Th\u00e9matique<\/h4>\n

Dans un contexte de d\u00e9veloppement durable des exploitations laiti\u00e8res, l\u2019objectif principal du doctorat est de contribuer \u00e0 la pr\u00e9diction et l\u2019optimisation simultan\u00e9e des performances \u00e9conomiques et agro-environnementales des \u00e9levages laitiers en Wallonie.<\/p>\n

Deux types de mod\u00e8les sont actuellement utilis\u00e9s s\u00e9par\u00e9ment pour \u00e9tudier et pr\u00e9dire les performances \u00e9conomiques et agro-environnementales au sein des exploitations laiti\u00e8res. Les donn\u00e9es comptables et mod\u00e8les bio-\u00e9conomiques sont utilis\u00e9s pour l\u2019\u00e9valuation des performances \u00e9conomiques. Les analyses du cycle de vie (ACV) concernent l\u2019impact environnemental.<\/p>\n

L\u2019objectif final est d\u2019int\u00e9grer ces deux types de mod\u00e8les au sein d\u2019un mod\u00e8le combin\u00e9. Cela permettra d\u2019\u00e9valuer simultan\u00e9ment les performances \u00e9conomiques et agro-environnementales, \u00e0 l\u2019\u00e9chelle de l\u2019animal et de la ferme, et de guider les d\u00e9cisions qui, sous certaines conditions, maximisent le profit tout en minimisant les impacts environnementaux. Ce mod\u00e8le inclura diff\u00e9rentes innovations telles que l\u2019int\u00e9gration et l\u2019optimisation de plusieurs contraintes simultan\u00e9ment (optimisation multiobjectif), la prise en compte de la composante animale individuelle et l\u2019utilisation de pr\u00e9dictions issues du spectre infra-rouge du lait.<\/p>\n

Les r\u00e9sultats obtenus seront int\u00e9gr\u00e9s dans un programme informatique prototype qui pourra, entre autres, \u00eatre utilis\u00e9 dans le cadre du d\u00e9veloppement de futurs programmes d\u2019am\u00e9lioration g\u00e9n\u00e9tique incluant des crit\u00e8res de s\u00e9lection environnementaux.<\/p>\n
