I had a hot Thoroughbred that was a hard keeper. I'm not sure if this is available in your area, but I recommend Buckeye feeds. I gave Bagheera 1lb of Grow and Win and 1lb of Ultimate Finish every day. It put just over 100lbs on him in just a few months. Plus, their feeds are mostly sugar free, easy to digest, and have a fantastic nutritional content. That, and lots of good quality hay and free choice forage.
Strength is not defined by physical ability. It is determined by your actions and the compassion of your soul.
