The relationship between linear type traits and stayability of Czech Fleckvieh cows

Abstract

The relationship between linear type traits and stayability was analyzed in 34 492 Czech Fleckvieh cows. Pearson correlation coefficients were calculated between linear type traits and stayability of 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.
