Abstract
In the present investigation, milk samples from 56 clinical and 379 apparently normal goats were examined. Staphaurous was isolated from 52 percent of clinical cases. The other organisms isolated were, starph. Epidermidis, str, agalactiae, C.pyogenes, K.pneumoniae, Esch. Coli, Ent.aerogenes and P.aeruginosa. The samples examined from apparently normal goats revealed an incidence of 47 percent subclinical mastitis. Mastaid Test conducted on milk samples from apparently normal goats revealed that this test was 96.5 percent efficient in detecting subclinical mastitis. From the somatic cell counts performed on milk samples, it was observed that normal milk (CMT Zero) had a mean cell count of 0.9 lakhs per ml. The cell counts of 5 to 10 lakhs (CMT + ) represented subclinical mastitis. When a comparative study was conducted study was conducted with mastrid test, whiteside test and tcepol mastitic test it was observed that mastaid reagent could only be relied upon in detecting subclinical mastitis. Chloramphenicol was found to be the drug of choice in goat mastitis, as evidenced by the in vitro sensitivity tests. Erythromycin, Ampicillin, Terramycin and Pencillin were moderately efficient. Results of the treatment with sensitive drugs on 40 selected clinical cases have been discussed.
