Rezumat

The article discusses the results of the fetus development in Holstein heifers, received from sexed semen. Absolute and average daily live weight gain in calves is compared. Correlation of the growth intensity and development of heifers with the intensity of the fetus development has been determined. Average live weight at birth, absolute and average daily gain from birth to calving periods of growth, as well as the duration of the intrauterine development of their offspring, were almost the same for animals of 1 and 2 groups. The growth rate and development of heifers positively correlated with the rate of development of their fetuses. To improve the replacement of a herd of cows on dairy farms it is recommended to use sexed sperm for insemination of heifers.
