Results of tests presented in the paper constitute an attempt to estimate milk performance of primipara cows, progeny of Black-and-White dams and three-breed (Jersey x Holstein-Friesian x Red Danish) sires. The crossbreds distinguished themselves with higher milk performance and higher fat and protein content as compared with their contemporaries of the Black-and-White breed. The body weight of cows approximates to 470 kg
