STUDIES ON MASTITIS IN BUFFALOES CAUSED BY BACTERIAL SPECIES

Studies on the clinical mastitis in buffaloes caused by bacterial species was carried-out. Total 213 buffaloes were examined, the overall prevalence of clinical mastitis was recorded in 79.34% (169) buffaloes caused by bacterial infection, while 20.65% (44) was recorded as free from any bacterial infection. Similarly, 852 milk samples were collected from 213 animals and investigated, 56.80% (484) was found positive while 43.19% (368) was detected as negative. A relatively higher prevalence of bacterial mastitis was recorded in hind quarters against front quarters. In hind quarters, the higher prevalence of infection was recorded in left hind quarters (28.92%), while lower (26.44%) in right hind quarters. Furthermore, a higher prevalence of bacterial infection was recorded in left front quarters (22.72%) while lower prevalence was observed in right front quarters (21.90%). Generally, a higher prevalence of clinical mastitis was recorded in hind quarters as compared to front quarters. On the other hand, an incidence on clinical mastitis in buffaloes during various months of the year was also investigated. The higher incidence of clinical mastitis was observed in August (65.62%) and March (65.0%) months. Similarly a variation in the incidence of clinical mastitis in buffaloes at different months was recorded during present survey.
