Black-White cows imported from Holland are characterized by the correct body build. For the 305 days of lactation milk yield averaged 7795 kg with 4,41% fat and 3,35% protein content The average milk yield as FCM per 100 kg of body weight was 1294 kg. Ratio of milk, fat and protein yield obtained at first 100 days of lactation was respectively: 36,2; 36,7 and 33,8% as compared to the 305 days lactation Indices: the ratio of protein to fat content (SBT), the difference between fat and protein content in milk (RTB) and the Sanders index were respectively: 0,77; 1,06 and 254. Phenotypic correlation coefficients between milk performance traits and body measurements were low in values and quite often negative. The only strong relation for the 305 days of lactation was reported between milk protein content and the depth of chest (r = - 0,39; P 0,01).
