Abstract
The present study was carried out to evaluate the effect of embryo quality, and number of embryos recovered per flush from donors on the pregnancy rates in dromedary camels. Donors (n=51)were flushed at day 8-9 after breeding with 1000 mlcommercial flushing media prior transfer to synchronized recipients (n= 457)using transvaginal technique. Pregnancy was diagnosed at Day 18-19, 30 and 60 post-transfer to recipients at rate of 55.1%, 47.9%and 43.4%, respectively. Transferring transparent embryos resulted in significantly high pregnancy rates at Day 18-19 and 60 (P<0.001) and Day 30 (P<0.0001) compared with those of semitransparent and dark embryos. Transferring of spherical embryos resulted in significantly highpregnancy rates at Day 30 (58.6%; P<0.003) and Day 60 (52.7%; P< 0.001) compared to folded embryos. Neither the size of embryo nor number of recovered embryos hadsignificant effect on pregnancy rates after transfer.In conclusion, higher pregnancy rates up to Day 60 after transfer could be obtained if transparent and spherical embryos are implemented in embryo transfer protocol in dromedary camels.
