Since Max will be coming to a place closer to me, I wanted to start out getting some food that's closer to his new digs. I've found a food that is very reasonable and "supposedly" better than what I was feeding him. I used to feed him 10% sweet feed. 1/2 lb in the morning, half pound at night. There is 12% sweet feed available for a cheaper price and close by. BUT, there is an issue. On the packaging, it says "Supplement for horses". The other 10% sweet feed didn't say supplement. I understand if it just means that he needs forage as well, that's an understood thing for me, but what could it possibly mean by "supplement"??
