Introduction
As part of SAPT, a satellite chaired by Daniel Sauvant (AFZ, French Association for Animal Production) and Philippe LECOMTE (CIRAD) was held on November 18 focusing on Tropical resources for food animals: new concepts food value, databases, tables and software. This satellite brought together people from 14 different geographic locations, involved in the promotion of tropical feed resources for animal feed in the tropics. Following the presentation of various concepts synthesized in the enclosed pdf, the participants exchanged their views on i) concepts of feed value or multicriteria evaluation of resources ii) evaluation of the available information sources and the methods allowing a better promotion of these resources iii) presentation of the existing databases and studies in progress and iv) their intention to share their data through collaborative projects to be launched in the near future. The following papers present the discussions that were held during this satellite.
