What other animals do you have? You can feed it back to the chickens and pigs.
I believe that you can sprout grains in it to feed to a variety of animals.
Use it to make ricotta cheese.
Someone once told me you can use it as a "pre-rinse" to your hair once a month and then shampoo. Said it strengthens and supplies nutrients to the hair. I've never tried this one, so I can't back it with personal experience...but hey if you wanna try it.
