Influence of Different Synchronization Protocols on Fertility Response in Surti Does

Abstract

This study was carried out to assess the influence of different estrus synchronization Protocols on fertility response in Surti does based
on litter size, fecundity and twining rate. Thirty does were selected and divided into five equal groups (n=6 in each). Does of G1 group
were treated with intra-vaginal progestagen sponges (IVPS) for 11 days. Does of G2 group received the same IVPS sponge for 11 days
and exposure of sexually active apronized buck during the treatment period. Does of G3 group were treated as per G1 group along
with i/m injection of PGF2α analog (125 μg, Cloprostenol) at the time of sponge removal. Does of G4 group were subjected to the buck
effect and exposed to a sexually active patronized buck for 11 days, and does of G5 group was kept as a control without any treatment
for 11 days. It was found that, none of the synchronization Protocols had significant effect on litter size, fecundity, and incidence of
multiple kid birth and sex ratio in Surti does.
