I've just started giving my gelding a supplement in grain like form and sand clear(Only feeding it for 6 more days). He likes the supplement but hates the sand clear. I have been chopping up an apple and mixing it in well but he's still not a fan. I am wondering if there is anything I can put in this to make it more appetizing. He is on a 0 sugar diet(No grain), hates mulases and sirup. I am about 40 miles from my closest feed store so keep than in mind. Thanks!!
