Chel means CLAW in Greek. The Mineral needs a support to CLAW itself. This support is provided by Amino Acids and this organic support is called LIGAND in chemistry. Amino Acids have a very low molecular weight and can be absorbed easily through the walls of the intestine and hence are most preferred ligands for chelation.
It is proved by studies that Amino Acids are ideal Organic Carrier (ligands) for Minerals. The Chelated complex of Minerals with Amino Acids is very stable and has high bioavailability.
To meet the requirement of dietary needs of minerals , common practice is to use Inorganic Minerals in the animal feed. However, the stability of the premix, Dioxin level and environmental rules have put restrictions on such uses. Concentration and source of trace elements are important consideration for formulating a diet.
It is observed that trace elements in Sulphate form have better bioavailability than Oxides.
Bioavilability is not a static parameter and it not only depends on the chemical and structural difference of Inorganic Bond of the trace mineral but also on the breed, age, performance , health status of the animal and on antagonistic effects within the ration (e.g. mycotoxin, crude fiber, Phytic Acid and Negative interaction between different trace and macro elements.)
The interaction of physiological, inner and outer factors are a severe handicap within the absorption process of inorganic trace minerals. High amount of Inorganic elements in the feed which are not bonded or CLAWED to a carrier (ligand) leave the body without absorption as excreta.
PRICHEMIN derived from Soya Protein (NON GMO) is the only chelate which meets all requirements of EU and AAFCO in terms of Molecular Weight of less than 800 Daltons and Dioxin Content level of less than 1 NANOGRAM per Kg (Sum of 17 congeners of Dioxin is less than 1 NANOGRAM per Kg).
