Finely ground calcium carbonate, milled to 250 mesh — a fast-dissolving calcium source for premix and concentrate.
Coarse-granulated calcium carbonate for layer feed, where slower dissolution supports overnight eggshell calcification.

Feed-grade phosphorus and calcium supplement, granular form for even mixing.
