BTV sero-positive from seven provinces in north western Algeria, seven provinces were selected. A total 272 animals included three phases of blood collection in season of autumn were randomly collected for detection of BTV group specific antibodies through competitive ELISA (c-ELISA) for assessment of situation epidemiological by prevalence and presence of Culicoides trapping in sites was revealed seropositive. The significant (p<0,05) highest prevalence of BTV was recorded in province Oran followed by Mostaganem, Relizane, Mascara, Tiaret, Chlef, whereas, the lowest sero-prevalence for BTV was recorded in cattle in province
