(Show) vaccination Coinfections Bad colostrum intake The best security Better coinfections management To reduce vaccination cost Optimal colotrum intake «Optimizing the vaccination strategy»

Editor's Notes
Je ne comprends pas bien le haut de la diapo avec l’axe evolution (axe temps? Pourquoi « Jamais ») Taux de mortalité: les barres d’histogramme représente-t-elles le taux de mortalité? Dans ce cas, il faudrait qu’elles soient proportionnelles
Il faudrait marquer le moment d’apparition de la MAP et des vaccins PCV2
Il faudrait marquer le moment d’apparition de la MAP et des vaccins PCV2
Je ne comprends pas la recommandation pour els mater coll: vaccination truies et ajout du porcelet si pb de repro?
