Abstract EN
This study was carried out by selecting a total number of 17 Holstein Friesian cows divided intotwo main groups, the first group (4) cows as donors used to take the embryos from after artificialinsemination and the second group (13) heifers cows as recipients for embryos.
The sametechniques were used on donor and recipient cows for the purpose of hormonal preparation interms of instance synchronization, preparing recipient cows and superovulation for donor cows.
Artificial insemination were done in field, and a nonsurgical flushing procedure embryos appliedthen graded.
Donors reflected a good response to superovulation hormonal treatment.
The totalnumber of transferable embryos was 13 from four donors.
Evaluation of all embryos wasexcellent quality.
The pregnancy rate results for recipient cows was 61.5% .
This result is anacceptable as compared to previous studies due to many factors, the study aim was taking intoaccount all these factors, that can have an influence on these programs to obtain geneticallyimproved animals in a shorter time and lower costs.
