Current Status of Embryo Transfer and in Vitro Embryo Production Using Ovum Pick-up in Cattle
Embryo transfer is an important technology to improve and increase the high genetic value cattle in a short period in both daily and beef industries. This manuscript discussed current status of embryo transfer technologies in Japan and the world. The conception rates of embryo transfer both in fresh and frozen embryos were stable last two decades in Japan. Therefore, embryo transfer in Japan is...
متن کاملImprovement in Bovine Embryo Production In Vitro
Bovine oocytes were matured, fertilized, and cultured FCM 199 with serum and co-culture) in vitro (IVMFC) with addition, during different phases of the procedure, of antioxidants: superoxide dismutase (SOD) and reduced glutathione (GSH). The addition of SOD (1,500 or 3,000 IU/ml) did not improve proportions of oocytes undergoing cleavage or the development of embryos to morula and blastocyst st...
متن کاملOvarian Follicular Dynamics, Ovarian Follicular Growth, Oocyte Yield, In vitro Embryo Production and Repeated Oocyte Pick Up in Thai Native Heifers Undergoing Superstimulation
The objective of this study was to compare the effectiveness of the protocols for superstimulation of follicular growth in Thai native heifers. Heifers (n = 20) were randomly divided into four groups of five heifers/group. Heifers were given a single dose by i.m. administration of 100 mg Follicle Stimulating Hormone dissolved in polyvinylpyrrolidone (FSHp) at 24 h. Ovum pick up (OPU) occurred a...
متن کاملSupplementation with small-extracellular vesicles from ovarian follicular fluid during in vitro production modulates bovine embryo development
Pregnancy success results from the interaction of multiple factors, among them are folliculogenesis and early embryonic development. Failure during these different processes can lead to difficulties in conception. Alternatives to overcome these problems are based on assisted reproductive techniques. Extracellular vesicles are cell-secreted vesicles present in different body fluids and contain b...
متن کاملBovine In vitro Embryo Production : An Overview
Dairy industry perfected the application of the first reproductive biotechnology, i.e. artificial insemination (AI) a great success story and also remains the user of embryo transfer technology (ETT). In addition, recently the researchers taking interest to embraced the field of Transvaginal Oocyte Recovery (TVOR) and in vitro production (IVEP) of embryos. IVF provides the starting point for th...
