The examination of stained blood smears from pyretic cross bred cows (3041) and buffaloes (3122) of Eastern Haryana from July, 2003 to June 2010 revealed significantly higher infection in cows (27.88%) than buffaloes (0.6%). The pyretic cross-bred cows had Theileria annulata (22.88%) Trypanosoma evansi (0.33%), Babesia bigemina (3.22%) and Anaplasma marginale (1.45%) whereas buffaloes (3122) had T.evansi (0.32%) and B. bigemina (0.32%) only. Percentage of pyretic cows detected positive for T.annulata, B.bigemina and A.marginale was high from 2006-09 (27.6 to 32.8%), 2007 – 09 (3.91 to 5.60%) and 2006-10 (0.87 to 2.7s0%), respectively. Seasonwise T.annulata and B.bigemina were recorded in higher percentage of cross-bred cows during summer (9.7 and 1.6%) and rainy season (9.2 and 1.1%). Lower values of haemoglobin, packed cell volume and total erythrocytic counts in haemoprotozoan infected cross bred cows revealed anemia. The results of these observations suggest proper diagnosis of pyretic animals before undertaking therapeutic measures.
