The INRAE-CIRAD-AFZ feed tables include chemical data are derived from analyses performed in feed laboratories using standard methods and then corrected to produce consistent chemical profiles. Nutritional values for livestock, poultry and fish are derived from in vivo trials and then established by equations. Environmental impact values originate from the ECO-ALIM project.

The tables include values for net energy, metabolizable energy and digestible energy values for growing pigs and adult pigs, values of digestible (ileal standardised) amino acids and digestible phosphorus (with or without phytase). Energy digestibility is estimated using prediction equations specific for each feed material and then used to estimate net energy values.

The tables provide values of metabolizable energy (corrected for a zero nitrogen balance), digestible energy and nitrogen digestibility.

The tables include values for digestible energy, nitrogen digestibility and digestible phosphorus for salmonids (salmons and trouts).

The environmental data for feeds included in these tables have been produced through ECO-ALIM, a French project led by IFIP and funded by ADEME and the French Ministry of agriculture. IFIP, Arvalis, Terres Inovia and INRA collaborated with the feed industry (SNIA, Coop de France Animal nutrition, AFCA-CIAL and feed manufacturers) to produce environmental data suitable for inclusion in least-cost feed formulation with a goal to reduce the environmental impact of livestock feeds and of the resulting animal products (meat, milk, eggs).
