Embryo transfer technology (ETT) helps in tho dissemination of best germ plasm 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 rate following non-surgical embryo transfer in
crossbred and indigenous cattle under farm condition. A total of 48 frozen embryos were transferred
into as many reciplents 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 horn has significant influence on the pregnancy
rate in cattle.
