As an affiliate lab of Cumberland Valley Analytical Service the SCDHIA forage lab has aligned itself with the largest chemistry based forage lab in the U.S... As such, they have the resources to generate some of the most extensive NIR calibrations in the industry. NIR is the method by which all samples processed onsite at the SCDHIA forage lab are analyzed.

Why NIR?

Near Infrared Reflectance spectroscopy (NIR) allows for rapid determination of multiple nutrients and characteristics of a feed or forage. It is a fast, cost effective process available for evaluation of most forage types. Applying the NIR calibrations developed by CVAS gives us the expertise needed to be a leader in the provision of NIR services.

For a listing of forage applicability and predicted nutrients, you can use the following link to the CVAS website:

Below is a list of NIR packages offered by the SCDHIA Forage Lab. For NIR packages requiring wet chemistry, SCDHIA will handle the NIR analysis and the ground sample will be shipped overnight to CVAS for analysis.

Package Description Price
NIR1 Package The NIR 1 Analysis includes tests for Dry Matter, Moisture, Crude Protein, ADF Protein, NDF Protein, Soluble Protein, ADF, NDF, NDFom, Lignin, Starch, Sugar, Fat, Ash, Calcium (Ca), Phosphorus (P), Magnesium (Mg), and Potassium (K) with pH by traditional method on an ensiled forage. Calculated values are provided for Available Protein, Adjusted Protein, Degradable Protein, NEL, NEM, NEG (OARDC Summative Energy Equation), and NFC. $17.75
