Zur Fettsäurenzusammensetzung der Kuhmilch in Abhängigkeit von Weidehaltung sowie konventioneller oder ökologischer Wirtschaftsweise

Summary in the original language of the document

The objective of this study was to estimate the influence of different husbandry systems (organic vs. conventional) and fodder components (pasture vs. conserved feed (esp. corn silage)) on the composition of fatty acids in milk fat during the grazing period. Therefore, the fatty acid composition of herd milk of 27 bavarian dairy farms (conventional without pasture (n=9), conventional with pasture (n=9), organic with pasture (n=9)) was analyzed. The contents of omega-3-fatty acid and of conjugated linoleic acid (CLA) of milk from organic dairy farms with pasture was significant higher (1,42 % resp. 2,17 %) compared to the conventional farms with pasture (0,96 % resp. 1,37 %). The conventional dairy farms without pasture showed the lowest level (0,59 % resp. 0,69 %).
