  Abstract
  Time-lapse cultivation allows the processing of the maximum amount of information on early embryo development, including such morphological disorders that are not observed in the traditional assessment of embryo cleavage at certain time intervals. The time-lapse technology was used by the authors to monitor the development of pre-implantation cattle embryos obtained from unstimulated ovaries. It was shown that the temporal and morphological characteristics of the first and three subsequent embryo divisions determine compaction probability and the embryo reaching the blastocyst stage. Embryos whose development did not fit into these time parameters did not form a blastocyst and stopped at different stages of development.
