Manganese Oxide (MnO)

Feed Grade

Manganese is an important micronutrient, the deficiency of which disrupts growth and results in disorders of the bones and central nervous system. As the animal body does not produce Manganese, it needs to be supplemented externally. Thus, it forms an important constituent of all Animal and Cattle feed. Different grades of Manganese Oxide are manufactured ranging from 50% Mn to 62 % Mn. It is used in Animal Feed Industry, Fertilizer Industry, and Welding Industry etc. NPPL manufactures Manganese Oxide as per European feed specifications, with heavy metals within specified limits.
