Fecal/Manure Testing for Certified Feed Management Planners

Feed management is the process of managing the quantity of nutrients fed to livestock for their intended purpose. This involves development of diets that supply the quantity of available nutrients required by livestock for maintenance, production, performance and reproduction. Supplying nutrients in excess of animal requirements results in additional nutrients being excreted.

The NRCS Conservation Practice Standard (Code 592) Feed Management was developed with the purpose of supplying the quantity of available nutrients required by livestock, while reducing the quantity of nutrients, nitrogen and phosphorus excreted in manure by minimizing the overfeeding of these nutrients. Currently, feed management is an option of a Comprehensive Nutrient Management Plan (CNMP). Producers can request feed management as part of a CNMP. Only certified feed mangement planners (CFM) can complete a plan. One requirement is that fecal/manure samples be taken to set the baseline prior to any feed changes being made and fecal/manure samples taken over the course of the plan to document ration or feed management changes.

Fecal/manure samples submitted as part of this program must be tested by a certified manure testing laboratory. Penn State's Agricultural Analytical Services Laboratory is certified by the Minnesota Department of Agriculture (MDA) for manure testing. Visit the MDA web site for a list of other certified manure testing labs.

What to Test For
