iO Biotin

Biotin is a vitamin that is an essential nutrient for all animals.  Some of its many functions include fatty acid synthesis, protein and energy metabolism and cell proliferation.  For horses and other stock biotin is the best known and commonly most used supplement to improve hoof quality.

Natural Sources

There are two sources of natural biotin.  Biotin is contained in most feeds and forages, particularly lush green feeds.  In addition to this, biotin is produced in the gut of an animal through microbial synthesis.

Influences of Biotin on Hoof Strength

The hoof contains a structural protein called keratin, which forms an internal support lattice, similar to steel girders in a building.  The cells that form the hoof horn are bonded together by a cementing substance, similar to that of mortar.  Biotin is specifically required for the production of keratin and the cementing substance of the hoof wall.  If the nutrient supply during the forming process is poor, the horn quality will be compromised.
