PREVENTION is by far the best method. Laying a good foundation for the development of bone density through nutrition and proper stress on the bones should begin at birth. Once a horse reaches a higher level of performance training he should be moved up as slowly as possible using a program that includes an extended trot, gallops, and speed works. Studies have shown that the slow speed jog will not produce the right kind of bone density due to the fact that the principle strain direction in the jog is different than it is for the faster working gait. The extended trot produces a strain direction in the bone that is more in line with the high speed gaits. The gallops should be no more than a mile in length and should add a speed work once a week at the end of the gallop starting with a furlong and moving up to four furlongs. My recommendation for a week of training is 2 days on the jogging wheel, 3 days of a mile gallop with 1 speed work at the end of a gallop and two days off.
