Fatty acid profile of milk fat of different breeds of cows of the Voronezh region

The article examines the results of gas chromatographic analysis of the profile of fatty acids in milk fat from cows of different breeds. The changes in the fatty acid profile of milk fat of individual cows of red-and-white, black-and-white, Holstein and Jersey breeds bred in the Voronezh region are analyzed. Correlations of the fatty acid profile of milk fat of Jersey and Holstein cow breeds with a median profile, as well as a correlation between the content of fatty acids C10:0 and C12:0; C12:0 and C14:0 were found. The variability of the fatty acid profile in the milk of cows of different breeds and the presence of natural correlations in the ratios of fatty acids depending on the sum of genotypic and phenotypic factors were confirmed. Algorithms for identifying these factors using gas chromatographic data were proposed.
