摘要

Embryo transfer technology (ETT) helps in the dissemination of best germplasm of both male and female whereas artificial insemination (Al) disseminates only male genotype. The aim of present study is to evaluate the variables affecting pregnancy ratefollowing non-surgical embryo transfer in crossbred and indigenous cattle under farm condition. A total of 48 frozen embryos were transferred into as many recipients which resulted in overall 20.83 per cent pregnancy rate. The study revealed that transfer of embryos into anterior one third of uterine horn resulted in significantly (P < 0.05) higher pregnancy rate (34.62%) compared to the posterior two third of uterine horn (4.55%). The results indicated that the site of embryo deposition in uterine hornhas significant influence on the pregnancy rate in cattle.
