Abstract
Totally 370 serum samples from the four districts of North-Eastern region of
Karnataka were screened for IBR seroprevalence viz., Vijaypura, Bidar, Kalaburgi and
Yadgir districts using ELISA kit .Overall prevalence of IBR in this region irrespective of
farming system was found to be 36.49%.In buffaloes less than five years of age overall
prevalence was found to be 8.92% and it was 27.57% in buffaloes more than five years
age. Among the buffaloes having the history of abortion overall prevalence was found to
be 9.19%. District-wise seroprevalence was highest in Bidar district (51.09%) followed
by Kalaburgi (43.48%),Vijaypura (35.87%) and lowest in Yadgir district (15.96%).
Among the different farming sector higher prevalence was found in organized farming
sector. Between the districts the prevalence of IBR was highest in Bidar district organized
sector compared to other districts. Among the unorganized sector highest seroprevalence
was in Kalaburgi district. No significant difference of seroprevalence of IBR was seen
among less than five years age buffaloes in different districts but lowest seroprevalence
was in Yadgir district. Seroprevalence of IBR in more than five years age was more
compared to less than five years age group. Highest prevalence of IBR in more than five
years age group was seen in Bidar district. Prevalence of IBR in buffaloes with history of
abortion was highest in Bidar district and no significant difference was seen in
seroprevalence of IBR between districts. The higher prevalence of IBR in organized
farming sector may be attributed to poor managemental practices observed in this region
during the study.
