The dairy industry is facing a great set back due to high prevalence and incidence of mastitis in milch animals. The aim of this study was to identify the factors discriminating between ‘clinical and subclinical mastitis, ‘clinical and chronic mastitis’ and ‘subclinical and chronic mastitis’ using linear discriminant function analysis. The present study was conducted at the Large Animal Clinic of Madras Veterinary College (MVC) Hospital, Chennai. Out of two hundred and eighty milch animals examined during the study period, sixty cows were affected by mastitis. Results revealed that while discriminating clinical and subclinical mastitis, the variables named breed of the animal, hand pre-washing prior to milking and udder washing before milking discriminated 0.748, 0.413 and 0.644 times respectively towards subclinical mastitis. Stage of lactation and provision of bedding material discriminated 0.462 and 0.547 times respectively towards clinical mastitis. A total of seven variables was found to be significant for discriminating between clinical and chronic mastitis. Fishers linear discriminant functions obtained might be used to discriminate the further cases of mastitis to be presented in Madras Veterinary College hospital.
