Effets des maladies sur les performances zootechniques

Longévité, croissance, reproduction, production laitière sont autant de paramètres potentiellement impactés de façon Clinique ou subcliniques lors de maladies.

La quantification de ces pertes est cruciale pour prédire le bénéfice espéré de mesures de maîtrise, de même que pour convaincre les décideurs de la pertinence de leur mise en œuvre. Ces travaux sont fréquemment conduits en partenariat avec l’équipe MODEC afin de coupler une approche observationnelle et par modalisation.

Travaux menés durant la période 2006-2010

  • La quantification des effets de l’infection par Mycobacterium avium subspecies paratuberculosis (Map) sur la production laitière et les performances de reproduction >>>
  • L’estimation de l’impact du génotype CVM sur le taux de retour des vaches >>>
  • L’évaluation de l’impact des maladies respiratoires sur les performances de croissance

Projets en cours

Les projets en cours concernent l’évaluation de l’impact zootechnique des maladies suivantes :
