dc.description.abstractThe aim of this study was to determine the Somatic Cell Count of raw milk which obtained from Holstein-Frisian dairy cow milk and determine the effects of season and lactation number on the composition and quality of raw milk. Milk samples were collected monthly during one year from 30 Holstein-Frisian dairy cow. The fresh milk samples were collected in 250 ml flasks and delivered to laboratory at a temperature of 4 degrees C cold chain and analyzed. The fat, protein, lactose, dry matter rate and Somatic Cell Count of raw milk samples were automatically performed with Bentley Merkim Nexgen Series Model 1 device. While no significant differences were found in % fat, % protein, % dry matter and average daily milk according to lactation number (p>0.05), The differences determined in %lactose and SCC (p<0.01) were significant. The highest SCC content of raw milk was observed in the 4th lactation (928.30 +/- 117.93) and lowest in 1st lactation (356.47 +/- 50.55). According to the seasons the SCC observed from highest to lowest were in winter 1003.88 +/- 83.53, in spring 877.63 +/- 97.43, in autumn 575.81 +/- 63.97 and in summer 212.36 +/- 17.94. Negative correlation coefficients observed between SCC and daily milk yield of all lactations, however the correlation coefficient in first lactation was not significant different from 0. The study indicated, that were negative relationships between SCC and daily milk yield, except in first lactation and summer. It has been observed that all groups of SCC are above the threshold value specified in the Turkish Food Codex Raw Milk notification, except 1st lactation and the summer.
