Somaticell? as a screening method for somatic cell count from bovine milk

摘要

The objectives of the present study were to evaluate the correlation between electronic somatic cell count (eSCC) and Somaticell? under different milk somatic cell count (SCC) conditions and to different mastitis pathogens and calculate the, sensitivity, specificity and predictive values of Somaticell? using different SCC limits established by different countries. Three-hundred and forty milk samples were aseptically collected according to the California Mastitis Test (CMT) result. The Somaticell? and eSCC were carried out in all milk samples. The correlation between Somaticell? test results and electronic counts was determined according to the CMT, isolated pathogen and eSCC score. According to the SCC scores established, 26.5% milk samples showed score 1 (69-166x103cells mL-1), 26.8% score 2 (167-418x103cells mL-1), 27.4% score 3 (419-760x103cells mL-1) and 19.4% score 4 (761 to 1,970x103cells mL-1). According to Spearmann correlation test, eSCC and Somaticell? had a positive correlation (P
