PHOSSURE 12 is a phosphate-trace mineral concentrate, which contains the essential trace minerals in the correct ratio to phosphorus. PHOSURE 12 also has the unique characteristic that it is weather resistant. This means that the product will not be damaged by rain. When it rains, a hard crust is formed on top of the product. After the rain, animals quickly learn to break the crust & continue to eat the dry, undamaged lick underneath. PHOSSURE 12 is produced by blending mono dicalcium phosphate, spray dried molasses by-product, feed lime & specific amounts of trace minerals. The spray dried molasses by-product improves palatability & ensures water resistance.
