Název v původním jazyce

Cryopreserved, in vitro produced embryos from genetically valuable cows with reproductive disorders

Popis výsledku v původním jazyce

Embryos were derived from genetically valuable cows of different breeds excluded for reproductive disorders. Oocytes were collected in the growth phase or the other phases of follicular development after the estrus of cows was (define donors) or was not(undefine donors) synchronized. Embryos were prepared and frozen by standard protocol. After thawing, they were transferred to synchronized heifers. The both, the mean numbers of usable oocytes, transferable and freezable embryos collected per donor andthe mean rates of usable oocytes, transferable and freezable embryos were significantly higher in the defined than the undefined donors. After transfer of 41 embryos, 20 heifers became pregnant. It can be concluded that the higher number of oocytes can be recovered in the growth phase compared with other phases of follicular development; greater development of these oocytes resulted in more transferable and freezable embryos and transfer of frozen-thawed embryos yielded a 48.6 % pregnanc
