• Description:
  The aim of the study was to determine the effectiveness of the use of ReSynch schemes forsynchronization of estrus in Holstein cows. To synchronize estrus, GnRH preparations(Ovarelin) and PGF2α (Enzaprost) were used based on the ReSynch protocol. Theinvestigated Holstein cows reared at the Promin farm of the Mykolaiv region in Ukraine. Usingthe ReSynch scheme, the synchronization of estrus were performed in the two experimentalgroups: Holstein cow with normal ovaries and uterus (n = 15), Holstein cow with cysts andbilateral ovarian hypofunctions (n = 15), and the control group (n = 15). When using ReSynchestrus synchronization schemes in the first experimental group, the fertility rate was 88 %,which is 33 % (p<0.05) higher compared to the control, in the second – 70 %, which is 15 %higher relative to the control group. The service period for the first experimental group ofcows was 97±6.2 days, for the second experimental group was 110.4±5.5 days, while in thecontrol group it was 117.4±6.4 days. The insemination index of the first experimental groupwas 2.2, in the second experimental group was 2.6, and in the control group was 2.9. Theindicators of reproducible qualities of Holstein cows in the control group are significantlylower than those in both experimental groups when using ReSynch synchronization schemes.
