3 Atatürk Üniversitesi Ziraat Fakültesi Zootekni Anabilim Dalı, Erzurum - In this study, it was aimed to determine Somatic Cell Count (SCC) and the factors effecting on SCC in milk samples of Brown Swiss and Holstein Friesian cows. Milk samples were collected from 501 lopes of 150 cows in two farms. SCC was determined by `direct counting method`. Log SCC increased with advancing lactation number and this was founded statistically significant (P<0.01). The cows had more log SCC in winter than those of in summer and the difference was founded statistically significant (P<0.05). The effect of lactation stage on log SCC was found to be statistically significant (P<0.05), however effects of breed and farm factors were not significant. It is concluded that the effects of all factors investigated on log SHS were significant except for factors of breed and farm, and mean SHS found in this study was higher than those of EU and Turkey limits.
