This study was conducted to ascertain infectious etiologies of bovine abortions in Northern Western Himalayan region of Himachal Pradesh. Overall, 16.77% (27/161) serum samples were positive for antibodies to at least one bovine abortion-causing pathogen. The overall prevalence was highest for BHV-1 (8.07%) followed by Chlamydia (3.11%), B. abortus (2.48%), T. gondii (1.86%), Leptospira (0.62%), and C. albicans (0.62%). None of the tested samples was positive for C. burnetii and Aspergillus. The occurrence of bovine abortions was higher (51.85%) in the second trimester of gestation followed by the third (44.44%) and first trimester (3.70%). In comparison to previous studies, we recorded a lower prevalence of infectious etiologies of bovine abortions. Hence, it is important to investigate the role of the non- infectious etiologies of bovine abortions such as hormonal (progesterone insufficiency), nutritional (negative energy balance, feedstuff containing anti-nutritional factors) and miscellaneous causes including poor animal management, toxin infestation, and twin pregnancies.
