Product Details
FAQs
1. What are the primary functions of Folic Acid in animal feed?
Folic Acid (Vitamin B9) is essential for DNA synthesis, red blood cell formation, and amino acid metabolism in livestock. It prevents megaloblastic anemia in poultry, supports reproductive performance in swine, and enhances growth rates in young ruminants. Its role in methylation processes also improves overall metabolic efficiency.
2. How stable is Folic Acid under feed processing conditions?
Heat Sensitivity: Retains 85% activity after pelleting at 75°C for 1 minute. Prolonged exposure >80°C requires protective coatings.
pH Stability: Optimal in pH 5–7. Rapid degradation in alkaline environments (pH >8) – stabilize with acidulants (e.g., citric acid 0.3%).
Warning: Light-sensitive – use UV-blocking packaging and avoid fluorescent lighting during mixing.
3. Can Folic Acid be combined with minerals or other vitamins?
Compatible:
- Vitamin B12 (Cobalamin) – synergistic effect on red blood cell production.
- Zinc oxide, Iron proteinate (in acidic premixes).
Incompatible:
- Sulfonamides (e.g., sulfamethazine) – competitive inhibition of absorption.
- High-dose zinc (>500 ppm) – chelation in acidic conditions.
4. What are the recommended storage conditions and shelf life for Vitamin B9?
Store in a dry, cool, and well-ventilated environment. Avoid direct sunlight and moisture. The shelf life is 24 months when stored under proper conditions in its original net weight 25 kg/drum (multi-layer sealed packaging).
5. What is the recommended dosage of Folic Acid for swine and poultry?
Poultry: 0.5–1.5 mg/kg of complete feed.
Swine: 1.0–2.0 mg/kg (increase to 3 mg/kg for sows during gestation).
Ruminants: 2–4 mg/kg (calves and high-yield dairy cows).
Note: Directly add to feed and mix thoroughly, following specific production requirements or veterinary guidelines.
6. What compatibility guidelines should be followed for Folic Acid with feed additives?
Vitamins & Acidifiers: Compatible with B12, B6, and acidifiers (citric or phosphoric acid) which stabilize Folic Acid at pH 5–6. Add B9 after B6 in the mixing sequence.
Incompatibilities to Mitigate: Avoid mixing directly with alkaline binders like limestone (pre-mix with acidifiers instead), iron sulfate >400 ppm (use organic iron), or trimethoprim (administer 6 hours apart). Avoid liquid systems with ethanol due to solubility conflict.
