I purchased a big 5 year TWH gelding about three months ago. He is a broad, well muscled fellow for sure, but he is also about 200 Pounds overweight in my opinion. He is turned out daily, from 8 AM to around 7 PM. However, his pasture is over grazed and there is not a lot of grass to be consumed. At night, he gets a "flake" of hay. I have not been able to ride or exercise him much due to undergoing a back surgery about three weeks after I bought him. I am hoping to peel some weight off of him over the winter. I will supplement his hay intake with feed. Any suggestions for a good diet feed that will keep him nourished but will also result in some weight loss? My hope is that by spring, his weight will be optimal and my back will be healed so that we can both be ready to resume a very regular riding and training regimen.
