Abstract: 427 milk samples were collected from 30 Holstein dairy cows in the farm of Huhhot suburb during May to October in 2005.The milk samples were segregated and categorized into five different SCC(somatic cell counts)groups.The concentrations of chloride,potassium,sodium,total calcium,free calcium ion in milk and SCC were determined respectively.The results showed that significant positive correlation exists among concentrations of chloride,sodium and the SCC(p<0.001);the correlation between free calcium and SCC is negative(p<0.05);while total calcium and potassium are poorly correlatied(p>0.05).The correlation between the contents of SCC,chloride,potassium,sodium,total calcium,free calcium ion in milk and month is poor (p>0.05).The concentration between chloride and total calcium has significant positive correlation(p<0.001);The positive correlation exists between the chlorideion and sodiumion between the total calcium and free calcium and between the sodiumion and total calcium(p<0.05).The rest is of correlation(p>0.05).

Key words: somatic cell count, milk ion, correlation
