dc.description.abstractThe subclinical mastitis represents the dominant pathology of the breeding dairy cows in the majority of world countries. The controls of such problems pass by the knowledge of the risk factors responsible of the apparition and the persistence of this pathology in the farm, like this the knowledge of the dominant epidemiological models. In our study, we have tested, to determine, by means of the questionnaire destined to the breeders of dairy cows, the control of the risk factors of intramammary infections per the breeders, like this appreciate the prevalence of subclinical mastitis in this breeding by means of the California Mastitis Test (CMT). Our results showed that the quasi totality of farmers did not respect nor the rule, nor the hygiene of milking. The results of the CMT showed that 75% of prevalence of subclinical mastitis in dairy herds, and 40% of subclinical mastitis of dairy cows. Concerning the affected quarters, the CMT results showed that 80% of quarters are healthy, 18% are infected and 2% are not functional.fr_FR
