Hello, I'm brand new here and this is my first post. I've recently been given a 19 year old 1/2 Arab- 1/2 Tennessee Walking horse gelding by my grandmother who could no longer care for him. He'd gotten very fat before I got him and must have foundered even though he's never been lame. His coffin bone has rotated so much I'm afraid it's about to break through. His weight is good now. I'm feeding him mature grass hay and would like to add a pound or two of beet pulp, 1/2 cup of corn oil, and a vitamin of some sort (looking for suggestions) to his diet. I lost my job right after i got the horse:? so my budget is tight, tight...but I still want to do everything I can to take excellent care of him so his life is long and happy. There's a lot of sentimental value here since my grandmother gave him to me and his sire was my lesson horse when I was a kid. I love this sweet ole guy.
