For an embryo transfer program to be effective, numerous factors need to be put in place to ensure success. Nutrition, estrous cycle control, donor and recipient management are all factors responsible for the success or failure in fertility for a given herd. Utilization of body condition score is a practical method to determine nutritional status of both recipients and donors. Prepartum nutriti...

BACKGROUND In New Zealand, embryo donation to others was approved in late 2005 and follows strict guidelines. To date, few donations have proceeded. Given the novelty of embryo donation and New Zealand's guidelines around donation, this study explores how potential recipients in New Zealand made meaning of embryo donation. METHODS Thirteen potential recipients were interviewed regarding decis...

A commercially viable cattle embryo transfer (ET) industry was established during the early 1970s. Initially, techniques for recovering and transferring cattle embryos were exclusively surgical. However, by the late 1970s, most embryos were recovered and transferred nonsurgically. Successful cryopreservation of embryos was widespread by the early 1980s, followed by the introduction of embryo sp...

conclusions we found acceptable short-term survival in both groups; however, living donor recipients continue to have better long-term patient and graft survival rates. results although there were no significant differences in one-year survival rates of patient and graft between study groups, three-years survival rates of patient and graft were significantly longer in living donor kidney transp...

The development of reproductive technologies in this species is contributing decisively to the rabbit farming and preservation genetic resources. Obtaining embryos an essential step both diffusion resources from erosion or natural disasters. In rabbits, it common for be recovered post-mortem after ovarian hyperstimulation with gonadotrophins, although quality number are variable, affecting embr...

Background: The chick embryo is a classical model to study embryonic development. However, most researchers have not studied the effect of embryonic manipulation on chick hatchability. To determine the effect of egg orientation and type of sealing film on the hatchability of cultured embryos, and to determine the fate of adulte stem cells injected into the blastoderm. Materials and Methods: Win...

Nuclear transfer is a complex multistep procedure that includes oocyte maturation, cell cycle synchronization of donor cells, enucleation, cell fusion, oocyte activation and embryo culture. Therefore, many factors are believed to contribute to the success of embryo development following nuclear transfer. Numerous attempts to improve cloning efficiency have been conducted since the birth of the ...
