abstract
The study was conducted to assess the prevalence of babesiosis 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 collected data were analysed by conventional percentage and average analysis, measure of disease occurrence and chi square analysis to achieve the objectives of the study. A total of 60 babesiosis affected cattle farms were studied. The results of the study indicated that the overall prevalence of babesiosis was 20.27 percent. The prevalence of babesiosis in Kancheepuram, Tiruvannamalai and Vellore districts was 18.52, 23.26 and 19.61 percent, respectively. The overall mortality and case fatality rate in babesiosis was 3.38 and 16.67 percent in babesiosis. There was a significant association between acaricide application and prevalence of babesiosis. Thus, the losses due to this 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 babesiosis in cattle and minimise the economic losses due to this disease.
