The objectives of this study were to estimate the heritability (h2) of body condition score (BCS), body conformation (type) and production traits of Black-and-White cows maintained by small farmers of Eastern Poland as well as genetic (rG) and phenotypic (rP) correlations between the traits mentioned. Considered were 2012 cows with completed 305-day lactation from the years 1997-1999.The h2 estimate for BCS was 0.37. Out of 26 condition and conformation traits considered, the rP of 17 and rG of 13 traits appeared negative. The rG values ranged from -0.30 (musculature) to 0.45 (udder).
