In Vitro Production Of Goat Embryo In Bangladesh- A Short Review With Special Reference To Black Bengal Goat

In vitro production (IVP) of embryo is one of the most propitious assisted reproductive technology (ART) adopted in modern livestock industry. Bangladesh, a developing country has been working enormously to adopt this technique in various livestock species. As goat is the most promising small ruminant of this country, several research work has been ongoing to adopt IVP on this species, more specifically on Black Bengal goat (BBg), the only recognized breed of Bangladesh. For conservation, improvisation and increased production of this goat breed ART like IVP is a major pre requisite. IVP of embryos usually includes retrieval of oocytes from the ovarian follicles, in vitro maturation (IVM), sperm capacitation, in vitro fertilization (IVF) of oocytes and in vitro culture (IVC) of presumptive zygotes to morula or blastocyst stage. Research showed, the source and quality of the ovary, oocyte and the cumulus-oocyte-complexes (COCs), semen quality, oocyte recovery time and procedure, culture condition, supplements and the subsequent factors plays a critical role in the maturation and subsequent development of the embryo which can be varied from lab too lab upon researcher’s choice. A short review on the IVP of goat embryos is discussed here in the context of recent encouraging data which will aid future researchers aiming at successful embryo production of BBg in vitro.
