1/11/13: Adisseo launches an interactive version of its Rhodimet® Nutrition Guide

Adisseo has introduced an electronic version of its Rhodimet® Nutrition Guide which is now available for nutritionists worldwide.
Back in July, Adisseo published its new Rhodimet® Nutrition Guide (RNG), a collection of amino acid recommendations for poultry, swine and aquaculture. Following a flip-chart version developed in August, the interactive guide is now available for personal computers and tablets. The e-RNG 2.0 supplies amino acid requirements of an extensive range of animal species and strains, and provides total, digestible composition and digestibility coefficients of amino acids in raw materials. In addition, the amino acid composition of more than 30 different raw materials is added in a separate section. This data is extracted from the Precise Nutrition Evaluation (PNE), the NIR Service from Adisseo. 

PNE allows the prediction of digestible amino acids, metabolizable energy and phytic phosphorus of raw materials, on the basis of a unique in-vivo database built on more than 200 digestibility trials carried out in Adisseo Center of Expertise and Research Nutrition (CERN) France.  Based on an innovative modelling approach developed initially by Pierre-André Geraert, the Innovation Marketing Director at Adisseo, the amino acid requirements are expressed in gram/animal/day according to weight gain (or egg mass).  

The initial version was based on the data available in 2002. Many people were interested to check if the modelling approach was still valid on more recent data. As a consequence, the present version is using all the new published works till 2012, confirming the methodology for a larger number of essential amino acids. This approach gives a simple way to adjust amino acid recommendations to field results more precisely than a constant amino acid to lysine ratio. They are adaptable to standard or specific conditions and various feeding programmes.

“A recent trial conducted in Thailand shows that formulas based on these recommendations resulted in a better adjustment of digestible amino acid requirements to sustain growth with a better economical return compared with usual recommendations”, says Dr Magalie Nonis, an animal scientist at Adisseo. “This tool is available in nine languages: English, French, Spanish, Portuguese, German, Polish, Turkish, Arabic and Chinese,” added Pierre Dalibard, the company's global technical manager.

The e-RNG 2.0 is accessible via the Adisseo Brands website (, the Apple App Store or Google Play for tablets. In order to access the e-RNG 2.0, users must download the application and inset an access code to establish the first connection.
