Inspection of feedingstuffs

Basic investigation for the determination of the energetic feed value

Optimal nutrition of farm animals and pets requires knowledge of the need for nutrients, valuable ingredients and energy. We offer nutrient testing for all types of feed. The energetic feed value of the feed can be determined from the analysed nutrients in accordance with the applicable feed law.

The standard feed value analysis (e.g. Weender Analysis) is based on the determination of the following components:

  • Dry matter
  • crude ash, crude protein, crude fibre, crude fat
  • energy content
  • Sugar and starch

Minerals are vital substances that the organism cannot produce itself. An analysis can provide information about the supply status.

They include quantitative elements: calcium (Ca), potassium (K), magnesium (Mg), phosphorus (P), sodium (Na), chlorine (Cl) and sulphur (S).

and trace elements: cobalt (Co), iron (Fe), copper (Cu), manganese (Mn), molybdenum (Mo), selenium (Se) and silicon (Si).

Amino acids in animal nutrition

The regeneration of animal protein has a dominant function in farm animals. Depending on the animal species, physiological stage and level of performance, the demand for individual amino acids varies. Between varieties, harvest years or batches of plant raw materials, strongly changing crude protein and amino acid contents can occur. 

For an economic and demand-oriented calculation of the amino acid contents in the mixture the knowledge of the actual amino acid contents in the raw materials is necessary. This knowledge also gives you confidence when deciding on the use of synthetic amino acids. An undersupply of amino acids or an incorrect amino acid-energy ratio can lead to latent and acute reductions in performance and high feed costs. An oversupply of crude protein or individual amino acids is uneconomical and increases the nitrogen content in the liquid manure.

Our offer 

  • Analysis of the complete amino acid spectrum with special attention to the first limiting amino acids lysine, methionine, cysteine, threonine and tryptophan.
  • Individual solutions for sampling and sample transport
  • Monitoring the sampling frequency


Vitamins are organic (vital) compounds essential for most animals, which the organism needs for vital functions. Vitamins must be ingested with food.

Vitamins are divided into fat-soluble vitamins (e.g. A, E, D and K) and fat-insoluble vitamins (B vitamins, vitamin C, niacin, folic acid, pantothenic acid and biotin), which are not uniform chemical structures.

In addition, there are individual substances that have a vitamin character. Here taurine is to be called for the nutrition of the cats.

We are happy to advise you on the analysis of the vitamin content in your feed!

Contaminants are chemical substances that are not intentionally added to animal feed. Such substances may be present in feedingstuffs at various stages of production, processing or transport or may be the result of environmental pollution. Contaminants can pose a risk to human and animal health.

Environmental pollutants


Residues from production

In addition, feedingstuffs may also be contaminated by micro-organisms which affect the quality of the feedingstuff (e.g. spoilage) and subsequently have a negative effect on animal health. Microbiological testing therefore focuses on the following areas:

  • Total bacterial count, yeasts and moulds
  • Pathogenic germs (e.g. salmonella, clostridia)
  • enterobacteria

The sampling of the drinking water is carried out by our employees, who are listed as samplers for drinking water as part of the "Animal Welfare Initiative". The analysis of the water includes a microbiological and a chemical-physical test. The subsequent evaluation of the results is based on the assessment values of the "Initiative Tierwohl" and the orientation framework for the legal assessment of the "Hygienic quality of drinking water" of the Federal Ministry of Food and Agriculture.
