What it is
A calibrated coarse limestone grit with optimised particle size gradation — formulated to support mechanical digestion, gizzard development, and sustained overnight calcium release in layer and breeder poultry, where particle size is the primary variable governing calcium bioavailability and feed conversion efficiency.
What it does
- Supports gizzard grinding efficiency and mechanical digestion in poultry
- Delivers sustained, gradual calcium release — including overnight supply critical for layer performance
- Improves eggshell integrity, thickness, and hatchability in layer and breeder flocks
- Enhances feed conversion ratios through improved nutrient extraction
- Promotes digestive tract health and long-term flock productivity

FAQs
If you have questions about limestone products, specifications, or typical applications, the answers below address some of the most common topics. For anything more specific, our technical team is happy to help.
Why is particle size the defining variable in calcium performance for layer and breeder operations?
Coarse grit dissolves slowly — CaSure Grit's calibrated 0.5 – 4 mm gradation sustains calcium release through the night, precisely when laying hens are forming eggshells and fine powder simply cannot deliver.
How does CaSure Grit directly improve eggshell quality and hatchability outcomes?
Sustained, bioavailable calcium supply — enabled by segregated size bands and controlled top-cut — supports shell thickness, integrity, and hatchability consistency across layer and breeder flocks at production scale.
What operational advantage does CaSure Grit deliver beyond standard calcium supplementation?
Better digestion. Better conversion. CaSure Grit's coarse gradation drives gizzard development and mechanical grinding efficiency — improving nutrient extraction and long-term flock productivity from a single, calibrated input.
