Glycine chelates of trace elements, such as glycine chelated iron, zinc, manganese, copper, etc., serve several functions and have various applications in animal nutrition. Here are their functions and applications:

1. Nutrient Absorption: Glycine chelates of trace elements enhance the bioavailability and absorption of essential minerals in the gastrointestinal tract of animals. Chelation involves the binding of trace elements to glycine molecules, forming stable complexes that are more readily absorbed by the intestinal lining compared to inorganic mineral salts. This results in improved utilization of minerals by animals for various metabolic processes.

2. Growth and Development: Supplementing animal feeds with glycine chelates of trace elements supports optimal growth, development, and performance in livestock, poultry, and other animals. Essential minerals such as iron, zinc, manganese, and copper play key roles in numerous physiological functions, including enzyme activity, protein synthesis, bone formation, immune function, and reproduction. Adequate levels of these minerals are crucial for promoting healthy growth and productivity in animals.

3. Prevention of Deficiency: Glycine chelates of trace elements help prevent deficiencies of essential minerals in animals, which can lead to various health issues such as impaired growth, reduced feed efficiency, compromised immune function, and reproductive problems. Chelated minerals are more efficiently absorbed and utilized by animals compared to inorganic mineral sources, reducing the risk of mineral deficiencies and associated performance losses.

4. Immune Function: Trace elements play a vital role in supporting immune function and disease resistance in animals. Glycine chelates of trace elements, particularly zinc, copper, and manganese, are involved in the synthesis of antioxidants, enzymes, and proteins that contribute to immune system function and defense against pathogens. Supplementing animal diets with chelated minerals helps maintain optimal immune function and enhance disease resistance in livestock and poultry.

5. Reproductive Health: Adequate levels of trace elements are essential for normal reproductive development, fertility, and reproductive performance in breeding animals. Glycine chelates of trace elements support reproductive health by ensuring proper hormone synthesis, gamete production, embryo development, and reproductive tract function. Optimal mineral nutrition is critical for maximizing breeding success and maintaining herd/flock productivity.

6. Stability and Compatibility: Glycine chelates of trace elements exhibit improved stability and compatibility in animal feed formulations compared to inorganic mineral salts. Chelated minerals are less prone to interactions with other feed ingredients, degradation, and nutrient antagonisms, ensuring their efficacy and reliability in meeting the nutritional needs of animals.

7. Environmental Considerations: Glycine chelates of trace elements offer environmental benefits by minimizing mineral excretion and reducing the risk of environmental pollution associated with excess mineral supplementation. Chelated minerals are more efficiently absorbed and utilized by animals, resulting in reduced excretion of mineral residues in manure and decreased environmental impact.

In summary, glycine chelates of trace elements serve as effective nutritional supplements in animal nutrition, providing enhanced bioavailability and utilization of essential minerals for promoting growth, development, immune function, and reproductive health in livestock, poultry, and other animals. Their applications extend to various animal species and production systems, contributing to overall animal health, welfare, and productivity.
