I have been using Animal Trace Minerals for almost 10 years. I have used them on riding horses, driving horses and our ponies. Not only do they produce strong hooves but also promotes growth. I had to even cut back on the amount with some, as their hooves were growing too much. Our farrier says that our horses have the best feet of all his customers. They are much healthier since I started feeding the minerals. In addition to the quality of the hooves, the minerals produce a shiny healthy coat in all of our horses. By adding them to the diet, you must start from the inside for a healthy horse.
