Th\u00e9matique<\/h4>\n

Le doctorat men\u00e9 a pour but de maximiser les r\u00e9sultats \u00e9conomiques des \u00e9levages laitiers en Wallonie en optimisant la gestion du troupeau. Diff\u00e9rents param\u00e8tres de gestion de troupeau sont travaill\u00e9s pour trouver la gestion qui permet la meilleure rentabilit\u00e9 en fonction du type de ferme.<\/p>\n

Le param\u00e8tre intervalle entre deux v\u00ealages est actuellement \u00e9tudi\u00e9. Le postulat du \u00ab\u00a0un veau par vache par an\u00a0\u00bb est remis en cause suite aux \u00e9volutions du syst\u00e8me laitier: augmentation des performances de production laiti\u00e8re, baisse de fertilit\u00e9, maladies au v\u00ealage,\u2026 . Quel est aujourd\u2019hui l\u2019objectif d\u2019intervalle entre deux v\u00ealages \u00e0 poursuivre pour g\u00e9n\u00e9rer le meilleur revenu?<\/p>\n

Cette th\u00e8se r\u00e9pond aux attentes actuelles, en effet le commerce laitier mondial est en plein bouleversements: la fin de l\u2019\u00e8re des quotas, la production grandissante dans chaque continent et la demande incertaine en lait rendent la situation instable et plongent l\u2019ensemble des \u00e9leveurs laitiers dans l\u2019incertitude et l\u2019anxi\u00e9t\u00e9. Face \u00e0 cette situation, les \u00e9leveurs se doivent d\u2019\u00eatre irr\u00e9prochables dans le management troupeau pour assurer la rentabilit\u00e9 de l’exploitation. Ils doivent chercher \u00e0 produire le plus avec le moins. Il s\u2019agit donc pour eux de poursuivre l\u2019optimum pour chaque param\u00e8tre technique de management.<\/p>\n

De plus, la recherche de l\u2019optimum dans l\u2019\u00e9levage laitier va de pair avec la volont\u00e9 d\u2019une meilleure efficience dans les syst\u00e8mes de production agricoles en g\u00e9n\u00e9ral, pour s\u2019inscrire dans un d\u00e9veloppement durable et r\u00e9pondre aux d\u00e9fis alimentaires et environnementaux du futur.<\/p>\n

Mais les recommandations en \u00e9levage laitier sont nombreuses et souvent contradictoires. C\u2019est pourquoi ce projet doctoral trouve tout son int\u00e9r\u00eat \u00e0 faire le tri entre toutes ces affirmations et \u00e0 proposer ses propres conclusions \u00e0 partir d\u2019une recherche \u00e0 la fois vari\u00e9e et innovante.<\/p>\n
