^aThe least square means are the adjusted means of the EBVs for the SCS for bulls which are grouped by genotype for each SNP and calculated for the respective lactation (over all, first, second or third lactations). SEM standard error of the mean.

^{b, c}Means (within a line) without a common superscript letter differ from each other at the 5% level of significance.
