Often when we dont feed to the correct exercise level of our horses their behaviour changes, they can have too much unwanted energy or you may find them runninng out of steam in a ride or competition!
Besides unwanted bahaiour horses can either gain weight or lose too much weight if we are not feeding to match their output!
