PowerCal is an ultra-fine ground calcium carbonate from young Coccolith deposits. The lime is very porous and has a high pH level. The product is a pure natural product.

The unique structure prevents the product from sticking to the cow. In comparison with other bedding materials, PowerCal has a high moisture-binding capacity. This prevents the surface from becoming slippery and also it doesn't harden when it dries again. PowerCal is very suitable for scattering in the cubicles of cattle in order to inhibit the growth of micro-organisms and bacteria.
