Abstract
A total of 296 quarter milk samples were collected from 74 buffaloes of different
age groups, parity and stage of lactation from two adjoining districts Tumkur and
Chitradurga of Karnataka state. Data regarding the pattern of milking and type of flooring
of the shed was also collected during sampling. Overall occurrence of bubaline clinical
and subclinical mastitis was 10.13% and 63.15% respectively. Occurrence of clinical
mastitis was higher in age group of 9-11 years whereas, occurrence of SCM was higher in
3-5 year age group. Occurrence of bubaline mastitis was higher in higher parity
buffaloes. Occurrence of bubaline mastitis was higher in early lactation. Occurrence of
bubaline mastitis was higher in hindquarters but there was no significant difference in
occurrence when compared to quarters. Bubaline mastitis was higher in buffaloes which
are housed in kaccha (soil) flooring and milked by knuckling method. In the present
study high correlation coefficient was seen between SCC and NAGase activity and low
correlation coefficient was seen between BTB with EC and CMT. CMT was highly
sensitive and NAGase activity measurement was highly specific test. EC and BTB may
not be useful as a single diagnostic technique. There was increase in protein% and
decrease in fat% and SNF% in SCM milk samples. Coagulase-negative Staphylococci
were the most prevalent organisms isolated from subclinical mastitis. Bacterial isolates
were highly sensitive to Chloramphenicol and least sensitive to Penicillin-G. SCM cases
need to be treated with vitamin E and selenium and trisodium citrate to prevent infection. The
supplementation of vitamin E and selenium or trisodium citrate were found to be more effective,
economical and safe for animals. Further, milk was also safe for human consumption.
