摘要：

In this study, the relationships between Somatic Cell Counts (SCC), in milk samples obtained from 110 cows in 2 different barns and udder traits classified by using objective and subjective measures, were investigated. Stage of lactation was determined to have effect on SCC and log SCC and the residuals of objective measures were calculated. Squared multiple correlation (R(2)) values, calculated from residuals were found to be small for objective measures (0.08-0.17). In step 1, in which multiple linear coefficients were calculated, teat diameter, fore udder height and rear udder height values were demonstrated to be statistically significant (p<0.05); whereas in the last stage, although, teat diameter and fore teat height values were determined to be statistically significant (p<0.05), rear teat height was demonstrated to be insignificant and was removed from the model. Teat end shape was determined to have effect on log SCC, whereas udder form and localization of the udder lobe were found to be ineffective.
