The efficiency of medroxyprogesterone acetate (MAP) and fluorogestone acetate (FGA) sponges with or without PGF2alpha (cloprostenol) for synchronizing oestrous in non-lactating does was investigated during the natural breeding season. Does were treated for 11 days with MAP or FGA sponges, and they all also received intramuscular injections of PMSG. Some of the does were injected cloprostenol. There were significant differences between groups FGA/PMSG/PGF2alpha and MAP/PMSG in terms of the duration of induced oestrous and between groups FGA/PMSG/PGF2alpha and FGA/PMSG in terms of oestrous response at the first 12+/-6 h. The use of MAP/PMSG and FGA/PMSG intravaginal progestagen treatments with or without cloprostenol are equally efficient in synchronizing estrous in non-lactating hair goats during the natural breeding season.
