Bovine anaplasmosis is one of the economically important haemoprotozoan diseases in India. The disease is a major constraint in dairy industry and causes great economic losses to livestock farmers through mortality and loss of productivity. The present research work was carried out to study haemato-biochemical changes in cattle affected with anaplasmosis. A total of 66 cattle suspected for anaplasmosis were screened based on clinical signs and blood smear examination. Out of them, 22 were found positive for anaplasmosis. Out of them total 18 positive cases of anaplasmosis were selected for study. while group 1 of six healthy cattle was kept for comparison of various haemato-biochemical parameters. The haematological examination revealed that the mean±SE values of haemoglobin, packed cell volume, total erythrocytes count and mean corpuscular haemoglobin concentration (MCHC) were significantly decreased (p<0.01) in anaplasmosis affected cattle as compared to healthy cattle, However, lymphocyte and platelets count were decreased non-significantly. Furthermore, there was significant (p<0.05) increase in mean corpuscular volume (MCV), while total leucocytes count (TLC), mean corpuscular haemoglobin (MCH), neutrophils, monocytes and eosinophils increase non-significantly. The serum biochemical examinations revealed that the mean±SE values of total protein were decreased non-significantly, while albumin and A/G ratio were decreased highly significantly (p<0.01) in anaplasmosis affected cattle as compared to healthy control group. Globulin and alanine aminotranferase were increased significantly (p<0.05), whereas aspartate aminotransferase and bilirubin were increased highly significantly (p<0.01). However, serum creatinine was increased non-significantly in anaplasmosis affected cattle as compared to healthy cattle.
