“…However, evidence indicates that these are highly variable characteristics among individuals, but at the same time they are quite repeatable attributes within the same animal over several OPU sessions. Therefore, it is possible to predict the potential of each donor, not only in the oocyte production rate per OPU session, but also for its subsequent embryo production through this biotechnology (Gasparrini et al, 2014b).…”

Transvaginal follicular aspiration technique together with in vitro embryo production are the biotechnological alternatives currently available to support genetic improvement breeding programs in buffalo species. However, aspects related to animal management, lack of knowledge of the metabolic needs and biochemical peculiarities of gametes and embryos, as well as the reproductive physiology characteristics have hampered progress in the results. Despite the low availability of good quality oocytes collected after OPU in donors as a physiological characteristic of buffalo species, high rates of oocyte maturation, modest embryo cleavage, blastocyst production and pregnancy rates after transvaginal embryo transfer in recipients could be obtained in buffalo in vitro embryo production programs. The results of implementing an in vitro embryo production program in buffaloes in the northern region of Pará state, Brazil, and results published by other groups demonstrate the feasibility of implementing this biotechnology in the routine of breeding programs. Nevertheless, in order to achieve better and consistent results, it is necessary to deepen the knowledge on the peculiarities of reproductive biology in this specie. Selection of donor animals based on ovarian size and ovarian follicular reserve and on the rate of blastocyst production is presented as an effective alternative to increase the efficiency of the in vitro embryo production technique applied to the buffalo species.

“…In cattle, IVP efficiency varies from 42 to 50% (Costa et al, 2013;Santana et al, 2014a;. However, the efficiency is lower for sheep (26-35%) (Shirazi et al, 2012;Mara et al, 2013;Naderi et al, 2016), buffalos (15-22%) (Di Francesco et al, 2011;Kumar et al, 2012;Gasparrini et al, 2014), pigs (13-22%) (Yoshioka et al, 2012;Nguyen et al, 2015;, and goats (10-19%) (Kątska-Książkiewicz et al, 2007;Rodríguez-Dorta et al, 2007;Masudul Hoque et al, 2012). Long time research in IVP improvements certainly correlates with the high efficiency observed in cattle (Parrish, 2014), and also indicate that IVP may be potentially improved in other livestock animals if their biological requirements could be addressed.…”

Contributions of RNA-seq to improve in vitro embryo production (IVP)

et al. 2019

View full text Add to dashboard Cite

In Vitro Embryo Production (IVP) is widely used to improve the reproductive efficiency of livestock animals, however increasing the embryo development rates and pregnancy outcomes is still a challenge for some species. Thus, the lack of biological knowledge hinders developing specie-specific IVP protocols. Therefore, the contributions of RNA-seq to generate relevant biological knowledge and improve the efficiency of IVP in livestock animals are reviewed herein.

“…Novas biotecnologias da reprodução, com eficiência comprovada, já estão disponíveis como ferramenta de produção de descendentes. Dentre elas, pode-se mencionar a PIVE, cuja eficiência aumentou consideravelmente ao longo dos anos, levando a maiores taxas de produção de blastocistos (NEGLIA et al, 2003;GASPARRINI et al, 2006;GASPARRINI et al, 2014) e produção de descendentes em bubalinos (GALLI et al, 2001;HUFANA-DURAN et al, 2004;NEGLIA et al, 2004;SALIBA et al, 2011). Embora exista disponibilidade de outras biotecnologias para a produção de embriões, não se pode consentir de forma absoluta que a tecnologia de SOV não funciona/não pode ser utilizada em bubalinos.…”
