Selected candidate genes affecting milk fatty acids

Robert Kala, Eva Samková, Jindřich Čítek


Cow´s milk consisted of relatively high quantity of saturated fatty acids (about 70%), which are considered less beneficial health. The content of more desirable fatty acids is about 25% (monounsaturated) and 5% (polyunsaturated). The aim of this research was to find ways how to increase the content of mono- and polyunsaturated fatty acids in milk fat. One of the ways how to alter the content of fatty acids is the monitoring of candidate genes and their polymorphism. Therefore, the manuscript deals with selected candidate genes, particularly DGAT1, SCD1 and FASN, which are associated with fatty acid biosynthesis. The results suggest that observing of this issue could be helpful for improving the quality of milk fat.
