Abstract:
The present investigation was carried out in the department of Animal Reproduction, Gynaecology and Obstetrics with an objective to evaluate the effect of PGFand oxytocin on the service behaviour with a scoring system of Jersey bulls. A total of 48 ejaculates, six from each bull before treatment were evaluated by routine semen analysis and other post freeze characteristics and in vitro fertility tests. Then the selected bulls (group I) injected with 25mg of PGF30 min. prior to semen collection, twice a week. The group II were administered with oxytocin 20 IU, 10 min. prior to collection twice a week. The group III animals were injected with 25mg of PGFand 20 IU oxytocin, 30 min and 10 min before collection respectively twice a week. The group IV animals didn’t receive any treatment. Further a total of 48 ejaculates i.e., six from each bull were evaluated post treatment by routine semen analysis and other in vitro fertility tests. Post treatment service behaviour index of each bull were observed during semen collection. In the PGFgroup the mean value of service behaviour indices in pre and post treatment group were found to be 1.85 ± 0.10 and 0.98 ± 0.05. The overall mean value of the service behaviour indices registered a significant higher value (P<0.01) as compared to its pre treatment counterpart, Similar value was also observed in oxytocin group followed by combined drug effect.
