Abstract

This paper presents the results of an analysis of the composition of sheep milk fatty acids. Milk from Olkuska sheep, Polish mountain sheep, and crossbreeds of Polish mountain sheep and Friesian sheep (75% x 25%) was examined. The fatty acid profiles were analysed according to the month of lactation. Significant differences in fatty acid composition were observed for each breed. In the third and fourth month of lactation, in the milk of crossbreeds and Polish mountain sheep, respectively, saturated fatty acid content significantly decreased while the unsaturated and short-chain saturated fatty acid content increased. In the milk of Olkuska sheep, the content of short-chain saturated fatty acids and saturated fatty acids in the first and third months of lactation was significantly higher, while the content of oleic acid, mono- and polyunsaturated fatty acids was significantly lower than in the second and fourth months. It was also observed that the fatty acid profile of sheep's milk in the first two months of lactation was similar.
