Cornhusker Economics (September 26, 2012)
With drought conditions reducing forage production throughout Nebraska, many livestock producers are looking for feed alternatives. The University of Nebraska has two Excel spreadsheets that are useful tools for analyzing feed options, the Cornstalk Grazing Cow-Q-Lator and the Feed Cost Cow-Q-Lator.
The Cornstalk Grazing Cow-Q-Lator estimates the number of acres of cornstalks that are needed, as well as doing a cost analysis. Given a specific number and weight of animals and the length of time a cattle producer might wish to graze them, the number of acres of cornstalks needed is calculated based on the corn yield. Research has shown a direct relationship between corn yield and available forage from corn residue.
