Abstract: The number of somatic cells in milk is the main health indicators of the mammary gland. With the development of subclinical mastitis occur changes in the composition and physico-chemical parameters of milk. The aim of this study was to investigate the changes in pH, lactose, protein, total solids (TS), the freezing point depression (FPD), phosphorus (P) and calcium (Ca) milk in a state of subclinical mastitis and whether these parameters to be used as indicators of inflammation. The study included 40 animals with 80 milk halves of different ages. The results showed an statistically significant increase of pH values (P<0.001) and TS (P<0.05) with subclinical mastitis and lower lactose, phosphorus and calcium (P<0.001).
