Iron and its roles:
- Essential for the haem formation, responsible for oxygen transportation in red blood cells
- Important during growth
Iron is an ubiquitous element which is essential for plants and animals. Although an iron deficiency is very rare in equines, an adequate intake is required in order to obtain a good bioavailability of the other trace elements.
Its role is linked to its oxidant capacity and its property as a catalytic agent.
If we consider the horse's needs for iron, they are estimated at 6 to 10 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 580 to 970 mg of this trace element per day.
