Forage Lab

The laboratory is equipped to provide both NIRS (near-infrared reflectance spectroscopy) and conventional wet chemistry testing. Samples can be analyzed for dry matter (DM), neutral detergent fiber (NDF), acid detergent fiber (ADF), crude protein (CP) and minerals (Ca, P, Mg, K, Cu, Zn, Mn). The standard procedure for samples received by the laboratory includes DM (oven dried) and CP, NDF, ADF and TDN (Total Digestible Nutrients) estimated with NIRS. Wet chemistry is performed on samples unsuitable for NIRS analyses. Additional analyses, such as in vitro true digestibility (IVTD) and soluble nitrogen concentration, are also performed for many research projects.
