The article presents materials on the identification of milk fatty-acid composition of Holstein cows in farm of “Rza – Asyl tulik” in Kyzylorda region. The materials researched on gas chromatograph Shimadzu GC-2010 Plus with a flame ionization detector at the Kazakh-Japanese Innovation Center. The paper contains information about study milk lipids of the fatty acid composition of Holstein cows in the spring season. Also, the data of fatty acids depending on the breed of dairy cattle during the year. According to results, sum of polyunsaturated fatty acids commonly belongs to the cows of the group I – 3,12%, 2,86% – the cows of group II. A favorable ratio of the content of unsaturated fatty acids was obtained in milk fat in cows of the experimental group II. The content of saturated fatty acids, more in milk fat of cows of group II, and oil acid which human body mainly get from milk, is higher in milk fat of cows group II.
Key words: fatty acid composition, gas chromatography, milk, oil, Holstein breed.
