Abstract
Present study was carried with an objective of finding prevalence of subclinical mastitis (SCM) and effect
on milk quality in cross-bred (CB) and desi-dairy cattle (Zebu, Nondescript-ND) of Hassan district, Karnataka, India.
Diagnosis was based on cow side tests - California mastitis test, and mastrip which substantiated by Direct Microscopic Somatic Cell Count (DMSCC). Upon evaluation of 150 CB and 40 ND cattle,65 (43%) of CB cattle and 5 (12%) of
ND cattle were found positive for SCM on California mastitis test and mastrip test. Overall, 70 of 190 animals (37%)
were positive for SCM. The DMSCC enumeration found 0.3-0.5 million SCC per mL for normal and 0.6-1.5 million
SCC per mL for SCM positive milk. The milk pH, fat and Solids Not Fat (SNF) exhibited slight variance between
normal and SCM positive animals. The prevalence was more common in hygiene and welfare compromised animals.
