Calcium Propionate

Niaproof® Calcium Propionate

To prevent mold growth in various animal feed & agricultural applications (such as corn and grain) we offer Calcium Propionate*. The use of Calcium Propionate as mold inhibitor gives direct savings by maintaining the nutritive value and elongating the period the feed products can be used. Calcium Propionate also prevents the formation of mycotoxins (poisons produced by fungi) which could otherwise cause mycosis or mycotoxicosis infections in the digestive tract or respiratory system of broilers, turkey or laying flocks.

The dosage in which Calcium Propionate is used in feed applications depends on the water content/activity of the product, the initial bacterial/mold contamination, the storage temperature, the method of storage (anaerobic or aerobic) and the desired storage period. Typical dosages range from 1 to 3 kg/ton or 2 to 6 pounds/ton.
