Vitamin B6 (including forms such as pyridoxine, pyridoxal, and pyridoxamine) is a key water-soluble vitamin in animal feed. As a coenzyme for over 100 enzymes in the body (especially transaminases and decarboxylases), it is primarily involved in the metabolism, transformation, and synthesis of proteins and amino acids, and is crucial for the efficient utilization of nitrogen. In animal husbandry, vitamin B6 can significantly promote the absorption and deposition of feed protein by animals, increase growth rate and lean meat ratio. Maintain healthy nervous system function (participate in neurotransmitter synthesis) and immune response (support antibody production); And it helps prevent nutritional anemia (participating in the synthesis of hemoglobin). Deficiency can lead to various metabolic disorders, with typical symptoms including growth arrest, abnormal excitement, convulsions and anemia in poultry. Pigs' loss of appetite, coarse and disheveled fur, movement disorders and decreased reproductive performance; Young ruminants may also experience growth retardation. Because the amount synthesized by animals themselves is extremely small and the demand increases under high-protein diets, stress or rapid growth conditions, it is necessary to provide sufficient supplementation in complete feed.
