CaSure Grit

CaSure Grit is precisely sized limestone grit engineered for poultry feeds. With ~38% elemental calcium, it enhances gizzard function, digestion efficiency and eggshell formation. Uniform coarse particles ensure even blending in layer and breeder rations. Carefully controlled sizing supports sustained calcium release throughout the laying cycle, promoting healthier flocks and improved performance.

FAQs

Which birds and operations use CaSure Grit?
CaSure Grit is ideal for layers and breeders and mature poultry in commercial flocks, as well as small and medium farms. It also suits other birds like turkeys and ducks that require grit for digestion and sustained calcium release.
How does CaSure Grit support digestion and feed blending?
The uniform coarse particles stimulate the gizzard’s grinding action, improving feed breakdown, nutrient absorption and delivering available digestible calcium. They also blend easily with other feed components, ensuring consistent distribution and reliable calcium intake in every ration.
