Short summary
Polyunsaturated fatty acids play an important role in a wide variety of physiological processes. They are produced by a series of chemical reactions. One of the enzymes converting such acids is a delta 6 desaturase encoded by the FADS2 gene. Therefore, we aimed to determine possible associations between the polymorphism in this gene and milk fatty acid composition in dairy cattle. An identified substitution could be used as a potential genetic marker for fatty acid composition in bovine milk.
