The aim of this study was to determine the effects of cow breed on the changing fatty acid composition of cow milk. A total of 105 cow milk samples were collected in November 2008. Gas Chromatography (GC) was used to determine the fatty acid composition of milk for Holstein, Simmental and Brown Swiss cow breeds. The milk fat saturated fatty acids (SFAs) concentration from the milk of Brown Swiss cows (70.19 %) was higher than that from Simmental (66.28 %) and Holstein (67.37 %) cows. The amount of mono unsaturated fatty acids (MUFAs) ranged from 28.53 (Brown Swiss) to 29.61 (Holstein) %. The biggest difference in poly unsaturated fatty acids (PUFAs) was between Simmental (2.74 %) and Brown Swiss (3.21 %). The concentration of conjugated linoleic acid (CLA) in Simmental (0.30 %) was higher in milk fat than the Holstein (0.28 %) and Brown Swiss (0.24 %). These data showed that there are the significant differences (P<0.05) in the fatty acid composition of milk from different cow breeds.
