Feed Grade Calcium Propionate
Keeping feed stable during storage is not always easy, especially in hot and humid regions. Our feed grade calcium propionate is designed to help feed manufacturers reduce mold problems, protect feed quality, and maintain consistent performance from production to farm use.
Feed Grade Calcium Propionate
Compound feed stored in tropical warehouses can develop mold when humidity exceeds 70%, degrading protein and palatability. Feed grade calcium propionate releases propionic acid in feed particle moisture films to suppress mold, while adding measurable calcium to the ration.
Note: Strictly for animal nutrition. For bakery use, see food grade calcium propionate.

Why Feed Mills Choose Our Supply
- Dedicated Production: Manufactured on a separate line guaranteeing zero cross-contamination with food-grade batches.
- Targeted QC: Batch testing focused on assay, moisture, and heavy metals (Pb ≤ 10 mg/kg) aligned with livestock safety.
- Logistics Expertise: Bulk export experience to high-humidity regions with ocean-freight-optimized packaging.
Applications in Feed Industry
- Compound Feed & TMR: Suppresses mold in high-moisture rations (distillers grains, molasses) for poultry, swine, and ruminants.
- Vitamin & Mineral Premixes: Neutral pH prevents acid-catalyzed vitamin oxidation, ensuring potency during storage.
- Silage & Haylage: Stabilizes fermentation in chopped forage (60%-75% moisture) alongside formic acid, preventing aerobic spoilage during feed-out.
- Grain Storage: Protects maize and soybean meal in ambient warehouses or ocean transit from moisture-triggered mold.
Recommended Inclusion Rates (Reference)
- Compound Feed & TMR: 1.0 – 3.0 kg/ton (0.1% – 0.3%), adjusted based on ingredient moisture and storage duration.
- Silage & Haylage: 2.0 – 4.0 kg/ton of fresh forage. Often combined with formic acid for complementary pH control.
- High-Moisture Grain: 1.5 – 2.5 kg/ton for long-term ambient storage protection.
*Actual dosage should be determined based on substrate moisture, ambient temperature, and desired shelf life. Consult a livestock nutritionist for specific ration formulations.
Key Operational Advantages
- Storage Stability: 99.0% assay and controlled moisture ensure chemical stability during 6-month bulk silo storage.
- Premix Compatibility: Granular form resists segregation in pneumatic conveying, ensuring uniform distribution without hotspots.
- Silage Application: Powder form dissolves rapidly in plant tissue juice during compaction for even bunker coverage.
Storage, Handling & Packaging
- Packaging: 25 kg PP bags with PE liner, or jumbo bags. Powder ~16.5 MT/20ft FCL; granular up to 20 MT.
- Storage: Cool, dry area. Granular form resists caking better than powder in >70% humidity.
- Shelf Life: 24 months. Use dust mask and gloves.
Note: Calculate total acid load when combining with formic acid in silage to avoid depressing ruminant palatability.
Frequently Asked Questions
What is the difference between calcium and sodium propionate for feed?
Calcium propionate delivers the same mold inhibition but adds measurable calcium. It also maintains better physical stability in dry premixes where sodium salts absorb moisture. See our sodium propionate for alternatives.
How to choose between powder and granular?
Powder dissolves rapidly in silage juice. Granular resists dust during pneumatic conveying and automated batching. In >70% humidity, granular resists caking better.
How does moisture content affect efficacy?
It releases propionic acid in feed particle moisture films. Above 14% grain moisture or 65% ambient humidity, mold accelerates. Adjust addition rates to actual substrate moisture.
Can it replace propionic acid in silage?
It supplements but does not fully replace propionic acid. Propionic acid drops pH directly, while calcium propionate releases propionic acid without significant acidification. Both are often used together.
