Provide a well-balanced diet appropriate for your horse’s age and workload to help keep his feet healthy. When his diet is on point, so too will be his hoof growth…usually. Some horses, despite a fine-tuned diet, require nutritional help with hoof growth. In such cases, biotin supplementation can be beneficial. Hooves respond to other nutrients as well, so a well-formulated hoof supplement should contain zinc, iodine, and methionine, in addition to biotin (ker.equinews.com).
