Trace Minerals

Trace minerals are essential minerals required by horses in very small amounts to support a wide range of physiological functions. Key trace minerals include copper, zinc, selenium, iron, manganese, iodine, cobalt, and chromium. Despite their low concentration in the diet, these minerals are critical for enzyme function, hormone production, antioxidant defense, immune function, and structural development.

In equine nutrition, trace minerals are typically added to feeds through mineral premixes containing inorganic (e.g., sulfates, oxides) or organic (e.g., chelates, proteinates) forms. The bioavailability of each form varies, with organic complexes often showing improved absorption under certain conditions. Trace mineral requirements differ based on age, workload, reproductive status, and health.
