Abstract

The objective of this study was to determine the relationship between udder and teat characteristics and somatic cell count (SCC). A total of 749 (73.1%) milk samples from 1,024 quarters of 259 Holstein cows contained less than 200,000 somatic cells/ml, while 132 (12.9%) quarters contained more than 500,000 somatic cells/ml. Prior to data analysis, somatic cell counts were transformed to natural logarithm. The mean SCS {$log_e(SCS/10^3)$} of milk samples from the front quarters was lower than milk samples from the rear quarters. The highest SCS was observed from cows with the step-shaped udder and the pear-shaped teats, respectively. Increased SCS was observed from cows with large teat diameter, short teat length, short distance between the teat tip to floor (p<0.05) and with increase in parity, respectively.
