Abstract:
The present study was designed to evaluate the effect of four estrus synchronization protocols on reproductive performance in barbari goats. Total 40 goats were selected and divided into 4 groups of 10 animals each. The treatment protocols in different groups include, Group I: Two injection of PGF2α with 11 days apart, Group II: Two injection of PGF2α with 11 days apart along with eCG injection 48 hours before administration of 2nd PGF2α injection, Group III: Vaginal sponges impregnated with progesterone was inserted into vagina for 11 days and single PGF2α injection at the time of sponge removal, Group IV: Vaginal sponge for 11 days with eCG injection on 9th day and single PGF2α injection at the time of sponge removal. The estrus response rate, induction time & duration of estrus, conception rate, kidding rate, fecundity rate, prolificacy rate, sponge retention and vaginitis rate were estimated in different treatment groups. The results of the present study revealed that the reproductive performance was higher in the group treated with intra vaginal progesterone sponge along with eCG+ PGF2α as compared to other treatment groups.
Highlights
- Induction time of estrus was significantly low in the estrus synchronization protocol having intravaginal sponge plus eCG with PG.
