Association of somatic cell count with catalase enzyme activity in bovine bucket milk.

To investigate the relationship between somatic cell count (SCC) and catalase enzyme activity (CAT) of bovine raw milk samples from Samsun province, Turkey, bucket milk samples taken from a total of 25 smallholder farms each month were analyzed by SCC and CAT throughout a year. SCC values were determined by direct microscopic method and CAT values were obtained from the observation of enzyme activity scores. All data were statistically evaluated using SPSS. While the mean was relatively high for SCC, both SCC and CAT reached to elevated thresholds especially in 4th and 8th months. A significant correlation (r=0.623) between SCC and CAT suggests that CAT may be useful for determining bovine raw milk quality.
