The Effect of Somatic Cell Count on Milk Urea Nitrogen and Milk Composition [Somatik hücre sayi{dotless}si{dotless}ni{dotless}n süt üre nitrojen i̇le süt kompozisyonuna olan etkisi]

The objective of this study was to evaluate the effects of somatic cell count on milk urea nitrogen and milk composition. according to their somatic cell count,the holstein cows (n=30) were divided into two groups. in the experiment,somatic cell count (1. group: x<268.000 cell/ml; 2. group: x>268.000 cell/ml) were affected milk fat,milk lactose,solids-non-fat,density significantly (p<0.05); but were not affected milk urea nitrogen,milk protein,milk urea,total solid,acidity,free fatty acids,citric acid,milk caseine and freezing point depression (p>0.05). a significant correlation (r =0.209,p=0.026) was recorded between somatic cell count and milk fat; a significant correlation (r =-0.183,p=0.050) was recorded between somatic cell count and solids non fat; a significant correlation (r =-0.196,p=0.037) was recorded between somatic cell count and lactose and a significant correlation (r =-0.281,p=0.002) was recorded between somatic cell count and density.
