Abstract:
The present work has been carried out to study the epidemiology of Bovine theileriosis in and around Hassan District of Karnataka State. Retrospective study was carried out over a period of three years and prospective study for a period of one year. Prevalence of Bovine theileriosis was found to be 4.05 percent and 17.69 percent in retrospective and prospective study, respectively. There was a statistically significant increase in percent prevalence in prospective study compared to retrospective study. Present study revealed statistical significant (p≤0.05) difference with respect to gender-wise prevalence. Female animals suffer more from Bovine theileriosis compared to male animals. Among positive animals, percent prevalence was more in female animals (87.80%) compared to male animals (12.20%). In both retrospective and prospective study, breed-wise prevalence was more in HF crossbred cattle followed by Jersey crossbred and Non-descript cattle. It was noticed that there was no statistical significant difference with respect to breed-wise prevalence although crossbred animals are more prone to diseases than indigenous. There was no statistical significant difference with respect to age-wise prevalence indicating the Bovine theileriosis can occur in any age group whenever animals are exposed to causative agents. In retrospective study, prevalence of Bovine theileriosis was highest in post monsoon followed by summer, monsoon and least in winter season. Moreover in prospective study same trend was noticed with high prevalence in post monsoon, summer, monsoon and least in winter season. When season-wise prevalence of Bovine theileriosis was analyzed statistically, there was no significant difference among different season in both retrospective and prospective study indicating Bovine theileriosis can occur throughout the year depending on other predisposing factors.
