Research was conducted on 1943 promaparas cows of Polish Holstein-Friesian breed of black--white variety maintained in 25 herds in Greater Poland (Wielkopolska). An assessment of cows' conformation was done using a GLOBAL MAP mating programme. Assessed cows obtained mean notes close to biological optimum established for particular conformation traits. However, considerable differentiation of evaluations was observed within these traits. Calculated coeficients of phenotypic correlation point mostly positive and low relations between evaluations of particular conformation traits. Also indices of phenotypic correlation between evaluations of conformation traits and milk performance of cows low and positive were in most cases.
