Calcium Carbonate (CaCO₃) is an essential mineral in animal feed, playing a crucial role in bone development, eggshell formation, and digestion. But how is this natural resource processed to ensure maximum benefits for livestock? Let’s explore its journey from limestone quarries to farms worldwide.
1. Selecting High-Purity Limestone for animal feed
The first step in producing feed-grade CaCO₃ is sourcing high-quality limestone. Not all limestone is suitable for animal consumption—only deposits with high CaCO₃ purity and low impurities (such as heavy metals or silica) are used. Key selection criteria for limestone:
-
High calcium content (usually above 95%)
-
Minimal impurities (iron, magnesium, silica, and lead)
-
Compliance with international feed safety standards
To ensure these standards, we carefully mine limestone from controlled quarries and test it before further process
2. Crushing and Grinding to the Right Particle Size
After extracing, limestone undergoes crushing and grinding to achieve the right particle size. Different livestock species require different forms of Calcium Carbonate:
-
Fine Powder (200-600 mesh) → Ideal for poultry feed, ensuring fast calcium absorption for eggshell production.
-
Granules (0.5-3mm) → For cattle and dairy farming, providing slow-release calcium for stronger bones and milk production.
-
Coarser Particles → Suitable for ruminants like goats and sheep, aiding in digestion and balancing pH levels in the stomach.
Advanced milling technology ensures uniform particle size, which improves feed formulation and nutrient absorption in animals.

3. Purification and Quality Control
Before CaCO₃ get approval for animal consumption, it undergoes multiple purification steps to remove unwanted elements. The purification process includes:
-
Screening for contaminants → Heavy metals, silica, and impurities are carefully removed.
-
Laboratory testing → Samples are tested to meet international feed-grade standards (such as FAMI-QS, GMP, and ISO 22000).
-
Moisture and flowability control → Ensuring CaCO₃ remains stable and non-clumping during storage and transportation.
This strict quality control process guarantees safety, digestibility, and optimal nutritional benefits.
4. Packaging and Global Distribution
Once processed and purified, Calcium Carbonate is packaged in bulk or customized bags to suit different animal feed formulations. The final product's uses:
-
Feed mills – Where CaCO₃ is blended with other nutrients.
-
Dairy farms – Used in direct supplementation for cows.
-
Poultry farms – Included in layer hen feed for eggshell strengthening.
-
Aquaculture facilities – Supports shell growth in shrimp and other aquatic species.
Calcium Carbonate from Vietnamese limestone quarries export to Bangladesh, South Korea, Japan, Singapore, Turkey, the U.S., Australia, Malaysia, and Indonesia.
5. Why Calcium Carbonate is a Must-Have in Animal Feed?
CaCO₃ isn't just a filler—it plays an active role in improving livestock health and productivity.
-
Strengthens Bones & Teeth – Prevents calcium deficiency in cattle, pigs, and poultry.
-
Improves Eggshell Quality – Ensures thicker, stronger eggshells in layer hens.
-
Regulates Digestion – Helps maintain a healthy stomach pH in ruminants.
-
Enhances Feed Efficiency – Ensures better nutrient absorption and feed conversion rates.
-
Prevents Acidosis in Dairy Cows – Helps balance stomach acidity, reducing rumen acidosis risk.
Conclusion
A Natural Solution for Livestock Nutrition
From limestone quarries to livestock nutrition, Calcium Carbonate is a game-changer in the feed industry. With advanced processing techniques, strict quality control, and optimized particle size, high-purity CaCO₃ ensures better health, higher productivity, and stronger yields for farmers worldwide.
