Abstract:
The present study was conducted to know the efficacy of best estrus synchronization protocols on reproductive performance in goats. Estrus synchronization is valuable reproductive and manage mental technique to breed the goats. Total 100 does were selected in the present study. All the goats were grouped into 5 groups of 20 each. The treatment protocols are control (group – 1), injecting PGF2α with 12 days apart (group-2), vaginal sponges which is treated with progesterone was impregnated into vagina for 12 days (group – 3), vaginal sponge for 12 days with PMSG at the time of removal of sponge (group – 4) and vaginal sponge + PMSG + GnRH at time of breeding (group – 5). All the animals in different groups were analysed for reproductive performance based on Pregnancy rate, Kidding rate, Litter size and Twinning rate. This present study results reveled that, the reproductive performance is high in group – 5 when compared with groups 2 and control.
