Did it for several years. My experiences:
Made money above what I would have gotten for the calves as feeders. However, my money was tied up a longer, so maybe a wash.
Learned a lot. Best cows need culling, while the middle of the road need to be what you send. Bigger isn';t always better, watch what grid you're selling on.
The risk and reward isn't worth it. May get a premium on some, and get docked on others. It's a long time to get all to grade choice or prime.
It is the most confusing thing in regard to culling cows you will ever deal with. A good steer will bring you a $175 premium, while a grade 4 will cost you $300.
Probably averaged around $75 a head profit over the years, but when calves got high, I quit. When I could get $900 for a calf, didn't see the need.
Need to have 500 head to make it worthwhile. Not enough money in it for the small producer, 100 head or so. You can mix a pen of steers and heifers, I did. Sent mine to Gregory Feedyard in Iowa.
Good bunch. gs
