The investigations conducted on three groups of dairy cows with mammites, found at different stages of lactation, pointed out the correlations between the number of somatic cells from milk and some of its constituents, represented by the content in total dry matter, total proteins, lipids, lactose, casein and chlorides. Analysing the number of somatic cells and the milk constituents, we found the presence of the positive ( + 0.91 ; + 0.96 ) and significant correlations ( p¡Ü 0.05 ) between the number of somatic cells and the evolution of the content in chlorides from milk in all the three groups of cows, which indicates that once with the increase in the number of somatic cells, the number of chlorides has proportionally increased, and the negative (-0.89; -0.96) and significant correlations (p¡Ü0.05) between the number of somatic cells and the milk production, the content in lactose (-0.91; -0.96 and p¡Ü 0.05), casein (-0.87; -0.97 and p¡Ü 0.05), total proteins (-0.82; -0.93 and p¡Ü 0.05) and the fat content(-0.65; -0.91 and p¡Ü 0.05).
