Embryo transfer (ET) is an important reproductive biotechnology used to accelerate genetic improvement and enhance reproductive efficiency in cattle. However, the success of embryo transfer programs is influenced by several factors related to embryo characteristics, recipient physiology, management practices, and environmental conditions. The present study evaluated the effects of various recipient- and embryo related factors on pregnancy rate following embryo transfer in crossbred dairy cattle. A total of 131 crossbred dairy heifers and cows were used as recipients under field conditions during winter and summer seasons. The animals were aged between 17 and 28 months, with body condition scores ranging from 2.5 to 3.5 and body weights between 310 and 430 kg. Recipient animals were synchronized using two hormonal protocols (CIDR and GnRH + PGF₂α). Pregnancy diagnosis was performed approximately 60 days after embryo transfer using transrectal ultrasonography. The overall pregnancy rate observed in this study was 24.4% (32/131). Recipients synchronized using the CIDR protocol showed significantly higher pregnancy rates (37.0%) compared with the GnRH + PGF₂α protocol (17.6%) (P < 0.05).These findings indicate that synchronization protocol play important roles in embryo transfer success under field conditions.
