During this fall season I have seen several articles and columns come across my desk that discuss the value of testing forage before entering the winter feeding season. I can easily recommend you collect forage tests, but what should you do once you have the tests in hand? Consider the following resources as a starting point. These resources can help you understand if the forage you have available is adequate to meet energy needs. Are the values on your forage test high or low? Nutrients values for beef cattle are summarized by the National Research Council in a report titled “Nutrient Requirements of Beef Cattle”, which is currently in its eighth edition. An online search will show several examples of these tables and one concise source is available here: http://www.aces.edu/pubs/docs/A/ANR-0060/ANR-0060.pdf
