dc.description.abstract
In horses, prostaglandin E2 (PGE2) is produced by embryos around Day 5 post-ovulation; PGE2 functions directly at the oviduct promoting embryo transport into the uterus. Non-surgical collection of horse embryos for cryopreservation is recommended at Day 6.5–7 post-ovulation. It was proposed that misoprostol administered orally will hasten oviductal transport of horse embryos. In Experiment 1 (n = 15) there was comparison of time of embryo recovery (Day 6 and 6.5 post-ovulation) from mares administered misoprostol (Day 5 and 5.5) orally to that of untreated mares. On Day 6, embryo collections were attempted; if no embryo was collected, there was a second attempt on Day 6.5. In Experiment 2, (n = 16) misoprostol treatment was initiated on Day 4.5; there was the first embryo collection attempt on Day 5.5, followed by Day 6 and 6.5 if no embryo was collected. Blood samples were collected at 12 h intervals on Day 4.5 or 5, to Day 6.5. In Experiment 1, on days 6 and 6.5, respectively, there was collection of seven and one of a total of eight embryos detected at the time of collection per group (P = 1). In Experiment 2, 12 embryos were collected during 15 cycles with there being a total of three, two, and one collected from mares of both groups on Day 5.5, 6, and 6.5 post-ovulation, respectively (P = 1). Serum progesterone concentrations were not different (P ≥ 0.05). In conclusion, misoprostol, when administered orally, does not hasten oviductal transport of horse embryos.
