Oestrus synchronization protocols used in the mare are efficacious in the jenny. The interval to oestrus and ovulation were 9.0±0.9 and 14.5±1.7 days respectively following progestrone/estradiol treatment, and 4.5±0.9 and 10.4±1.8 days respectively, for double prostaglandin (PG)F2a 15 days apart (Blanchard et al, 1999). The percentage of jennies ovulating between 6 and 10 days is 62.5% following Altrenogest/PG F2α (8 days) and 76.3% following double PG F2α system (Vendramini et al, 1997). Devices of vaginal delivery of progesterone such as CIDR have been used successfully.
