The objective of this work was to compare the values of milk somatic cell counts (SCC) using the Somacount 300, and two detergents for sample preparation. The equipment was calibrated using the detergent RBS 35. Forty independent milk samples were analyzed. Each sample was randomly divided into two subsamples, and each subsample was analyzed after preparation with either RBS 35 or Extram MA 01 Alkaline detergents. The correlation coefficient between the two methods was high (0.998). This finding suggests the possibility of substitution of RBS 35 for an economical alternative.
