PREVALENCE OF MASTITIS IN NILI RAVI BUFFALO HERD AT LIVESTOCK EXPERIMENT STATION BHUNIKEY, PATTOKI

Abstract

Mastitis is one of the major and keen parameter for quality and quantity of milk
production. The recent study was conducted to estimate the occurrence rate of mastitis in four different
seasons of the year and its therapeutic cure in Llivestock Experiment Station Nili Ravi Bhunikey. For
this purpose, the total of 1188 milk samples were screened for mastitis through California Mastitis
Test. Out of total 1188 milk samples, the prevalence rate of mastitis was 9.7% (27/279) in winter, 14%
(40/286) in spring , 7.2% (23/320) in summer and 6% (18/303) in autumn respectively. An overall
prevalence rate of mastitis was 9 %( 108/1188).The screened positive samples were subjected to
culture on culture media. Seven antibiotics were selected for the fortitude of antibiotic sensitivity
against the cultured organisms. Antibiotics used in current research were Gentamicin, Enrofloxacin,
Amoxycillin, Norfloxacin, Tylosin, Oxytetracycline and Chloramphenicol. The efficacy of the
different antibiotics was checked by the configuration of the zone of inhibition. The outcome showed
that the incidence of mastitis was greater in spring and lower in autumn. From selected antibiotics,
Enrofloxacin and Gentamycine have resulted in more effective against the cultured organism.
