsaturates), had very limited effects on the proportion of particular FA, and was not able to enhance milk VA and RA enrichment above that achieved with sunflower oil supplementation. Temporal changes in the milk FA composition were characterized by an increase in unsaturated FA with 18 carbons (mainly cis-9 and trans-11 18:1, but with no variation in the low levels of trans-10 18:1) and a concomitant reduction in most short and medium chain saturates (6:0 to 12:0 and 16:0; P<0.05) attributable to the presence of sunflower oil in the diet. The low dose, the type of tannins, or both, may have been responsible for the lack of significant changes in milk FA profile.es_ES
