Résumé
The purpose of this research is to establish a model of Koch's postulate for reproducing coccidiosis in broilers by co-infection with eight most common Eimeria spp. involved in this economic disease, in an attempt to use this model in future evaluation of new controlling biologics. Four groups of broilers each challenged at a different age (14, 21, 28, and 35 d) with an equivalent number of sporulated oocysts of eight Eimeria spp. had a reduction in their mean weight gain of 10.2% compared to the four parallel control groups of birds that were deprived of the challenge. The mean feed to live body weight conversion ratio increased significantly from 1.5 in the four unchallengedcontrol groups to 3.1 in the four challenged groups (P
