Glycinate Chelated Magnesium Feed Grade Amino Acid Glycine Chelate
Magnesium is an essential component of animal bone and dental structures, primarily functioning in concert with potassium and sodium to regulate neuromuscular excitability. Magnesium glycinate exhibits excellent bioavailability and serves as a premium magnesium source in animal nutrition. It partakes in energy metabolism, neuromuscular regulation, and enzymatic activity modulation, thereby aiding stress mitigation, mood stabilization, growth promotion, reproductive performance enhancement, and skeletal health improvement. Moreover, magnesium glycinate is recognized as GRAS (Generally Recognized As Safe) by the U.S. FDA and is listed in the EU EINECS inventory (No. 238‑852‑2). It complies with the EU Feed Additives Regulation (EC 1831/2003) regarding the use of chelated trace elements, ensuring robust international regulatory conformity.

Product Benefits
1） Stable Chelation, Preserves Nutrient Integrity
Glycine, a small‑molecule amino acid, forms a stable chelate with magnesium, effectively preventing deleterious interactions between magnesium and fats, vitamins, or other nutrients.
2） High Bioavailability
The magnesium‑glycinate chelate utilizes amino acid transport pathways, enhancing intestinal uptake efficiency compared to inorganic magnesium sources such as magnesium oxide or magnesium sulfate.
3） Safe and Environmentally Friendly
High bioavailability reduces excretion of trace elements, mitigating environmental impact.
Product efficacy
1） Stabilizes the central nervous system and alleviates stress responses.
2） Acts synergistically with calcium and phosphorus to support robust skeletal development.
3） Prevents magnesium‑deficiency disorders in animals, such as muscle spasms and postpartum paresis.
Product applications
1.Pigs
Dietary supplementation of 0.015 % to 0.03 % magnesium has been shown to significantly improve sow reproductive performance, shorten the weaning‑to‑estrus interval, and enhance piglet growth and health. Studies indicate that magnesium supplementation is particularly beneficial for high‑producing sows, especially as their body magnesium reserves decline with age, making dietary magnesium inclusion increasingly important.
2.Broilers
Inclusion of 3,000 ppm organic magnesium in broiler diets under heat‑stress and oxidized‑oil challenge conditions did not adversely affect growth performance, but it did markedly reduce the incidence of woody breast and white striping myopathies. Concurrently, meat water‑holding capacity was improved and muscle color quality enhanced. Additionally, antioxidant enzyme activities in both liver and plasma were significantly elevated, indicating strengthened antioxidative capacity.
3.Laying Hens
Research demonstrates that magnesium deficiency in laying hens leads to reduced feed intake, egg production, and hatchability, with the drop in hatchability closely linked to hypomagnesemia in the hen and decreased magnesium content within the egg. Supplementation to reach a dietary level of 355 ppm total magnesium (approximately 36 mg Mg per bird per day) effectively maintains high egg‑laying performance and hatchability, thereby boosting production efficiency.
4.Ruminants
Magnesium inclusion in ruminant rations substantially enhances ruminal cellulose digestion. Magnesium deficiency reduces both fiber digestibility and voluntary feed intake; restoration of adequate magnesium reverses these effects, improving digestive efficiency and feed consumption. Magnesium plays a critical role in supporting rumen microbial activity and fiber utilization.

5.Aqua Animals
Studies in Japanese seabass have shown that dietary supplementation with magnesium glycinate significantly enhances growth performance and feed conversion efficiency. It also promotes lipid deposition, modulates expression of fatty‑acid–metabolizing enzymes, and influences overall lipid metabolism, thereby improving both fish growth and fillet quality.
