Current post-thaw survival rates of vitrified in vitro-produced porcine blastocysts are much lower than those of other domestic species. The main reason for this is the suboptimal development of in vitro-produced porcine embryos, and the endemically

The purpose of this study was to evaluate the viability, acrosome integrity, mitochondrial activity, and fertility of frozen-thawed fowl semen using different cryoprotective agents. The experiments were carried out on 10 sexually adult roosters of th

It has been proposed that once good-quality sperm are collected, extended, and cryopreserved that the post-thaw quality will remain high regardless of the duration of storage. A previous study has suggested that there is no effect on post-thaw sperm

The aim of the present study was to assess the maturational competence and the cytoskeletal pattern of bovine oocytes reconstructed by a germinal vesicle transplantation (GVT) technique using nuclear and/or cytoplasmic components from cryopreserved G

Interspecies nuclear transfer is an important tool for studying the interaction between the cytoplasm of one cell and the donor nucleus of another (Chen et al. 2002 Biol. Reprod. 67, 637–642). The aim of this experiment was to investigate the possi

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

The aim of this experiment was to investigate the effect of day of synchrony on the pregnancy rate of recipients following the transfer of Day 7 IVF embryos. In addition, the effect of IVF embryo grade and corpus luteum (CL) grade of recipients was d

Intracytoplasmic sperm injection (ICSI) mediated transgenesis is an effective tool for transgenic animal production. However, ICSI in cattle remains inefficient. In this work, we assayed approaches to improve egfp expressing blastocysts production by
