Propionic Acid Feed Grade Applications:
Feed-grade propionic acid primarily acts as a preservative for animal feed and grains, inhibiting mold, yeast, and bacterial growth to extend shelf life and improve feed quality.
- Mold & Bacteria Inhibition: Prevents spoilage in stored grains (corn, wheat, barley) and compound feeds, reducing losses.
- Silage Improvement: Enhances fermentation and aerobic stability, preserving forage quality.
- Liquid Feed & Water Treatment: Reduces bacteria in liquid feeds and livestock drinking water, promoting healthier animals.
- Nutrient Absorption: Aids digestion and nutrient uptake in livestock.
- Hay Preservation: Used to treat hay, ensuring it's safe and palatable for horses and other livestock.
