1
Mix in corn oil, anywhere from an 1/8 of a cup to a pint, with the horse's food daily. Experiment with your personal mare by starting with a low amount, such as an 1/8 of a cup, and working your way up until you see the desired weight gain.

2
Take the horse to the vet to have her teeth checked and blood tests done. This will help eliminate a health reason for her inability to put on weight.
-
3
Switch to a feed designed for older horses, such as one that incorporates complete feeds or beet pulp into it.
-
4
Add a horse-specific supplement, such as Weight Builder, to the mare's feed.
-
5
Switch to a better quality hay that is higher in protein.
