Ten gilts each received a total of 20\u00a0mg of EB or EDP on Day 10 or EB on Day 10 and 14 to induce pseudopregnancy (Day 0\u00a0=\u00a0onset of estrus).

The embryos were collected 7\u00a0days after the administration of hCG, and assessed for embryo yield and their developmental stages. All protocols resulted in good embryo yield (9.8\u201313.2 embryos in average), and the embryos showed average ability to develop to the expanded blastocyst stage (3.29\u20134.03 as developmental scores) without any significant differences among the protocols.
