Manganese chelate of amino acids hydrate

What it is. Nutritional additive from functional group 3b (trace element compounds), consisting of a complex of manganese and amino acids derived from soybean protein hydrolysate, in which manganese is chelated by covalent coordinate bonds. It is presented as a powder with a minimum manganese content of 8 %.

What it is for. This additive is used to meet manganese requirements, a trace element involved notably in bone metabolism and enzymatic functions. It is authorised for all animal species and incorporated into feed in the form of a premixture. It is generally used in formulation to adjust manganese supply alongside base raw materials.

Points to watch. The maximum total manganese content is 100 mg/kg of complete feed for fish and 150 mg/kg for other species (total addition together with other manganese sources). Handling the additive and premixtures requires personal protective equipment (skin, eyes, respiratory tract) due to risks linked to heavy metals, notably nickel, which may be present.
