摘要:
The present invention relates to fish feed pellets containing up to 55% by weight of lipids and a method of making said pellets. The pellets contain lipid, the major part of which, being liquid at ambient temperature and comprising oils of marine, animal and/or vegetable origin, and a minor part of lipids having high melting points 99.9-95.5% by weight of the lipids being liquid at ambient temperature are present in the bulk of the pellets having a top coating constituting 0.1-4.5% by weight of the total lipid content and consisting of 100-17% by weigth of a) glyceride or b) free fatty acids or c) crude palm oil or mixtures of a), b) and c) and where the components a, b and c all have high melting points, and 0-83% by weight of lipids being liquid at ambient temperature. The top coating consitutes preferably 0.5-1.5% by weight of total lipid content. The method comprises forming porous pellets by extrusion of commonly used feed components and then exposing said pellets to the lipid being liquid at ambient temperature until the pellets are saturated to a degree of 99.9-95.5% by said liquid. The pellets are then cooled and treated with said active components a, b and/or c, which can be mixed with lipid being liquid at ambient temperature, until the pellets get a top coating constituting 0.1-4.5% by weight of the total lipid content of the pellets.
