Abstract:
Fertility response following fixed time insemination was studied in 18 Sirohi goats, randomly divided into 3 groups. All animals except control group were implanted progesterone impregnated vaginal sponge for a period of 10 days. Animals of group-I Additionally, intramuscular injection of 300IU eCG on day 9 (one day before implant removal) and 125µg of the PGF2α analogue cloprostenol at the time of implant removal (day 10). Oestrus detection and timed artificial insemination was performed at 48 hours after last injection of PGF2α analogue cloprostenol. Animals of group-II were implanted progesterone impregnated vaginal sponge for a period of 10 days followed by intramuscular injection of 125µg PGF2α analogue cloprostenol at time of sponge removal on day 10, followed by oestrus detection and timed artificial insemination at 48 hours. Animals of group–III were kept as control and injected 1 ml sterile normal saline intramuscularly on corresponding days of treatment groups and timed artificial insemination (TAI) was performed similar to treatment groups.
The fertility response using different progesterone based synchronization protocols revealed highest oestrus synchronization, induction and conception rate in group-I (100, 100 and 83.33%) respectively with interval to oestrus of 24-36 hours after removal of the sponge, whereas, lower oestrus synchronization, induction and conception rate in group-II (83.33, 66.67 and 66.67%), and group-III (16.67, 16.67 and 16.67%) was recorded interval to oestrus in group-I (24-36 hours after sponge removal) was lower as compared to group-II and group-III (36-48 hours after sponge removal).
