Coarse-granulated calcium carbonate for layer feed, where slower dissolution supports overnight eggshell calcification.
Sized to 2–3mm granules, this is the standard limestone grade for layer diets — the larger particle dissolves more slowly in the gizzard, supplying calcium through the night when eggshell is being formed.
