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 and shelf life for Vitamin C?
Store in a dry, cool, and well-ventilated environment, protected from direct sunlight. Avoid exposure to moisture or high temperatures. The product has a shelf life of 48 months when stored properly under these conditions.
5. What is the recommended dosage of Vitamin C for swine, poultry, and cattle?
Based on L-Ascorbic Acid content, the recommended dosages are: Swine (150–300 mg/kg), Poultry (50–200 mg/kg), and Cattle (125–500 mg/kg). Dosages can be adjusted according to veterinary guidance or specific production needs.
6. How does the dosage of Vitamin C vary for aquatic species?
For aquatic species, the recommended dosages are: Tilapia & Eel Fry (300 mg/kg), Tilapia & Eel Fingerlings (200 mg/kg), Grass Carp & Carp (300–500 mg/kg), Catfish & Rainbow Trout (100–150 mg/kg), and Frogs (100–150 mg/kg).
