“…In cattle, blastocyst production increased when the interval between the last dose of FSH and COC collection was delayed (48 hr vs. 33 hr [Blondin, Bousquet, Twagiramungu, Barnes, & Sirard, ). However, in a recent study in wood bison, the proportion of blastocysts produced was not affected by extending the FSH interval period by 24 hr (Cervantes et al, ). Ovarian response in wood bison needs further investigation with respect to seasonality, handling stress and other unknown factors to understand any issue related to poor ovarian response.…”

“…Embryo production via techniques involving in vivo and in vitro fertilization is necessary to deploy a genome biobank and has been used to a limited extent in the preservation of some endangered wildlife species (Comizzoli, Mermillod, & Mauget, ; Loskutoff, Bartel, Meintjes, Godke, & Schiewe, ). Beginning with the bovine model (Adams & Singh, ), we have conducted a series of studies in an effort to develop these reproductive technologies for use in bison (Cervantes, Palomino, Anzar, Mapletoft, & Adams, ; Cervantes et al, , ; Palomino, Cervantes, & Adams, ; Palomino, McCorkell, Woodbury, & Adams, ; Palomino et al, , ; Toosi et al, ). An added complexity with North American bison is seasonality.…”

Two experiments were done using a two-by-two design to determine the effects of season and superstimulatory protocol on embryo production in wood bison. In Experiment 1 (in vivo-derived embryos), ovarian superstimulation was induced in female bison during the ovulatory and anovulatory seasons with either two or three doses of FSH given every-other-day (FSH × 2 vs. FSH × 3, respectively). Bison were given hCG to induce ovulation, inseminated 12 and 24 hr after hCG, and embryos were collected 8 days after hCG (n = 10 bison/group). In Experiment 2 (in vitro embryo production), ovarian superstimulation was induced in female bison during the ovulatory and anovulatory seasons with two doses of FSH, and in vivo maturation of the cumulus-oocyte complexes (COC) was induced with hCG at either 48 or 72 hr after the last dose of FSH. COC were collected 34 hr after hCG, and expanded COC were used for in vitro fertilization and culture. In Experiment 1, the number of follicles ≥9 mm, the proportion of follicles that ovulated, the number of CL, and the total number of ova/embryos collected did not differ between seasons or treatment groups, but the number of transferable embryos was greater (p < .05) in the ovulatory season. In Experiment 2, no differences were detected between seasons or treatment groups for any end point. The number of transferable embryos produced per bison was greatest (p < .05) using in vitro fertilization and was unaffected by season (1.5 ± 0.2 and 1.1 ± 0.3 during anovulatory and ovulatory seasons, respectively), in contrast to in vivo embryo production which was affected by season (0.1 ± 0.01 and 0.7 ± 0.2 during anovulatory and ovulatory seasons, respectively). Results demonstrate that transferable embryos can be produced throughout the year in wood bison by both in vivo and in vitro techniques, but the efficiency of embryo production of in vivo-derived embryos is significantly lower during the anovulatory season.

“…This is because of the restrictive laws protecting this species across Europe, especially in Poland (Krasińska, Krasiński, Perzanowski, & Olech, ). It should be emphasized that access to oocytes in wood and plain American bison species is higher (Cervantes et al., ; Krishnakumar et al., ; Thundathil et al., ) than in Wisent, from which oocytes can be collected from only 2–5 females per year. Culled females and males are also usually old, so the competence of gametes is also low.…”

“…Studies aimed at implementation of this procedure for the Bison genus have been conducted for many years. Heretofore, only three cases resulted in production of in vitro bison embryos using oocytes matured completely in vitro (Cervantes et al., ; Krishnakumar, Whiteside, Elkin, & Thundathil, ; Thundathil et al., ). In 2016, researchers from Saskatchewan University in Canada announced the birth of four wood bison calves after transfer to recipients of one frozen embryo and three fresh embryos; however, these were derived from oocytes matured in vivo (http://www.usask.ca).…”

Wisent, or European bison (Bison bonasus), is listed as "vulnerable" on the IUCN Red List of Threatened Species and is therefore protected by international law. For the first time, a Wisent embryo has been obtained in vitro. This procedure creates a new opportunity to protect and increase Wisent reproductive potential and thereby opens new possibilities for the establishment of a controlled and broad reserve of the gene pool.

“…In an ideal situation, the best strategy for obtaining good-quality oocytes is to collect them in vivo. To accomplish this, the follicular aspiration method using laparoscopy (Thongphakdee et al, 2017), laparotomy (Berlinguer et al, 2008) and transvaginal ultrasound (Cervantes et al, 2017) techniques can be used (Table 1). Nevertheless, few species have been sufficiently studied for this type of manipulation to be safe and efficient (Hildebrandt et al, 2018).…”

Wild ungulates are of fundamental importance for balancing ecosystems, as well as being the species of economic interest. Increasing concern over the accelerated population reduction of these species has resulted in the development of assisted reproduction techniques, such as in vitro fertilization (IVF), as a tool for conservation and multiplication. In the present scenario, IVF protocols were developed based on the methodologies used for domestic ungulates. Nevertheless, owing to the physiological and reproductive differences among the species, several factors associated with IVF and its relationship with the characteristics of the species of interest require clarification. In vitro conditions for the collection and selection of female and male gametes, oocyte maturation, sperm capacitation, co-incubation of gametes, and embryonic development can influence IVF results. Therefore, the present review considers the main advances in the methodologies already used for wild ungulates, emphasizing the strategies for improving the protocols to obtain better efficiency rates. Additionally, we discuss the conditions of each IVF stage, with emphasis on aspects related to in vitro manipulation and comparability with the protocols for domestic ungulates.
