Abstract: Gir cows in an organized livestock farm in Jamdoli, Jaipur were confirmed with the clinical signs such as anorexia for more than three months, gradual reduction in milk yield, mild lymphadenopathy, conjunctivitis and mild nasal discharge. Blood smear examination of these animals confirmed Theileria annulata infection. Hematological studies in Gir cows revealed significant low RBC count, Hb content, lymphocytes count. Bio-chemical studies in these cows revealed significant high values of, total protein, total bilirubin, globulin, & phosphorus with insignificant low values of Albumin: Globulin ratio & Calcium level. The restricted macro-schizont replication in theileria infected lymphoid tissues, more white blood cell production in native cattle due to less pronounced bone marrow suppression activities, more activated macrophages, low production of pro-inflammatory cytokines, removal of causative organisms and the restoration of tissue homeostasis, were the attributed factors associated with less pronounced clinical and hemato-biochemical parameter variations in theileria infected native Gir cows.
