Options for Feeding the Cow Herd When Hay Supplies are Short-2013 version (pdf) is a fact sheet that has been updated with current pricing scenarios and addresses the following options: limit feeding hay, limit feeding corn silage, and substituting corn for a portion of the hay in the ration.
Substituting Corn for Hay Economic Comparison Spreadsheet (excel) This spreadsheet builds helps cow-calf producers evaluate the economics of substituting corn for some of the hay in the ration. It includes a calculator for determining breakeven hay prices for when corn substitution should be considered, and provides an example producers can enter their own numbers to get some estimates on how much money might be saved with substitution. Producers will still need to have balanced rations formulated and do further comparisons, but the spreadsheet can provide a good starting point to evaluate substitution as a potential option.
