Alpavet - Laboratory

Forage laboratory via NIR and EDXRF minerals in association with CVAS (Cumberland Valley Analytical Services)

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. This determination depends mostly on the support of a chemical laboratory providing accurate robust calibrations of each component and type of feed.

Given the volume and breadth of chemistry evaluations that CVAS provides as the largest chemical laboratory of forages in the USA, their calibrations are the most robust of the market.

In addition, from September 2019, we offer mineral analysis by Energy dispersive X-ray fluorescence (EDXRF), a fast and accurate method to detect minerals on any type of feed.

Type of analysis that we carry out:

NIR NUTRITION ANALYSIS AND MIXED MINERAL DETERMINATIONS

NIR 1 Analysis of forages

NIR Analysis 1 includes determination of dry matter, moisture, crude protein, protein bound to ADF, protein bound to NDF, soluble protein, ADF, NDF, lignin, starch, ethanol-soluble carbohydrates, water-soluble carbohydrates, fat, ash, calcium (Ca), phosphorus (P), magnesium (Mg), potassium (K) and pH in ensiled forage. Calculated values are provided for RFV (forage only), available protein, adjusted protein, degradable protein, NEl, NEm, NEg (NRC summative energy equations), CNS and CNF.

NIR (Plus Option)

This option provides additional value and is added on top of NIR 1. Graphical reports and our extended-range reports are produced using the Plus option. Added nutrients include: NDF digestibility at 12, 30, 120, and 240 hours, plus uNDF values, Fermentation parameters and soluble fiber in ensiled forages, Fatty acid values and amino-acid nitrogen as a percentage of total nitrogen, Starch digestibility at 7 hours, RFQ in forages

Wet-Chemistry Determinations

Grain processing score (CSPS) for corn silage. A tool to assess kernel processing by forage choppers, defining starch particle size and its expected impact on both ruminal and total-tract digestibility. Must be added to an NIR 1 analysis.

peNDF Evaluation (Forages or TMR)

Determination of physically effective NDF according to the Mertens model. Must be added to an NIR 1 analysis.

Particle-Size Evaluation (By Penn State or Z-Box)
