Before you ramp up the level of distillers grains in a ration, consider the ramifications on your nutrient-management plan, says Roger Epley, independent nutritionist in Neenah, Wis. For example, a 3,000-cow dairy that feeds 30 pounds of wet distillers per cow per day (as-fed) generates more nutrients than the same size dairy not feeding distillers. That equates to the following difference in nutrient levels per year:

  • One truckload of sulfur.
  • One truckload of phosphorus.
  • Two truckloads of nitrogen.

This can be a concern if you don’t have adequate land base for this volume of nutrients, Epley says. It could mean the difference between feeding it or not feeding it at all.
