Frequently Asked Questions (FAQs)
1. What are the primary functions of Vitamin C in animal feed?
L-Ascorbic Acid (Vitamin C) is vital for antioxidant protection, collagen synthesis, and immune system enhancement in livestock. It reduces oxidative stress in poultry during heat waves, improves wound healing in swine, and supports iron absorption in ruminants. Particularly critical for species lacking endogenous synthesis (e.g., poultry and fish).
2. How stable is L-Ascorbic Acid during feed processing?
Heat Sensitivity: Loses 20–30% activity after pelleting at 80°C for 2 minutes. Use coated forms (e.g., ethyl cellulose) for high-heat processing.
pH Stability: Optimal in pH 3–5. Rapid oxidation occurs in neutral/alkaline conditions (pH >6.5) – stabilize with antioxidants (e.g., BHT 0.1%).
pH Stability: Optimal in pH 3–5. Rapid oxidation occurs in neutral/alkaline conditions (pH >6.5) – stabilize with antioxidants (e.g., BHT 0.1%).
3. Can Vitamin C be mixed with minerals or other vitamins?
Compatible: Vitamin E (synergistic antioxidant effect) and Iron proteinate (enhances iron absorption).
Incompatible: Copper sulfate (>50 ppm) accelerates oxidation (pro-oxidant effect), and Sodium bicarbonate (alkaline premixes) causes pH-induced degradation.
Incompatible: Copper sulfate (>50 ppm) accelerates oxidation (pro-oxidant effect), and Sodium bicarbonate (alkaline premixes) causes pH-induced degradation.
4. What are the recommended storage conditions for this product?
