Here is a very interesting program on understand hay, hay tests, and amount of corn to supplement if required. I came across this the other day. It is from Ohio State University in two parts.
This is the best thing I have seen about hay and is done on a layman (not phd) basis.
I have been concerned about my own cow/heifer group, due to start calving in mid March. Are they getting enough nutrition from the hay only they are eating, especially with the sub zero weather and snow in Wisconsin this winter. More coming in the next few days I hear.
What is also interesting about this OSU program is after evaluating hay, there is an example of how to make up a TDN deficiency with just 2.5 lb of corn per day. And contrary to our focus on protein, this program shows that for beef cows, the energy component of hay as measured by the TDN is often limiting.
Here is the program. The whole thing takes 2 hours to watch but it may be a very well spent 2 hours when you have time. There is also a very clear BCS chart with pictures that is the final judge of how our cattle are doing.
What is said at the end, even with $6.42 local corn purchased, corn makes sense. And for cow/calf at least, high corn prices do not need to affect us very much.
As far as finishing cattle on corn, I think we will see more of a shift to DDG's coming out of ethanol plants rather than shell corn making up more of a finishing ration. And as ethanol ramps up there should be more DDG's etc available. jmho.
Here is the Ohio State University hay program part one, part two and the BCS chart:

I hope some of you find this useful. Jim
