| Title : | THE INFLUENCE OF OIL ADDITION ON THE FATTY ACID COMPOSITION OF SHEEP'S MILK DURING LACTATION |
| Abstract : | The aim of this study was to determine the impact of plant sources of fat in food for sheep on the fatty acid composition of milk samples obtained from 210 sheep (herd of pure Pramenka and a herd of crossbred sheep) in the area of the Una Sana Canton. The studies were conducted in three periods: winter, spring and summer, and the herd is divided into experimental and control groups of sheep. Extruded flax seed has been added to nutrition in experimental group of sheep in every period of research in the amount of 3.5%. The total content of saturated fatty acids was the highest during the summer with the experimental group (70.75%), which plant sources of fat were added to. The most common saturated fatty acids in the analyzed samples of milk were: palmitic, myristic, stearic and lauric, whose values varied depending on the treatment of nutrition and research period. The differences found in the content of saturated fatty acids between the period of investigation of milk sample of experimental and the control group showed statistically very highly significant effect (p<0.001). The content of unsaturated fatty acids was the highest during the summer in the control group of sheep (32.00%). Of monounsaturated fatty acids mostly consisted of oleic during the summer period (25.60%) in the milk of the control group. Of polyunsaturated fatty acids, linoleic acid (3.6%) in the milk of control and α-linolenic (1.90%) of milk experimental group of sheep were the most prevalent in the winter. The lowest ratio of omega-6/omega-3 fatty acids in sheep's milk was achieved in the period of feeding sheep with old grass (July), 1.46% in the milk of the experimental group of sheep that were fed with concentrates in which omega-3 preparations were added. |
