Livestock feed analysis

Proximate Analysis is a partitioning of compounds in a feed into six categories based on the chemical properties of the compounds. The six categories are:
  1. moisture
  2. ash
  3. crude protein (or Kjeldahl protein)
  4. crude lipid
  5. crude fiber
  6. nitrogen-free extracts (digestible carbohydrates)
A method for the quantitative analysis of the different macronutrients in feed is the proximate analysis, based on the proximate analysis that was developed in 1860 by Henneberg and Stohmann in Germany.








  1. Determination of moisture/dry matter (D.M) in a feed sample 
  2. Determination of crude protein in a sample
  3. Determination of ether extracts (EE) or crude fat
  4. Determination of crude fiber in a feed sample
  5. Determination of crude ash in a feed sample
  6. Determination of nitrogen free extract (NFE) in a feed sample
