a granular feed nutrient supplement is formed by pelletizing a mixture of minerals , vitamins and other nutrients along with a carrier such as cornmeal or the like and optionally a lubricant such as fat and / or a binder . the pellets are rolled to a desired size and combined with bulk feed . the size of the formed granules are maintained close to the average particle size of the bulk feed thereby ensuring that the granules remain suspended in the feed and do not separate . preferably the density of the granules is close to the density of the feed .
