Summary
The present study was designed to determine animal’s wise and quarter wise prevalence rate and associated microorganisms in sub clinical mastitis in buffaloes of swat area. The samples were collected from apparently mastitic free 800 quarters, of 200 buffaloes. The samples were subjected to surf field mastitis test (SFMT) and the data obtained was analyzed by Chi-Square test. Animal wise prevalence rate of subclinical mastitis was recorded higher in village, Kula Deer (50%), followed by Bela (48%), Takhta Band (42%) and Totano Bandai (38%) of swat district. Out of 183 positive samples the quarter wise infection was recorded as: In front quarters 58 (31.25%) right and 40 (22.00%) left teats were found positive for sub-clinical mastitis, similarly in hind quarters, 64 (35.05%) right and 21 (12.00%) left teats were also found positive. A relatively higher prevalence of bacterial mastitis was noted in hind quarters as compared to front quarters and in the same way higher prevalence in right side than left side of quarters in buffaloes. Nine bacterial species were isolated and identified from positive milk samples. The descending order of bacterial species detected was: Staphylococcus aureus 35.51%, Escherichia coli 16.39%, Streptococcus agalactea 14.75%, Streptococcus dysgalactae 7.83%, Proteus vulgaris 4.37, Citrobacter sp. 4.18%, Streptococcus uberis 3.82%, Bacillus cereus 3.27% and Pseudomonas aeruginosa 1.63%.
