Product Description
Feed-grade calcium propionate is an organic acid salt feed additive produced by reacting propionic acid and calcium carbonate. It primarily functions as a mold inhibitor and preservative in animal feed, as well as a calcium supplement, and we also widely use calcium propionate in the processing and storage of pig, poultry, and aquatic feeds.
In terms of mold prevention and preservation, the core mechanism of feed-grade calcium propionate is the release of free propionic acid, which penetrates the cell membranes of microorganisms and interferes with their metabolic enzyme activity, thereby inhibiting the growth and reproduction of molds, aerobic Bacillus, and various putrefactive bacteria. In hot and humid seasons or with high-moisture feeds (12%-15% moisture content), so adding feed-grade calcium propionate (recommended dosage 0.1%-0.5%) can significantly extend the safe storage period of the feed and reduce nutritional losses and animal health risks caused by mold growth.

Application Cases of Calcium Propionate
| Cases | Analysis of main causes | Solusions |
| The anti-mildew effect did not meet expectations. | ① Insufficient addition: Calculation error or failure to consider initial moisture content/high mold contamination of raw materials.② Uneven mixing (prone to spherical particles): Caused by short mixing time or poor equipment performance.③ Inappropriate application: Calcium propionate is effective against fungi, but ineffective against existing bacterial toxins.④ Harsh storage environment: High humidity exceeds the preservative’s effective range. | ① Scientific Calculation: Adjust the amount of calcium propionate added based on the season, raw material moisture content (>12%, require increased dosage), and storage period.② Optimized Process: Ensure thorough mixing, paying particular attention to spherical particles.③ Comprehensive Mold Prevention: Monitor raw material quality; severely moldy raw materials should be prohibited.④ Improved Storage of calcium propionate: Control warehouse temperature and humidity; prioritize the use of recycled materials. |
