Cell sorting is an important part of the sperm sexing process. The objective of this study was to compare the efficiency of in vitro embryo production using sexed frozen–thawed bull sperm sorted with 2 types of cell sorter. Ejaculates from 2 Bos ta

It has been reported that a preincubation of the reconstructed oocytes prior to activation treatment might enhance the efficiency of nuclear reprogramming after somatic cell nuclear transfer in many species. The objectives of this study were to evalu

Beef heifers that conceive early during their first breeding season calve earlier, wean heavier calves, and tend to continue doing so throughout the rest of their reproductive lives. Otherwise, under extensively managed systems in Southern Brazil, on

A population of bulls with 1.7% 56-day non-return rate were found to share a 1386 kb segment of homozygosity (Pausch et al. 2014 PLoS Genet. 10, e1004044). That study identified a nonsense mutation in the transmembrane protein 95 (TMEM95)-encoding ge

The aim of this work was to evaluate the effect of repeated ovum pickup (OPU) on buffalo welfare. The OPU was carried out as previously described (Neglia et al. 2003 Theriogenology 59, 1123–1130) twice per week on 11 buffalo cows at 121 ± 15 days

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

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

The inability of stallion sperm to capacitate in an in vitro setting has limited many equine assisted reproductive technologies such as gamete intrafallopian transfer (GIFT) and IVF. These experiments were conducted to develop methods for artificiall
