I am no cattle pro, but I will try to tell you what I know. There arent a ton of guys fattening cattle around here anymore. The guys that do are mainly fattening black angus. Buy in at like 800-900 and go from there. Mainly feeding silage with high moisture corn. The only close sales stables are New Holland and Vintage. The local farm paper has sales reports every week. I dont really understand all the reports, but I could look through it and tell you some of the information if that would help you. They post sales volume, price, and the grade?
Also, there is an order buyer that is at the sales stable all the time. His name is Ron Ranck. If you call the stable and ask for his number they will give it to you. He could tell you what you need to know. He knows his stuff... If you want the sale report from the paper let me know.
