The present study was conducted to assess the prevalence of anaplasmosis in cattle farms. The data were collected from 120 sample cattle owners selected from 6 blocks in 3 districts of North east zone of Tamil Nadu viz. Kancheepuram, Tiruvannamalai and Vellore districts. The data was collected from cattle farms with the incidence of anaplasmosis during the month of December 2013 to March 2014. A total of 60 anaplasmosis affected cattle farms were studied. The results of the study indicated that there was a significant association between age, sex, breed, season, acaricide application and prevalence. The prevalence was high in animals at the age group of 3 to 5 years (36.59 percent), females (29.71 percent), crossbred Holstein-Friesian cattle (32.38 percent), summer season (35.23 percent) and acaricide-not-used animals (33.62 percent). Hence, care should be taken on the affected animal instantly to avoid these losses. Thus, the losses due to these diseases in cattle could be prevented by application of scientific management practices and control over these predisposing factors. Further lack of knowledge to manage the diseased animals had resulted in avoidable economic losses. Thus, the appropriate policy suggestions have to be made to control of anaplasmosis in cattle and minimise the economic losses due to this disease.
