Fatty acid profile and CLA content in milk from cows fed different soybean sources

Abstract

The soybean meal is the main protein source in the ruminant diets and the EU consumption is about 27 million t/year (Brookes, 2000). However, problems have been recently risen by the use of GM soybean and derivates in animal feeding. The GM soybeans can be incorporated in the animal feeds and/or diets, especially if the seed or derivates are imported from extra-UE countries. In addition, the use of soybean meal is forbidden by the regulation of the organic livestock farming and/or the production of some typical foods. To this purpose the use of non-GM soybean, produced and treated directly in the farm, could be encouraged in the animal feeding.......
