EVALUATION OF CHEMICAL AND ELECTROLYTE COMPONENTS OF MILK IN SUBCLINICAL MASTITIS IN HOLSTEIN X HARYANA CATTLE

Abstract

The present investigation was carried out to investigate whether the chemical and electrolyte components of milk can be used as an indicator to detect subclinical mastitis in Holstein X Haryana cows. The bacterial cultural examination revealed 32 cows comprising 34 quarters are SCM positive. SCM positive and negative samples were estimated for electrical conductivity (EC) and pH with respective meters, sodium (Na+) and potassium (K+) with Flame photometer and chloride (Cl-) by titremetric method. The result demonstrated statistically significant (p<0.01) increase in EC, Na+ and Cl- and decrease in K+. After studying the correlation coefficient among the milk components and comparing them with a Gold standard (Log10 SCC) separately in normal and infected milk it was found that Na+, Cl- and K+ are the indicators of SCM in the present study.
