Representative Sample

First and foremost, a representative sample is important. We ensure this by mixing the sample we have received and taking out about 100 grams of silage feed and weighing it. The sample is placed in a drying cabinet for one day and when we take it out it is weighed again. Based on the weights we calculate the dry matter and the sample is ground and NIR-scanned.

NIR Scanning and the Data Sets We Use

We use NIR-scanning on dry sample. This is the established and recommended method. About 25-30 years ago a method was introduced where samples were scanned without drying and grinding them first. It was quickly adopted and is an accepted method for grain.

In 2023 we conducted new tests on different wet calibrations and the results support our earlier conclusions.

Calibrations

Our calibrations consist of over 2000 samples that we have analyzed for OMD, ash, crude protein, NDF, INDF, soluble protein, fat and sugar. For pH, lactic acid, acetic acid, butyric acid, ammonia, nitrate, chloride and minerals we have over 1000 samples in our database. About 80% of the samples are Norwegian and the rest are mostly Swedish.

Quality Control

We store the raw samples for at least one week after analysis for possible control. If the customer wishes to check what is written on the sample bag or has any doubt, we can analyze the sample again.
