Analysis Laboratory

Page reviewed:  22/05/2025

We offer advanced analyses covering the entire production chain – from raw ingredients and feed to animal response and final product quality.

With a focus on feed and milk analysis, as well as biological samples such as blood and faeces, we support research, development, and education both within SLU and through external collaborations.

What We Analyse

We specialise in analysing samples across the full production cycle – from raw materials to finished products.

Common sample types:

  • Feed and raw materials: forage, cereals, concentrate feed, plant material, press juice, mussels, etc.
  • Animal products: milk, meat, eggs, fish
  • Biological samples: blood, tissue, urine, faeces

Common analytical parameters:

  • Dry matter
  • Ash
  • Crude protein (Kjeldahl method)
  • Soluble and fibre-bound nitrogen
  • Ammonium nitrogen
  • Free amino acids
  • Nitrate/nitrite
  • Extractable (EG) fat
  • Fatty acids
  • Volatile fatty acids (VFA)
  • Sugars and starch
  • NDF, ADF, lignin
  • Plant fibre
  • Water-soluble organic matter (VOS)
  • Buffering capacity (for silage)

Methods we use:

  • Kjeldahl
  • Soxtec
  • HPLC/UHPLC
  • Gas chromatography (GC)
  • ELISA
  • In sacco (rumen degradability)
  • Gas in vitro (degradation kinetics in rumen and hundgut)

Our Equipment

We use modern, specialised laboratory equipment to ensure high precision and reliable results. Below is an overview of our technical capacity:

Sample preparation and general analysis:

  • Freeze dryers, drying ovens, muffle furnaces
  • Mills for grinding feed and plant material
  • Bomb calorimeter
  • Spectrophotometers
  • Microplate readers

Quantitative and chemical analysis:

  • Kjeltec (crude protein)
  • Soxtec (fat)
  • FTIR (milk analysis)
  • AutoAnalyzer and FIA
  • Chromatography:
  • HPLC
  • UHPLC
  • GC

Molecular biology and physiology:

  • PCR and gel electrophoresis equipment
  • Ussing chamber
  • Cell culture facilities

We conduct analyses for:

  • Researchers and PhD students within our department
  • Other SLU units working with animal and feed production
  • External clients in agriculture, industry, and research
