Dietary intervention is a well-recognised approach to modifying milk yield and physicochemical characteristics. This study aimed to evaluate the effects of supplementing ewes' diet with tannin and/or linseed oil on the physicochemical characteristics and fatty acid profile of milk, as well as the antioxidant status of dairy ewes. The study involved 36 3-year-old lactating Moghani sheep randomly assigned to six treatment groups. Results demonstrated that tannin extract and linseed oil changed the fatty acid content of milk. In particular, unsaturated fatty acids and conjugated linoleic acid were increased by the treatments (P < 0.05). Generally, groups receiving tannin extracts and/or oil showed higher concentrations of unsaturated fatty acids in their milk, especially polyunsaturated fatty acids including C18:3n3, C20:2, C20:3n3, C20:4n6, CLA cis-9 trans-11, CLA trans-10 cis-12, C22:2 and total unsaturated fatty acids.
