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

Dry Matter, Moisture, Crude Protein, ADF protein, NDF protein, Soluble Protein, ADF, NDF, Lignin, Starch, Sugar, Fat, total fatty acids, unsaturated fatty acids, Ash, Calcium (Ca), Phosphorus (P), Magnesium (Mg), and Potassium (K) and pH by the traditional method of ensiled forage. Calculated values are provided for Available Protein, Adjusted Protein, Degradable Protein, NEl, NEm, NEg (OARDC Summative Energy Equation), and NFC.

NIR 1 Forages Analysis Plus Option (+)

NIR Plus Option provides a 30 hrs. 120 hrs. and 240 hrs. NDF Digestibility, a uNDF at 30 hrs. 120 hrs. and 240 hrs. and a NIR evaluation of fermentation acids (for ensiled forages). It provides values of Lignin, fatty acids, and soluble fiber. For corn silage, the NIR Plus Option provides additional value of starch digestibility at 7 hrs. and reports low, medium and high contamination by ashes.

OTHER NUTRITION ANALYSIS

Analysis of Corn Silage Processing Score (CSPS)

This tool defines adequacy of corn silage processing by forage harvesters. In addition, the CSPS tool defines starch particles size and can be used to evaluate the inference of starch in corn silage on ruminal digestibility and total digestive tract.

Evaluation of particles size using Penn State or Z-Box

Determination of the distribution of particles and effective fiber of different forages and unifeed samples.

Oven-drying of Dry Matter

Determination of % of DM dried in oven.

FTIR MILK ANALYSIS

FTIR Milk

Determination of the following parameters via FTIR, with calibrations done by a certified chemistry laboratory: Fat, Protein, Casein, Lactose, Fatty acids (De Novo, Mixed, Preformed), Total solids, Non-fat solids, Urea, Conductivity, pH and Cryoscopic constant.

FTIR Milk Laboratory

Determination of the following parameters via FTIR, with calibrations done by a certified chemistry laboratory: Fat, Protein, Casein, Lactose, Total solids, Non-fat solids, Urea, Conductivity, pH and Cryoscopic constant.

Analysis of fatty acids in milk is available under Barbano Lab calibrations from Cornell University. This allows the differentiation of fatty acids de novo, mixed, and preformed and its practical application to evaluate ruminal function and NEFA control in post-partum.
