Abstract
The present invention discloses a method for obtaining feed pellets. The method includes the addition of active ingredients to feed pellets after the pellets have been extruded. The method further includes the addition of a solution or suspension of the desired feed or ingredient in a water or oil phase to the pellets under reduced pressure and subsequently increasing the pressure. The method results in pellets with a high degree of loading and in which the active ingredients are homogeneously distributed.
