The aim of the study was to evaluate the effect of diet containing a supplemental mixture with alternative components suitable for organic herds on the yield and composition of milk and the fatty acid profile. The on-farm experiment was carried out on 12 dairy cows (mean lactation 2.3, on average 116 days in milk) that were divided into 2 groups. During the experiment cows were fed on a diet based on maize silage (30 kg/d), lucerne hay (3 kg/d) and supplemental mixture (8 kg/d, all as fed basis). The control group (C) was fed a control supplemental mixture, while the experimental group (E) was fed a supplemental mixture that contained rapeseed and sunflower components. The experiment was carried out in the form of a cross-over design and was divided into 2 periods of 14 days (a 7-d preliminary period and a 7-d experimental period). The total content of SFA was higher in C in comparison to E (P
