This experiment was carried out in an experimental facility without transportation of the embryos.

Seven estrous-cycling D, L, and LW gilts 9–10 months old and 5 D, L, and LW sows of the first to second parity were used as recipients for Ns-ET of V/W embryos warmed and diluted in conventional method, and the effects of asynchrony between the donor and recipient estrous cycles on pregnancy, farrowing, and the survival rates of embryos to term were evaluated. In this experiment, 14–19 vitrified embryos from a few donors were warmed for one trial. A total of 192 embryos were used for this experiment. The estrous cycle of the recipients was controlled by hormone treatment as described above. Ns-ET to asynchronous recipients was conducted on Day 5 (n = 4) or 6 (n = 8) after hCG administration (i.e., when the estrous cycles of the recipients were asynchronous with a 2- or 1-day delay, respectively, relative to those of the donor: designated as the 2- and 1-day groups, respectively).

These data appeared in Table 1; however, the authors confirmed that the data of Table 1 are correct, and no correction is necessary.

This experiment was conducted to assess the production of piglets by Ns-ET under field conditions at commercial swine farms using vitrified, transported, and warmed (V/T/W) porcine embryos. The embryos derived from D, W, and L donors were vitrified at Aichi Agricultural Research Center or Saga Prefectural Livestock Experiment Station and transported to four commercial swine farms located 20–70 km apart from each experimental facility in Aichi or Saga Prefecture using a LN2 container (SC4/2 V; Chart biomedical Co., Ball Ground, GA, USA) on the day of Ns-ET. A total of 16 LW sows of the first to sixth parity were used as recipients. Ns-ET was conducted at 6 days after injection of hCG in a small pen or farrowing crate kept under acceptable hygienic conditions. Warming and dilution of vitrified embryos were conducted in a one-step method, and a total of 11–20 vitrified embryos from each donor in one or two devices were warmed for one trial. The period of time from insertion to removal of the catheter was recorded. A total of 251 embryos were used for this experiment.
