The aim of the study was to estimate genetic parameters for conformation traits and to analyze relations between the conformation of Czech Pied first-calvers and their production characteristics. Totally 16,148 cows were linearly scored and type classified. The highest hE(2) were estimated for body capacity (hE(2)= 0.45), muscularity (hE(2)=0.41), stature (hE(2)=0.38), pin width (hE(2)=0.35) and body depth (hE(2)=0.34). The highest hE(2) for descriptive traits of udder were estimated for rear udder conformation (hE(2)=0.35), fore teat placement (hE(2)=0.33), median suspensory (hE(2)=0.27) and teat length (hE(2)=0.27). Heritability estimates for general conformation characteristics ranged from 0.24 to 0.45. A significant positive relationship was observed between percentage of protein in milk and body capacity (rg=0.37) an muscularity (rg=0.32).
