Abstract:
In the present experiment 41 ewes were synchronized using progesterone sponge (CSWRI) for 12 days and inj. eCG @200 IU was given on the day of the withdrawal of progesterone sponge. Estrus incidence was observed in 80.49% ewes by the observation of symptoms up to 48 hrs. with the mean estrus onset time of 22.61±1.34hrs. A total of 16 synchronized ewes received fresh embryo transfer of 30 embryos. The conception rate, lambing percentage and gestational embryo loss was 50.00, 50.00 and 50.00 percent respectively. Total 7 lambs were born resulting 23.33% efficacy of the embryo transfer programme.
