Frequently Asked Questions
What makes this water-dispersible Vitamin D₃ superior to oil-based forms?
This microencapsulated Vitamin D₃ features nano-emulsification technology, enabling:
- Uniform dispersion: Stable in liquid feed systems (pH 3–8) without sedimentation.
- Enhanced bioavailability: 40% higher absorption in poultry vs. traditional D₃.
- Heat resistance: Retains 95% potency after steam conditioning at 90°C for 5 minutes.
How does the microparticle technology improve stability?
- Oxidation Resistance: 80% slower degradation vs. uncoated D₃ due to antioxidant-loaded coating (BHT + ascorbyl palmitate).
- Light Stability: Withstands UV exposure for 72 hours (vs. 8 hours for standard D₃).
Is it compatible with acidifiers, minerals, or liquid antibiotics?
- Compatible: Citric acid (pH 3–4) enhances dispersion stability. Zinc sulfate and Choline chloride show no interaction in liquid premixes.
- Incompatible: Potassium sorbate (>0.2%) disrupts the emulsification matrix. Oxytetracycline liquid forms chelate calcium in D₃ carriers.
What are the recommended storage conditions and shelf life?
The product should be stored in a cool, dry, and light-proof environment at a recommended temperature of ≤25°C. Keep the packaging tightly sealed to avoid contamination or moisture. The shelf life is 12 months when stored properly.
What is the recommended dosage for livestock and poultry?
The recommended dosages based on Vitamin D₃ content are:
- Swine: 150–500 IU/kg of feed
- Chickens: 400–2,000 IU/kg
- Ducks/Geese: 500–800 IU/kg
- Cattle: 275–450 IU/kg
- Sheep: 150–500 IU/kg
- Aquatic Species: 500–2,000 IU/kg
Which substances should be avoided to prevent compatibility risks?
Avoid mixing with Sodium benzoate (>0.5%) to prevent emulsion breakdown, high-salinity water (>3% NaCl) which causes microparticle aggregation, quaternary ammonium disinfectants due to charge interference, and ethanol (>5% in liquid) which dissolves the coating.
