So, my friend got a 26yr old TB mare last year and she was really really skinny! We got her on grain and extra hay, we used beat pulp for a while but she didn't really like it so we took her off of it. She has been wormed and I think her teeth are all right. She has gained a little bit of weight, but she still needs a lot of weight. Is there anything you can suggest for her? Right now she is on Rice Bran Oil and i think a grain for older horses.
