The Effects of Season and Lactation Number on the Composition and Quality Of Holstein Cattle Raw Milk

The 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
