Abstract

The purpose. To study fatty acid content of butter oil of ewes of Ukrainian gornokarpatska breed, growing in different zones of Carpathians, in particular in lowlands and foothill. Methods. Biochemical, statistical. General lipids from milk were extracted using Folch method. For deriving methylated ethers of fatty acids they methylated using method of straight interesterification at availability of accelerant. Results. In butter oil of ewes of Ukrainian gornokarpatska breed they detected 42 fatty acids with chain length beginning from C4 up to C24 among which there were acids with twin and unpaired amount of carbon, and also branchy iso- and anteiso-acids and acids with cis-configuration and trans-forms. It was shown that conditions of growing ewes essentially influenced quantitative and quality fatty acid content of butter oil. That was connected with different character of their feeding which in its turn influenced direction of fermentation processes in a rumen of an animal. Conclusions. Fat-acid content ofmilk of ewes grown in different conditions had essential differences depending on definite factors. Among them the most essential were conditions of growing ewes and character of their feeding which factors influenced direction of fermentation processes in a rumen, level of dairy productivity and biological value of milk.
