The composition of the feed does not contain salt, i.e. salt is not specifically added to the feed, the feed is not salted, but the ingredients used in the preparation of the feed have salt, including meat, in their chemical composition. So the feed has salts, but only from products used in the preparation of the feed, salt is not added as an extra. In the process of extrusion and gentle low-temperature heat treatment, evaporation of moisture from the ingredients (from the granules) occurs and in the process some crystals from microelements may form on the surface of the granules. Since the heat treatment of the granules is gentle, the crystals do not dissolve and do not burn.
