Description
| - Embryos were derived from genetically highly valuable cows of three breeds excluded from breeding for reproductive disorders. Oocytes were collected either at the growth phase or at other phases of follicular development after estrous cycle of cows was or was not synchronized. Significantly higher (P<0.01) number of usable oocytes (20.4 vs 11.7 per donor) were collected at the growth phase than at other phases of follicular development from infertile high performance cows. Significantly higher (P<0.01) development of these oocytes (20.9 % vs 9.0 %) resulted in more transferable and freezable embryos compared with those recovered at other phases (4.3 vs 1.0 and 3.2 vs 0.8 per donor). Transfer of frozen-thawed embryos yielded a 48.6 % pregnancy rate in recipients.

- Od geneticky cenných krav tří plemen, vyřazených z chovu pro poruchy v reprodukci, byla připravena embrya in vitro. Oocyty byly získány buď v růstové fázi nebo v ostatních fázích folikulárního vývoje potom, co říje krav byla nebo nebyla synchronizována. Signifikantně vyšší (P<0.01) počet použitelných oocytů (20,4 vs 11,7 na donorku) byl získán v růstové fázi než v ostatních fázích folikulárního vývoje z neplodných geneticky cenných krav. Signifikantně vyšší (P<0.01) vývoj těchto oocytů (20,9 % vs 9,0 %) umožnil získat více přenosuschopných i zmrazitelných embryí ve srovnání s oocyty získanými v ostatních fázích (4,3 vs 1.0 and 3,2 vs 0,8 na donorku) folikulárního vývoje.Transfer zmrazených a rozmrazených embryí do recipientek umožnil získat 48,6 % graviditu.
