“…Few attempts have been made so far to explore the feasibility of ARTs in accidentally dead wild ruminants. Successful oocytes recovery, IVM and IVF have been reported in nilgai ( Boselaphus tragocamelus ) (Mahesh et al., 2011), in chousingha (Tetracerus quadricornis ) (Brahmasani et al., 2013), in blesbok ( Damaliscus pygargus phillipsi ) (Brad et al, 2004; Winger, Damiani, Loskutoff, 1997), addax antelope ( Addax nasomaculatus ) (Hall‐Woods et al, 1999), blackbuck ( Antilope cervicapra ) (Keller, Chapman, Westhusin, Drew, & Kraemer, 1999; Rao et al, 2010), black wildebeest ( Connochaetes gnou ) (Brad et al, 2004), dorcas gazelle ( Gazella dorcas ) (Roldan et al, 2005) and springbok ( Antidorcas marsupialis ) (Krisher et al, 2006). Post‐mortem‐derived oocytes have been matured in vitro and developed to morulae⁄blastocysts following IVF in klipspringer (Raphael et al, 1991), Kudu "Tragelaphus strepsiceros" and impala "Aepyceros melampus" (Loskutoff, Bartels, Meintjes, Godke & Schiewe, 1995), blackbuck (Keller et al, 1999) and springbok (Krisher et al, 2006).…”

In recent decades, concern about nature conservation has grown rapidly as a consequence of accelerating rates of natural habitat loss, fragmentation and degradation that have resulted in the extinction of several species (Haddad et al., 2015). Assisted reproductive techniques (ARTs) and genetic rescue banks (GRBs) are useful tools to cope with fragmentation of habitats and loss of genetic variability (Zachos, 2011). In ungulates, ARTs' application could permit a more rapid expansion of populations than natural breeding (Andrabi &

“…Rao et al (2010) evaluated the competence of mature oocytes from Indian blackbuck for embryonic development using parthenogenetic activation and obtained 58.0% cleavage and 13.0% blastocysts. In wild deer species, artificial activation was used to assess the competence of oocytes collected immediately or 12 h after animal death, with no significant effect observed on embryonic development (Brahmasani et al, 2013).…”

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.

“…In general, follicular size, the oocyte collection method, and the culture environment are factors that can affect the quality of mature oocytes, and different responses to these factors can be observed in wild mammals. In some cervid species, Brahmasani et al (2013) observed that low maturation rates could probably be caused by slicing. In this method, non-competent oocytes can be recovered, as the technique can result in the recovery of structures of small diameter follicles (Rho et al , 2001).…”

“…For red deer ( Cervus elaphus ), electrical activation before chemical activation with ionomycin and 6-DMAP was efficient for the production of clone embryos (32–44%), obtaining genetically healthy calves (Berg et al , 2007). Nevertheless, the same protocol resulted in a low developmental rate (5.7%) of activated oocytes in swamp deer and 0.0% embryos in spotted deer, sambar deer, and brow-antlered deer after oocyte parthenogenetic activation (Brahmasani et al , 2013). Blackbuck ( Antilope cervicapra ) oocytes activated with ionomycin and 6-DMAP resulted in 58% cleaved embryos and 13% blastocysts (Rao et al , 2010).…”

SummaryIntraspecific and interspecific cloning via somatic cell nuclear transfer (iSCNT) is a biotechnique with great possibilities for wild mammals because it allows the maintenance of biodiversity by recovering species, nuclear reprogramming for the production of pluripotency-induced cells, and studies related to embryonic development. Nevertheless, many areas in cloning, especially those associated with wild mammals, are still in question because of the difficulty in obtaining cytoplasmic donor cells (or cytoplasts). Conversely, donor cell nuclei (or karyoplasts) are widely obtained from the skin of living or post-mortem individuals and often maintained in somatic cell banks. Moreover, the creation of karyoplast–cytoplast complexes by fusion followed by activation and embryo development is one of the most difficult steps that requires further clarification to avoid genetic failures. Although difficult, cloning different species, such as wild carnivores and ungulates, can be successful via iSCNT with embryo development and the birth of offspring. Thus, novel research in the area that contributes to the conservation of biodiversity and knowledge of the physiology of species continues. The present review presents the failures and successes that occurred with the application of the technique in wild mammals, with the goal of helping future work on cloning via iSCNT.
