Within the last years the nutritional value of food has become an important quality factor for consumers. In this context, the fat content and the fatty acid profile of food is often discussed. It is proven that certain fatty acids (omega-3, PUFA, CLA) have a positive impact on human health. These fatty acids can not be synthesized by the human body, but have to be consumed by food.
Several studies have proven that dairy cow feeding (forage, concentrates, feed additives) had a major impact on milk fatty acid profile. Meat and milk, which is produced in gras based production sytsems has a considerably higher content of valuable fatty acids compared to intensive systems based an high contentrate and maize silage amounts.
In Austria, hardly any studies on fatty acids of milk have been published. The results of the present study support Austrian dairy companies to advertise the fatty acid profile of Austrian milk particularly at the international market. Moreover, the project provides information for consumers and helps to transport the value of extensive, low input milk production system form farmer to consumer.
In the present project, milk from about 10 Austrian Alpine pastures, a continuous grazing farm (organic farm Moarhof of AREC Raumberg-Gumpenstein) and an intensive dairy cow herd (conventional farm of AREC Raumberg-Gumpenstein) is analysed for its fatty acid profile. Furthermore retail milk from Austrian supermarkets is analysed for fatty acids. Main emphasis of fatty acids analyses are the unsaturated fatty acids (omega-3, omega-6, CLA poly unsaturated fatty acids).
