The production of embryos by superovulation is often reduced in periods of heat stress. The associated reduction in the number of transferable embryos is due to reduced superovulatory response, lower fertilization rate, and reduced embryo quality. There are also reports that success of in vitro fertilization procedures is reduced during warm periods of the year. Heat stress can compromise the r...

The aim of this study was to enhance the ovulation and subsequent embryo production of equine chorionic gonadotrophin (eCG) superovulated goats by supplementing with human chorionic gonadotrophin (hCG) or gonadotrophin releasing hormone (GnRH). Thirty crossbred donor does were oestrus synchronized using controlled internal drug release (CIDR) device and superovulated using 1500 IU eCG. Then all...

Due to economical and scientific limitations, sheep embryo reproductive technologies are less commercially applied than in other animal species. However, it is very clear that, in the near future, those techniques are expected to have a central role in animal production as a consequence of genetic and reproductive demands. One drawback is that results obtained after sheep embryo cryopreservatio...

Background: The objectives of a series of studies undertaken was to improve farm animal reproductive efficiency in terms of embryo production efficiency, conception rate and litter size by immunoneutralization of inhibin in conjunction with other conventional reproductive techniques. Materials and Methods: A recombinant porcine inhibin alpha-subunit mature peptide was produced by mass scale and...
