Studies on Protein in Abnormal Milk

Normal milk and various abnormal milks, i.e., mastitic milk, Alcohol test positive milk, drying off-secretions and colostrum were investigated by polarography, based upon the so-called Brdicka’s filtrate reaction. Mastitic milk including subclinical mastitic milk, drying-off secretions and colostrum gave the higher protein double wave than that of normal milk. However, any relation was not observed between alcohol sensitivity and wave height. Polarographic filtrate reaction is not specific for mastitic milk but for lactation stage or healthy conditions of cow.
