Feeding clover to horses

Clover can be a good feed source for most horses because it provides useful energy and adequate protein and fiber. You can use clover in hay or pastures.

Clovers can sometimes mold, which causes slobbers, photosensitivity (reactive to light) and bleeding. These conditions can occur after horses eat affected clover either fresh or as hay.

Even with the chance of these problems, clover is still a useful forage for horses.
