Frequently Asked Questions
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.
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.
Incompatible Sulfonamides (e.g., sulfamethazine) – competitive inhibition of absorption. High-dose zinc (>500 ppm) – chelation in acidic conditions.
4. What are the storage requirements and shelf life of Folic Acid?
Folic Acid should be stored in a dry, cool, and well-ventilated environment away from direct sunlight and moisture. When stored properly in its original multi-layer sealed packaging (net weight 25 kg/drum), it has a shelf life of 24 months.
5. What is the recommended dosage of Folic Acid for swine and poultry?
The application involves directly adding Folic Acid to feed and mixing thoroughly. For poultry, the dosage is 0.5–1.5 mg/kg of complete feed. For swine, the dosage is 1.0–2.0 mg/kg, which should be increased to 3 mg/kg for sows during gestation.
6. How does Folic Acid interact with acidifiers and alkaline binders?
Folic Acid is compatible with acidifiers like citric acid and phosphoric acid, which stabilize it in acidic premixes (pH 5–6). However, it is incompatible with alkaline binders (such as limestone) because they cause pH-induced degradation. The mitigation strategy is to pre-mix Folic Acid with acidifiers to target a safe pH of 5–6.
