| Various recent studies have indicated positive interactions between organic animal production and poly-unsaturated fatty acids, particularly CLA and omega-3. In this paper, we present the monitoring results of 15 organic farms concerning the rela-tionship between feeding practices and fatty acid pattern. The results indicate a strong negative effect of maize and grass silage and concentrate feeding on CLA levels in milk fat. On the other hand, feeding fresh grass has a positive effect. Omega-3 levels in milk fat seem less related to feed characteristics: similar relations to those with CLA seem to exist, but feed composition explains the variation in omega-3 levels only to a limited extent, while there is a large farm influence. This might be related to... |
