In this experiment Pearson correlation coefficients were calculated between linear type traits and stayability of Czech Fleckvieh cows. The observed correlations were r =?0.04 for stature, r =?0.08 for muscularity, r=?0.14 for rump angle, r=?0.03 for rump width, r=?0.01 for rear legs set and r=?0.18 for foot angle. The following correlations were found for udder traits: r=0.18 for fore udder, r=0.12 for rear udder, r=0.16 for central ligament, r=?0.06 for teat placement, r=0.06 for teat length and r=0.18 for udder depth. Udder traits can be used for predicting the longevity of cows.
