I guess I'm lucky. Never having to buy feed, the only rations I ever have to figure out is bales divided by feeding days. We take hay and greenfeed (oats) off about 1000 acres, and that's what the cattle get. Hay is alfalfa brome timothy cross, but mostly alfalfa. I haven't had hay tested in years because regardless of what it tests, that's what they get. Of course, a guy naturally trys to mix the poorer hay with the better. And it has allways amazed me that I can figure on 5 bales (3 1/2 ton) per winter per cow no matter the size of cow. If I have at least that much in the hay yard, the cows winter fine. Not very scientific, but it works in my application.
