The study aimed to evaluated the reproductive performance response to short term oestrus synchronization during the transition period. One hundred and sixty-five indigenous multiparous non-lactating goats were subdivided into the following six treatment groups for oestrus synchronization: NT control Group (N= 30), Fe-21d, FGA vaginal sponge for 21days+eCG at 19 thd; FPe- 11d, FGA 11d + PGF2α and eCG at 9 th d; FPe-10d, FGA 10d+ PGF2α and eCG at 8 th d; FPe-9d, FGA 9d +PGF2α and eCG at 7 thd; PFe-5d, PGF2α at d0 + FGA 5d + eCG at 5 thd. The goats were natural mated (1 male/6 females). Fecundity rates (n. births /n. females treated x 100) were statistically higher (P<0.05) in short term FPe-9d (157.9%), FPe- 11d (115.4%), FPe-10d (111.1%) and PFe-5d (107.7%) groups compared to the NT control Group (66.7%).

Abstract
The study aimed to evaluated the reproductive performance response to short term oestrus synchronization during the transition period. One hundred and sixty-five indigenous multiparous non-lactating goats were subdivided into the following six treatment groups for oestrus synchronization: NT control Group (N= 30), Fe-21d, FGA vaginal sponge for 21days+eCG at 19 thd; FPe- 11d, FGA 11d + PGF2α and eCG at 9 th d; FPe-10d, FGA 10d+ PGF2α and eCG at 8 th d; FPe-9d, FGA 9d +PGF2α and eCG at 7 thd; PFe-5d, PGF2α at d0 + FGA 5d + eCG at 5 thd. The goats were natural mated (1 male/6 females). Fecundity rates (n. births /n. females treated x 100) were statistically higher (P<0.05) in short term FPe-9d (157.9%), FPe- 11d (115.4%), FPe-10d (111.1%) and PFe-5d (107.7%) groups compared to the NT control Group (66.7%).I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
