Abstract: The invention relates to a mixture for making a cooking-extruded extrudate, the mixture including an aqueous animal ensilage and a vegetable material, and—the aqueous animal ensilage including a water-soluble protein fraction, a water-insoluble protein fraction and fat;—the mixture including from 12.5% by weight or more of ensilage dry matter to 42% by weight or less of ensilage dry matter; and—the mixture including at least 15% by weight of water and less than 34% by weight of water. The invention also relates to a method of making a cooking-extruded extrudate from the mixture. The invention further relates to a use of the cooking-extruded extrudate.

Abstract: A rearing fodder of extruded fodder type, comprising proteins, fats and carbohydrates, for freshwater fish, wherein the fish is larger than 2 grams, and wherein the freshwater has a content of CO2 being above 5 milligrams/liter, wherein the fodder has an increased content of at least one of the minerals: phosphate (P), potassium (K), calcium (Ca), sodium (Na) and magnesium (Mg) beyond what exists naturally in the used protein raw materials, fat raw materials and carbohydrate raw materials, wherein the collective amount of minerals in the extruded fodder is at least 10%, on a dry substance basis, of the total weight of the fodder, and wherein one or more of the minerals phosphate (P), potassium (K), calcium (Ca), sodium (Na) and magnesium (Mg) is/are added beyond what exist in the used protein raw materials, fat raw materials and carbohydrate raw materials.
