Diagnosis of Sub-Clinical Mastitis (SCM) in Organised Dairy Herds.

The study describes diagnosis of sub-clinical mastitis in cows in organized dairy farms under different phases of lactation. The diagnosis of sub-clinical mastitis (SCM) was made using cow side field tests i.e. California mastitis test (CMT) and Somatic cell count (SCC) and bacterial isolation. The predominant causative agents isolated from milk of cows with SCM were Staphylococcus aureus, E.coli, Pseudomonas aeruginosa, Streptococcus spp. and Proteus spp. where Staphylococcus aureus was found highly pathogenic followed by E. coli, Pseudomonas aeruginosa, Streptococcus spp. and Proteus spp. causing SCM in cows.
