Abstract: Few crossbred cows from an organized livestock farm in Jamdoli, Jaipur were reported with the clinical signs of anorexia for a period of 2 weeks, high fever, low milk yield, conjunctivitis and profuse nasal discharge. Clinical examinations of the above animals confirmed the above clinical signs in addition to lymphadenopathy, and blood smear examination of the animals confirmed Theileria annulata infection in 6 crossbred cows. The farms having 26 crossbred cows were screened for theileria infection since six animals were in the above clinical signs for more than 2 weeks period. Blood smear examination revealed Theileria infection. Hence these cows were evaluated for their hemato-biochemical parameters for T. annulata infection. In these crossbred cows significant low level of RBC count, Hb content, WBC, PLT, lymphocytes, granulocytes, and significant high levels of MCH were observed. Bio-chemical studies in crossbred cows revealed significant high values of ALT, AST values, total bilirubin, total protein, & globulin and insignificant low level of A: G ratio & calcium by the T. annulata infection in comparison with normal healthy crossbred cow values. The risk factors associated for hemato-biochemical changes in the T. annulata infected crossbred cows are discussed for further clinical management of the affected cows.
