The aim was to evaluate whether pregnancy rates could be improved by randomly injecting recipient mares with flunixin meglumine (FM; Banamine®, Schering-Plough, São Paulo, Brazil) on the day of embryo transfer combined or not with long-acting proge

The importance of serum progesterone (P4) during the first weeks of pregnancy to reduce the embryo mortality in cattle herds has been demonstrated (Mann and Lamming 2001 Reproduction 121, 175-180). Studies show that a P4 peak at the beginning of preg

Inconsistency of the superovulatory responses of donor hinds has been a general feature of all red deer MOET programs (Asher GW et al. 2000 Anim. Reprod. Sci. 59, 61-70). The development of the techniques has been by trial and error as there is usual

Progestagen-releasing devices are commonly used for fixed-time artificial insemination and fixed-time embryo transfer (FTET). The aim of this study was to evaluate the efficacy of a new progesterone-releasing intravaginal device made of poly(3-hydrox

Pregnancy rates after the transfer of bovine IVP embryos are lower than that achieved after the transfer of MOET embryos. One reason may be that the relatively defined IVC (SOFaaBSA) culture system used in vitro is suboptimal for embryo development.

When cumulus–oocyte complexes (COC) are cultured with follicle-stimulating hormone (FSH), germinal vesicle breakdown (GVBD) occurs and is transcriptionally dependent. In mice, expression of mRNA for nuclear receptor subfamily 4, member 1 (Nr4A1), a

Intracytoplasmic sperm injection (ICSI) provides a possible remedy to produce high numbers of monospermic zygotes. However, the efficiency of ICSI in pigs is low, mainly due to a failure of oocyte activation and low incidence of sperm head decondensa
