Popis: | Les mammites subcliniques sont des affections incideuses de la glande mammaire mais qui impactent negativement la production de la vache laitiere. Il s’avere necessaire de faire le diagnostic en vue de les controler. Objectif : Le present travail avait pour objectif de determiner la prevalence des mammites subcliniques dans les elevages traditionnels de la region de Kaolack au Senegal. Methodologie et resultats : Au total 101 vaches en lactation des elevages traditionnels de la zone periurbaine de Kaolack ont fait l’objet de l’etude. Le California Mastitis Test (CMT) et le Comptages des Cellules Somatiques (CCS) avec le Delaval cells counter (Delval, Tumba, Suede), ont ete utilises pour analyser les echantillons de lait preleves. Les prevalences ont ete de 11,9% et de 10,9% en utilisant le CMT et le CCS respectivement. Il n’y a pas eu de difference significative entre prevalences obtenues par les deux tests (p=0,824). La prevalence des mammites chez les vaches metisses (12,5%) a ete significativement plus elevee que celle des vaches de race locale Gobra (11,8%) (p=0,007). Par contre, le rang de mise bas n’a eu aucun effet sur la survenue des mammites (Odds ratio = 1,542 ; 95% IC : [0,884-2,690]). Conclusion : La prevalence des mammites obtenue dans les elevages traditionnels permet de dire qu’il faut envisager une prise en charge efficace des vaches malades et ameliorer la production laitiere. A la lumiere de nos resultats, le test de CMT qui est fiable rapide simple et efficace peut etre un bon moyen de detection rapide des mammites subcliniques dans les elevages traditionnels Mots cles : California Mastitis Test, Comptage Cellules Somatiques, Mammite subclinique, vache laitiere, Senegal Subclinical mastitis is an insidious infection of the mammary gland which negatively affects the production of the dairy cow. Thus, it is necessary to make the diagnosis in order to control it. Objective : The objective of this study was to determine the prevalence of subclinical mastitis in traditional livestock (cows) in the region of Kaolack in Senegal. Methodology and results : A total of 101 lactating cows from traditional Kaolack peri-urban farming were studied. The California Mastitis Test (CMT) and Somatic Cell Counts (CCS) using Delaval cells counter (Delval, Tumba, Sweden) were utilized to analyze the milk samples. The prevalences were 11.9% and 10.9% using CMT and CCS respectively. There was no significant difference between the prevalences obtained by the two tests (p = 0.824). The prevalence of mastitis in crossbred cows (12.5%) was significantly higher than that of local Gobra cows (11.8%) (p = 0.007). On the other hand, the calving rank had no effect on the occurrence of mastitis (Odds ratio = 1.542 ; 95% CI : [0.884-2.690]). Conclusion : The prevalence of mastitis obtained in traditional livestock suggests that effective management of sick cows should be considered in order to improve dairy production. In light of our findings, the CMT test which is reliable fast simple and effective can be a good means of rapid detection of subclinical mastitis in traditional dairy farms.
