ABSTRACT
Fish meal and pea meal in combination with cereals were formulated to be isonitrogeneous
and isoenergetic (NEL) and compared at high (HC) and low concentrate level (LC) in a continuous
production experiment with dairy cows in organic farming. Fish meal resulted in significantly higher
milk yield (kg) with a lower fat concentration (HC) compared to pea meal. The proportions of oleic
acid, vaccenic acid, CLA (LC), DHA, and total long-chain unsaturated fatty acids were significantly
higher, and the n-6/n-3 ratio was significantly lower (HC) in milk fat produced on fish meal compared
with pea meal. The sensoric quality of milk was not affected.
