Product Details
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 is the recommended shelf life and storage protocol for Vitamin C?
This product has a shelf life of 48 months. It must be stored in a dry, cool, and well-ventilated environment. Keep it protected from direct sunlight, moisture, and high temperatures to maintain its chemical stability.
5. What are the specific Vitamin C dosage requirements for aquatic species?
The recommended dosage based on L-Ascorbic Acid content is: Tilapia & Eel Fry require 300 mg/kg; Tilapia & Eel Fingerlings require 200 mg/kg; Grass Carp & Carp require 300–500 mg/kg; Catfish & Rainbow Trout require 100–150 mg/kg.
6. How can risks associated with incompatible feed ingredients like Copper Sulfate or Choline Chloride be mitigated?
For Copper sulfate, use coated copper or separate mixing to prevent pro-oxidant degradation. For Choline chloride (>60%), premix with dry carriers such as silica to prevent hygroscopic clumping. For Calcium carbonate, pre-acidify the premix to pH <5 to stop pH-induced oxidation.
