Types de trajectoire du statut sanitaire au cours de la carrière des vaches laitières
Résumé
This paper presents a first approach of the health over the whole life-cycle of dairy cows, a scale which is intended to define a trajectory. Trajectories are defined as the chain of health profiles on the lactation scale, which are characterized by major disorders: foul of the foot; lameness; arthritis; calving disorders; mastitis; digestive and metabolic disorders; and no disorders. A few examples of trajectories are discussed for life-cycles lasting 4 lactations
