In recent decades, many significant improvements have taken place accompanying different assisted reproductive biotechnologies like estrous synchronization, artificial insemination, superovulation, cloning, embryo recovery and its transfer, in vitro fertilization, cryopreservation and transgenesis. Among these technologies, embryo transfer has achieved a great importance having produced numerous offspring from a genetically superior female. After the first successful transfer of mammalian embryos in 1890, it was approximately 60 years before significant progress became quite noticeable in the basic technology of embryo transfer in cattle. In embryo transfer process, embryo is collected from superior quality donor cattle and transferred to other recipient female cattle for complete development unless the gestation accomplishes. This technology involves the selection of donor and recipient animals, management for better breeding evaluation, embryo production, collection and transfer of embryo within a narrow window of suitable estrous time. In cattle, embryo transfer technology is widely used to amplify the reproductive rates of genetically improved superior females, planed mating, twinning, disease control, better pregnancy rate in repeat breeder cattle and increment of production of farm and reproductive rates. However, embryo transfer is widely used owing to its potential benefits. Hormonal protocol and synchronization improvements increase the embryo production rates via superovulation. This review details the embryo production technique, transfer of embryo from donor to recipient and the factor that are necessary for transfer of embryo from donor to recipient for production of offspring. Previously limited information existing regarding embryo transfer and its significance in farm animals therefore, in future this review might be helpful in improving the reproductive potential of farm animals.
