A study was conducted to record the prevalence of Haemoprotozoan infections in bovines of Shimoga region for a period of 1 year from April 2012 to March 2013. A total of 300 blood samples were examined for the presence of haemoprotozoan parasites, of which 215 from cattle and 85 from buffaloes were examined by Giemsa staining technique. Out of 300 blood samples examined, 130 (43.3 %) were found positive for Haemoprotozoan infections. Out of 215 cattle blood samples examined, 62 (28.8 %) were positive for Theileria annulata, 27 (12.5 %) were harbored Babesia bigemina, 15 (6.9 %) were found positive for Trypanosoma evansi and 06 (2.7 %) samples showed Anaplasma marginale. Among 85 buffalo samples examined, 11 (12.9 %) were showed Theileria spp, 04 (4.7 %) found positive for B. bigemina, 03 (3.5 %) were found positive for T. evansi and 02 (2.3 %) were positive for A. marginale. Among haemoprotozoan parasites, the highest prevalence was observed with T. annulata followed by B. bigemina and T. evansi infection. The lowest prevalence was observed with A. marginale infection.
