Sheep breeding on the mountain pastures of Bosnia and Herzegovina is a tradition inherited from the ancestors. Indigenous sheep breeds are widespread and well-adapted to harsh mountain farming conditions. Each year, after weaning, the sheep start grazing in the lowlands, then gradually moving to mountain pastures. Grazing positively affects the composition of fatty acids in sheep milk, with increased availability of polyunsaturated fatty acids in grass, and subsequently in milk. Consequently, this work aimed to study the profile of fatty acids in sheep milk during grazing in two geographical areas (Livanjsko polje and Vlašić Mountain). Milk was sampled from a total of 115 Pramenka sheep at two different pasture locations that differed in altitude: the location of pastures of Livanjsko Polje at an altitude of 700 - 750 m.a.s.l., mountain pastures of the Vlašić Mountain at an altitude of 1260 to 1280 m.a.s.l. Sheep milk samples were gathered during the grazing season from June to September and were analyzed by gas chromatography in the "As Vitas" laboratory of the Oslo Innovation Centre, Norway. The content of fatty acids in sheep's milk in this study showed a tendency to vary, with a relatively high content of saturated fatty acids. Milk samples from the Vlašić Mountain contained more polyunsaturated fatty acids than milk from the Livno area and a more favorable ratio of saturated to polyunsaturated fatty acids. Milk samples from both study areas contained an almost ideal ratio of n-6/n-3 fatty acids. The concentration of most bioactive fatty acids was higher in sheep's milk from the Vlašić Mountain area. Therefore, we can conclude that the altitude can influence the fatty acid profile of sheep milk. [ABSTRACT FROM AUTHOR] |
