BSG has and will continue (when we can) to test our sires in the Trial-County Steer Carcass program, once recognized by the American Shorthorn Association.
You know a lot of people assume they have cattle feeding figured out because you just need to select for growth and muscle.

Here is a nice discussion from Mark Gardiner of Kansas on using the sire summary (EPD database).
