Özet

In this study, the possible effects of BHV-1, BHV-4 and BVDV involving abortions in the selected dairy cattle herds in Kars province of Turkey were serologically investigated. Serum samples obtained from 140 aborted cattle where frequent abortion cases frequently occurred during first and second trimesters of gestation last a few years were analyzed for the presence of specific antibodies for BHV-1 and BHV-4 using ELISA and BVDV using neutralization test, respectively. The results showed that 61.4% (86/140) and 29.3% (41/140) of samples were positive for BHV-1 and BHV-4 specific antibodies by ELISA respectively and 74 (52.9%) of tested samples had neutralizing antibodies to BVDV in virus neutralization test. Furthermore, the results also showed that 11.4% of the samples (16/140) had antibody against all of BHV-4, BHV-1 and BVDV. From our results, BHV-1, BHV-4 and BVDV may be responsible for causing abortions and BVDV seroprevalece in tested animals may be indicative for the presence of the persistently infected animals in Kars pasture. The control of abortions caused by viral infections vaccinations should be practiced before the gestation time of cattle.
