Abstract: The invention relates to a feed and to a process for its production. According to the process, a fatty substance is converted to the form of a metal salt of a fatty acid or fatty acids, and is combined with a carrier such as a concentrated feed. In the salt form the salt is protected in such a way that it will not disturb the disintegration taking place in the rumen of a ruminant, but it is, nevertheless, exploitable by the digestive system of the animal. What is essential in the invention is that the metal salt is formed into a three-dimensional matrix so that a substantially liquid fat or fatty acids remain in the cavities of the matrix. In a matrix form such as this the fat is fluid, and it can be transferred and batched like a liquid. It is possible to use vegetable oils which contain unsaturated fats and fatty acids for the production of a feed, whereby the fats and fatty acids can be caused, by means of the protection, to pass through the digestive system of a ruminant to the milk produced.
