The aim of this study was to evaluate effects of three dairy cow groups consuming different grass diets (Diet A comprising of 20% grass, Diet B comprising of 50% grass and 100% grazed grass-G) on cow milk proximate and fatty acid (FA) com-position. The first principal component (PC1) accounted for 55.1%, and the second (PC2) accounted for 19.5% of the variance. The score values for PC1 and PC2 of the FAs show that milk fat from grass (MF G) was characterized by high C6:0, C8:0 and C14:0 con-tents. Milk from Diet A (MF A) was characterized by a higher content of C16:0. Milk from Diet B (MF B) was characterized by higher contents of C18:1n-9 and C18:2n-6 than milk from Diet A. The most favorable FA composition was in milk from Diet B, comprising 50% grass. The least favorable FA composition was in milk from Diet A, comprising 20% grass and in milk from 100% grazed grass.However, more testing is needed to bring a conclusion which food for dairy cows is the best
