The Study Was Conducted In The Organized Dairy Farm For Sub Clinical Mastitis And Its Impact On Chemical Composition Of Milk. California Mastitis Test, Electrical Conductivity And Somatic Cell Count Were Used For Detection Of Subclinical Mastitis And Ultrasonic Ekomilk Analyzer Was Used To Analyze Chemical Composition Of Milk. A Total Of 160 Quarter Milk Samples Collected From 40 Jersey Crossbred Cows Were Examined And Overall Prevalence Of 40% And 17.48% Was Observed For Subclinical Mastitis At Cow And Quarter Level, Respectively. The Study Showed That Chemical Components Of Milk Samples Such As Fat (3.37 ± 0.33 %), Solid Not Fat (7.82 ± 0.20 %), Total Solids (11.19 ± 0.40 %), Protein (3.15 ± 0.06%) And Lactose (4.67 ± 0.06 %) Contents Of The Subclinical Mastitis Milk Was Less Than The Normal Milk. Electrical Conductivity (5.87 ± 0.21 Ms/cm) And Somatic Cell Score (scs = Log2 (scc/100,000) + 3) (3.34 ± 0.01) Of Affected Milk Was Significantly Higher Than Normal Milk. It Was Observed That The Increase In Scs Negatively Influenced The Composition Of Milk In Dairy Cows. Further, It Was Observed That Incidence Of Subclinical Mastitis Increased With The Age And Lactation Number Of The Animal.
