It is common practice for bison to be 'finished' on grain.

This means that the animals are fed grains (corn, wheat, oats, and/or barley.) 100 days prior to going for slaughter. This is done to fatten the animal up, increase marbling in the steaks and make for a heavier animal. For most farmers a heavier animal means a weightier pay cheque.

To be 'grass finished' means that the bison you eat have eaten fresh grass or hay bales. We believe this makes for a higher quality meat.
