Abstract: The study was undertaken to know the haemato-biochemical alteration in blood smear positive and blood smear negative Theileria spp. in crossbred cows in Khandala, Phaltan, Lonand and Pandharpur taluka of Satara and Solapur district. 103 cross bred cattle selected randomly irrespective of age, breed, sex, physiological status, farming system etc. and blood samples were collected in EDTA and plain vials. Samples were screened for the presence of Theileria spp. schizonts by microscopy and further analysed to estimate haemato–biochemical parameters. There was 7/103 (6.79%) cattles were positive for Theileria spp. by microscopic examination of blood smear. Blood smear positive group showed statistically highly significant lymphocytosis (p<0.01), while Blood smear negative group showed statistically highly significant neutrophilia (p<0.01) (Table 1). Difference in monocyte count of these groups was also statistically significant (p<0.01), however individual animal values of monocyte were within normal physiological limit in both the groups. Hb, PCV, TEC and TLC were relatively lower in blood smear positive animals but the difference was statistically non-significant. The finding suggestive of low-grade chronic infection (carrier state). Neutrophilia in blood smear negative animals was not reflected in TLC.
