I don't feed senior, I never said that I do. I don't feed senior because its cheeper for me not to.
You don't have to overload them with senior and over feed... do your homework
Sorry but if I want my horse to get the adequate amount of "everything in senior" I would need to over feed my horse.
All senior feeds arent complete, just the good brands. There are probably feed mills all over the place slapping a senior label on the feeds that are just higher in calories.
I didnt say anything about hay... but Complete feed, at least where I buy feed from, means it is completely balanced meaning you don't need to add hay to it if you follow the feeding guide.
