La conduite de la reproduction du troupeau de vaches allaitantes : modélisation des prises de décision

Abstract : The aim of this work was to analyse decision-making of cattle stockbreeders according to herd management: rules, occurrences of interventions, relations with the project of production. The management of the herd was described and formalized using data collected during 2 successive surveys on 12 farms, specialized in beef production. Three categories of indicators mobilized by the stockbreeders can be discriminated: indicators dealing with the instantaneous state of the animals, indicators dealing with the individual history of the animals (lifetime performance) and exogenous indicators, independent of the animals (state of the nutritional resource, economic context). According to the project of production, these indicators are mobilized differently by the stockbreeders and 4 prototypes of herd management were then defined. This kind of analysis will be used in a modelling build-up process to simulate herd functioning.
