Summary: This study compared short- and long-term estrus synchronization in 16 cycling Santa Inês ewes. All ewes were submitted to the two protocols in a cross?over design resulting in replicates #1 and #2 with 16 ewes, each one. Ewes were synchronized with intravaginal sponges containing 60 mg medroxyprogesterone acetate (Progespon®, Schering Plough, São Paulo, Brazil) for 6.5 (G?6.5d) or 14.5 (G?14.5d) days, followed by a superovulation (SOV) of 4 or 3 days with decreasing doses of pFSH (Folltropin®?V, Bioniche Animal Health Canada Inc., Belleville, Canada), respectively.
