The influence of Multiple Ovulation and Nonsurgical Embryo Transfer on pregnancy rate in Holstein Friesian Heifers

Nawfal Khalaf Mutlak.


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

Key words: Multiple ovulation and embryo transfer, estrus synchronization, pregnancy rate, superovulation
