Abstract
Totally 30 indigenous goats of Gujarat were superovulated with FoUtropin-V (FSH) and Folligon (PMSG) to see the elfect of gonadotropin during two season ( breeding and non breeding ) to see the effect of season, on superovulatory response, recovery of embryos and quality of embryos. Further to this in the same study effect of onset time for superovulation, duration of SOV oestrus, intensity of superovulation, flushing time and recovery of flushing media on embryo recovery and quality of embryo was also evaluated ctitically. Excellant and good quality embryos were processed for cryopreservation to see the effect of cryopreservation on morphological changes of embryos. An attempt was also made to establish pregnancy by transfering forzen - thawed embryos. Blood samples from donor and recipients were also analysed for hormonal and biochemical parameter. The results revealed that total response was 80 % ( 24 out of 30 ) irrespective of season and treatment. Average time for onset of SOV oestrus was 33.50 ± 5.82 hours with 17.25 :h 0.98 hours as time for duration.
