¹These animals served as reference group for the fixed effects analysis.
²Actual trait mean values by batch, corrected for gender effects.
³Mean (All), average trait value across all batches (n=192);
⁴S, maximum significance of an individual batch compared to reference group.
⁵CV (%)-within, mean within batch coefficient of variation combined across all batches;
⁶CV%-batch; coefficient of variation among batch means.
