Manganese (Mn)
AT A GLANCE:
Manganese and its roles:
- Involved in bone formation
- Stabilization of liver metabolism regarding fatty acids
- Tissue respiration

Manganese is abundantly present in nature, and essential for both plants and animals. Manganese is poorly bioavailable. Its role is linked to its red/ox capacity.
The estimated needs for manganese are 6 mg per day and per kg of metabolic weight.
The metabolic weight corresponds to the horse's weight to the power of 0.75: for example a horse of 450 kg : 450 0.75 = 98 kg of metabolic weight; such a horse will need 588 mg of this trace element per day from dietary sources.
