Vitamin C (ascorbic acid) is an important water-soluble antioxidant and coenzyme factor in animals. Although most animals can synthesize it themselves, in the high-stress environment of modern intensive farming, its endogenous synthesis is often insufficient to meet the demand. The core role of adding vitamin C to feed lies in:Powerful antioxidantIt can effectively eliminate free radicals, alleviate oxidative damage to the body caused by heat stress, transport stress, etc., and maintain cell integrity.Significantly enhance immunityBy promoting the function of white blood cells and antibody production, it enhances the animal's resistance to diseases.Promote the synthesis of collagenIt is crucial for maintaining the health and repair of the skin, bones, blood vessels and connective tissues. Meanwhile, it can alsoImprove the absorption of ironPrevent anemia and to a certain extentImprove meat quality(Such as reducing the occurrence of PSE meat). For species that cannot synthesize vitamin C on their own (such as fish, some birds like Passeriformes, as well as primates, guinea pigs, etc.), feed supplementation is absolutely necessary. Therefore, when animals are facing rapid growth, harsh environments, disease challenges or special physiological stages (such as the breeding period), adding extra vitamin C to feed or drinking water has become an important nutritional management measure to ensure animal health and stabilize production performance.
