Copper Glycinate is an organic copper source formed by chelation between glycine and copper ions. Due to its high stability, good bioavailability and friendliness to animals and the environment, it has gradually replaced traditional inorganic copper (such as copper sulfate) in the feed industry in recent years and has become an important feed additive.
Product name: Glycine chelated copper
Molecular formula: C4H6CuN2O4
Molecular weight: 211.66
Appearance: blue powder, no agglomeration, fluidity
Promoting animal growth performance Copper glycinate can significantly improve the daily weight gain and feed conversion rate of piglets. Studies have shown that adding 60-125 mg/kg of copper glycinate can increase feed intake, improve digestibility, and stimulate growth hormone secretion, which is equivalent to high-dose copper sulfate, but the dosage is lower. For example, adding copper glycinate to the diet of weaned piglets can significantly increase the number of lactic acid bacteria in feces and inhibit Escherichia coli, thereby optimizing intestinal health. Improving the absorption and utilization of trace elements Copper glycinate reduces the antagonistic effect of copper ions and other divalent metals (such as zinc, iron, and calcium) through a chelated structure, improves the absorption rate of copper, and promotes the synergistic absorption of other trace elements14. For example, its moderate stability constant can avoid competing with other minerals for absorption sites in the digestive tract. Antibacterial and immunomodulatory Copper glycinate has a significant inhibitory effect on harmful bacteria such as Staphylococcus aureus and pathogenic Escherichia coli, while maintaining the balance of intestinal flora, increasing the proportion of probiotics (such as lactic acid bacteria), and reducing the rate of diarrhea. In addition, its antioxidant properties can reduce free radical damage and enhance the animal’s ability to resist stress. Environmental advantages Traditional high-dose inorganic copper (such as copper sulfate) tends to accumulate in animal feces, causing soil pollution. Copper glycinate has a high absorption rate, reduced excretion, and stable chemical properties, which can reduce the environmental copper load.
Advantages of Chelated Structure Copper glycinate uses amino acids as carriers and is directly absorbed through the intestinal amino acid transport system, avoiding gastrointestinal irritation caused by the dissociation of inorganic copper in gastric acid and improving bioavailability. Regulating intestinal microorganisms By inhibiting harmful bacteria (such as Escherichia coli) and promoting the proliferation of beneficial bacteria, the intestinal microecology is optimized and antibiotic dependence is reduced. Studies have shown that the addition of copper glycinate (60 mg/kg) can significantly increase the number of lactic acid bacteria in piglet feces. Promoting Nutritional Metabolism Copper, as a cofactor of multiple enzymes (such as superoxide dismutase and cytochrome oxidase), participates in physiological processes such as energy metabolism and heme synthesis. The efficient absorption of copper glycinate can ensure the normal functioning of these functions.
Additional dosage control Excessive addition may inhibit the growth of probiotics (e.g., the number of lactic acid bacteria decreases at 120 mg/kg). The recommended daily addition amount for piglets is 60-125 mg/kg, and for fattening pigs is 30-50 mg/kg. Applicable animal range Mainly used for pigs (especially weaned piglets), poultry and aquatic animals. In aquatic feed, due to its insoluble nature in water, it can reduce the loss of copper. Compatibility and stability Copper glycinate has better oxidation stability for vitamins and fats in feed than copper sulfate, and is suitable for use in conjunction with alternative antibiotics such as acidifiers and probiotics to reduce costs.
