The present study was aimed to have an in-depth study on haemato-biochemical alterations in mastitis cows along with compositional changes in mastitis milk. There was an overall incidence of 41.88 % of mastitis screened on basis of clinical signs, SCC and MCMT with 77.56 % subclinical mastitis and 22.54 % of clinical mastitis. Hematology of mastitis cows revealed anemia with significant decrease in Hb, TEC and PCV, leucocytosis with nutrophilia, eosinophilia and lymphopaenia. Significant increase in Total Protein, AST, Na+ and K+ concentrations and a significant decrease in Glucose, Ca+ and Phosphorous concentrations was seen in affected cows. Significant (p<0.05) increase in pH, Whey Protein, Na+ and electrical conductivity and a significant (p<0.05) decrease in specific Gravity, acidity, Fat, SNF and total protein value observed mastitis milk. Tetracycline was found as the most prevalent antibiotic residues. Histopathology of the representative tissue sample revealed the presence of ductal haemorrhages with adjacent fibrotic proliferation, polypoid fibrotic growth projecting into the lumen of teat canal, fibrosis along with inflammatory cells filled in ductal areas. Data generated during the study envisages understanding the disease severity for remedial therapy and assessing detoriation in the milk quality for food safety.
