Sažetak

Feed composition is one of the most influential factors affecting fatty acid profile of milk products. The aim of this study was to investigate the influence of linseed oil and linseed extrudate supplementation on fatty acid composition of goat prebiotic and probiotic yogurt drinks. Thirty six White Shorthaired dairy goats at the beginning of their third lactation period were divided into two experimental and one control group, each comprising twelve animals. Goats in the experimental groups were given either 55 mL/day of linseed oil or 120 g/day of linseed extrudate over a three week period. The results suggest that feed supplementation with linseed oil and linseed extrudate caused considerable changes in fatty acid profile of goat yoghurt drinks. The most important nutritional change which was observed was increased n-3 fatty acid content (P<0.001) and decreased saturated fatty acid content (P<0.001). α-linolenic acid was significantly elevated (P<0.001) in both groups (in particular in goats which feed was supplemented with linseed oil).
