About 150 milk samples were collected from goats in and around Bidar, Karnataka and screened for SCM by California Mastitis Test and Electrical conductivity. The percentage prevalence of SCM based on CMT and EC, was 30.00 and 48.66 per cent respectively. The parity wise per cent prevalence of SCM in goats was increased with increase in the parity and was highest during seventh parity compared to primiparous goats. Lactation stage wise per cent prevalence of SCM in goats was highest during early and mid lactation and least in late lactation. Results of haematology indicated that increase in total leucocyte count and granulocyte count and decrease in lymphocyte count in SCM affected goats. Results of biochemical study revealed no significant difference between healthy and SCM goats. Culture and isolation of samples revealed Staphylococcal spp in majority, followed by Streptococus, Clostridia, Mixed culture and Escherichia. Treatment of SCM goats with Ceftizoxime was found to be more efficient with 80% cure rate than that of Marbofloxacin with 60% cure rate.
