What feed do you use to keep your horses happy and healthy?

Just pasture when its available with a good mineral block.

In the winter I feed local grass hay along with a feed mixed by a local mill - forage pellets, oats & corn at 11% protein (how much depends on the horse - very little for the haflingers, more for the younger horses) and usually a general vitamin. I used Dumor that came in a big bag this past winter. The local mill stuff is 100 lbs for $16 and the vitamins are $25 per bag. I like to keep things simple and it seems to work.

Our horses have to since we switched them from Strategy to our new grain that is a custom mix. Made up of oats, molasses, lil bit of corn, and pellets.

I'll never recommend Strategy to anyone after seeing the difference.

Dang! You guys have some expensive hay! Ours is on average $4.50 a bale.
Which is a very good quality grass/alfalfa mix.
