Název v původním jazyce

In vitro production of embryos from high performance cows and development of frozen-thawed embryos after transfer: a field study

Popis výsledku v původním jazyce

Embryos were derived from genetically valuable cows excluded from breeding for reproductive disorders. Cows of Czech Siemmental, Holstein Dairy and Beef Cattle breeds were used. Oocytes were obtained either in the growth phase of the first follicular wave from cows with synchronized oestrus or in any other phases of follicular development from cows without oestrus synchronization. The embryos were prepared by a standard procedure. The embryos were frozen, thawed and transferred to synchronized recipients. More of usable oocytes it was recovered in the growth phase as compared with the other phases of follicular development. Greater development of these oocytes resulted in more embryos for transfer and cryopreservation. Transfer of frozen-thawed and fresh embryos gave a 48.8% and 55.8% pregnancy rates in recipients, respectively.
