Schmallenberg virus (SBV), emerged in 2011, cause abortion, diarrhea and reduced milk yield in cattle and sheep. The aim of this study was to determine the duration of SBV specific maternal antibodies in calves. For this purpose, 148 sera collected from cattle and calves were tested for SBV specific antibodies with ELISA. SBV specific antibody response was monitored during 8 months in cattle and their calves. SBV seropositivity was detected in 26 out of (six of them from newborn calves) 148 samples (17.56%). Calves were tested for SBV specific antibody for 8 months after colostrum intake. Seropositivity in calves born from SBV seropositive cattle is thought to be due to colostral maternal antibodies. All SBV seropositive calves became seronegative after 8 months and SBV seropositivity of cattle was determined as 13.51% (20/148). In conclusion SBV maternal antibodies persistence for 8 months in calves is confirmed and therefore it is suggested that serological monitoring for SBV antibodies in calves should be initiated after 8 months of age. Furthermore it is necessary to investigate SBV specific protecting and interfering antibody levels for evaluation of vaccination efficiency.
