Several factors affect the chemical composition and, as a result, the nutritional value of feedstuffs: variations in plant genetics, environmental conditions during production, harvest and storage conditions, and more. Accordingly, the variable quality of raw materials is inevitable.

However, the use of imprecise data on feedstuffs is detrimental to animal production from a nutritional, economic and environmental perspective. In order to meet the nutritional requirements of livestock, ensure competitiveness despite the rising prices of agricultural raw materials and guarantee sustainable, environmentally friendly growth, it is necessary to have precise knowledge of feedstuff composition.

Precise Nutritional Evaluation (PNE) is a service offered by Adisseo and based on Near Infra Red spectroscopy (NIR) technology. NIR is a very convenient tool to assess the characteristics of feed ingredients. Adisseo has developed original proprietary calibrations based on in vivo data. Our technology is adapted to all main dietary ingredients (main grains and their by-products, oilseeds and their meal, and animal by-products). PNE is able to predict multiple characteristics affecting nutritional quality, such as crude protein, total and digestible amino acids, metabolisable energy for poultry, and total and phytic phosphorus.

The service is available 24/7 thanks to a web platform. More than an NIR web platform, PNE is the ideal decision-making tool for nutritionists, formulators, purchasers and quality control managers. It enables them to monitor the quality of raw materials over time, compare raw materials coming from different geographical origins, and evaluate and approve the suppliers.


1. PNE allows real-time predictions of your raw materials 

With PNE, easily access your raw material nutritional values. Upload your spectra and access your complete results in few seconds. PNE is the perfect tool to make timely decisions.


2. Accurate PNE Strengh: in vivo methods for precise values

PNE NIR predictions rely on Adisseo expertise in in vivo experimental measurements. This guarantees a high level of accuracy of digestible amino acids and metabolizable energy NIR predictions.


3. PNE Provides actionable data

Thanks to its smart and interactive charts, PNE becomes a decision-making tool and allows:

  • Accurate quality control and traceability

Aggregate and trend analyses – Follow your raw materials quality over the time, detect abnormal samples and make the right decisions.

  • Accurate raw material sourcing

Compare your raw materials origins and discriminate your suppliers thanks to PNE comparisons charts.

  • Benchmark your results

Benchmark your own PNE results against millions of PNE results. Compare your raw material values to the ones of other countries, and to the worldwide average.
