The research was carried out on seven bull daughters, which were kept in the same shed, under the same welfare conditions, and there were simultaneously analyzed blood serum biochemical mean indicators, the results obtained were compared to the physiological norm: protein from 82.60 ± 6.59 g LE-1 to 85.05 ± 6.01 g LE-1; urea from 8.87 ± 3.60 mmol LE-1 to 12.84 ± 3.55 mmol L-1 and phosphorus from 2.53 ± 0.61 mmol LE-1 to 2.85 ± 0.70 mmol LE-1. The correlation coefficients for each bull daughters group are different. There is a significant negative correlation between the milk yield for 305 days and blood serum glucose r = -0.358, the fat content of milk and blood serum protein r = -0.370 (P is less than 0.01), but between the fat content of milk and glucose content of the blood serum there is a positive correlation r = 0.287 (P is less than 0.05).
