Feed grade calcium carbonate is the most cost-effective calcium source in animal nutrition, and purity matters because it goes into the food chain. ELT (Egyptian Limestone Tiles) is a leading Egyptian supplier of feed grade calcium carbonate, milled from high-purity white limestone and exported factory-direct to feed mills and premix producers worldwide.

As one of the leading marble suppliers in Egypt, ELT also supplies Egyptian marble, Egyptian granite and Egyptian limestone tiles factory-direct, alongside its industrial calcium carbonate and limestone range.
What is feed grade calcium carbonate?
Feed grade calcium carbonate is finely ground natural limestone (CaCO₃) refined to meet the purity limits required for animal feed. It typically provides around 38% elemental calcium, the mineral most needed for bone development, eggshell formation and overall metabolism. Because it is natural, inexpensive and highly bioavailable, it is the standard calcium carrier in poultry, cattle, swine, aquaculture and pet feed, as well as in mineral premixes and licks.
Why purity and particle size matter
For feed, the key specs are high CaCO₃ purity, controlled heavy-metal limits (lead, arsenic, mercury), low moisture, and a consistent particle size. Layer poultry, for example, benefits from a blend of fine and coarse particles to balance immediate and slow calcium release for strong eggshells. ELT supplies Egyptian calcium carbonate ground to defined feed specifications, with each batch tested and documented so nutritionists can formulate with confidence.
Applications in animal nutrition
Feed grade calcium carbonate goes into poultry feed (broilers and layers), ruminant and dairy rations, swine and aquaculture feed, pet food, and free-choice mineral supplements. The same Egyptian limestone is also used as a limestone flux and as an industrial filler, but feed grades are produced and handled to tighter purity controls. Calcium carbonate’s role as a dietary calcium source is summarised in the mineral overview on Wikipedia.
Quality and traceability
Anything entering the feed chain has to be safe and consistent. As a quarry-to-mill producer, ELT controls purity, whiteness and particle size from the source, screens for heavy metals, and ships a certificate of analysis with every order. That traceability is essential for feed mills and premix plants that must meet their own regulatory and customer requirements.
Pricing, MOQ and export from Egypt
Sourced factory-direct, Egyptian feed grade calcium carbonate is highly competitive for bulk-bag and full-container volumes, with pricing set by purity, fineness and packaging. Minimum orders typically start at one 20-foot container, and ELT loads and documents shipments from Cairo to Europe, the Gulf, Africa, Asia and the Americas. Request a sample and a specification sheet to confirm fit for your formulation.
Coarse vs fine grades for layers
Egg-laying hens are a special case. Layers need a steady calcium supply overnight to build strong shells, so nutritionists often combine fine calcium carbonate for fast absorption with coarse limestone grit that dissolves slowly in the gizzard. Getting that ratio right reduces cracked eggs and improves shell quality. ELT can supply both fine feed grade calcium carbonate and coarser particle fractions, so feed mills and premix producers can build the exact release profile their flocks need.

Frequently asked questions
What is feed grade calcium carbonate used for?
Feed grade calcium carbonate is used as the main calcium source in animal feed for poultry, cattle, swine, aquaculture and pets, and in mineral premixes. It supports bone development and eggshell formation, providing around 38% elemental calcium in a natural, inexpensive and highly bioavailable form.
How much calcium does feed grade calcium carbonate contain?
Feed grade calcium carbonate contains roughly 38% elemental calcium by weight, derived from high-purity natural limestone. ELT mills it to defined feed specifications with controlled purity, heavy-metal limits and particle size, and provides a certificate of analysis with each shipment.
