Fatty acid composition of milk fat of Ukrainian mountain sheep under the higher level of sulfur and jodine in their diet
The data about the fatty acid composition of milk fat of Ukrainian mountain ewes under the higher level of sulfur and iodine in their diet were presented. It was shown ewe’s milk fat contains 48 fatty acids with length of chain C4 up C24 with pair and nonpair carbons and ramified fatty acids ― iso- and anteiso- and fatty acids of cys- and trans- configuration. Feeding up ewes by iodine (I group), iodine and sulfur (II group) in their diet accompanied by increasing of unsaturated fatty acids content on 5,40 % (I group) and 4,43 % (II group) in the milk fat. The increase of unsaturated fatty acids content is due to both monounsaturated and polyunsaturated fatty acids (oleic cys- 9 C18:1, vaccenic trans- 11 C18:1) and decrease of middle length chain fatty acids content ― lauric, myristic and palmitic.
