Morné de la Rey (born 7 February 1970) is a South African veterinary surgeon and embryo transfer specialist. [1] In 2003, he was one of a team of scientists and veterinarians from his company Embryo Plus and the Danish Agriculture Institute to clone a cow, the first animal to be cloned in Africa. [ 2 ]
Embryo transfer refers to a step in the process of assisted reproduction in which embryos are placed into the uterus of a female with the intent to establish a pregnancy.This technique - which is often used in connection with in vitro fertilization (IVF) - may be used in humans or in other animals, in which situations and goals may vary.
A small publication of Mukherjee in 1978 [19] clearly shows that Mukherjee was on the right line of thinking much before anyone else had demonstrated the successful outcome of a pregnancy following the transfer of a 8-cell frozen-thawed embryo into human subjects transferring 8-cell cryopreserved embryos. [20] [21]
The farm raises Red Sindhi cattle and Kangeyam cattle in order to "encourage pure breeding and to preserve native breeds." [7] The Farm has an embryo transfer laboratory. Embryos from Red Sindhi cows are collected by multiple ovulation and embryo transfer technology and are transferred to cross-bred recipient cows by non-surgical method.
In cattle, usually 10 or more embryos are removed from the flushing process. In order to flush the uterus, a technician will first seal off the female's cervix and add fluid, which allows the ovum to be flushed out of the uterine horns and into a cylinder for analysis.
In 1986, the first mouse was cloned in the Soviet Union from an embryo cell. [60] The first mouse from adult cells, Cumulina, was born in 1997 at the University of Hawaiʻi at Mānoa in the laboratory of Ryuzo Yanagimachi using the Honolulu technique. In 2008 Japanese scientists created a cloned mouse from a dead mouse that had been frozen for ...
The ability to freeze and subsequently thaw and transfer embryos has significantly improved the feasibility of IVF use. [23] In 1983, Alan Trounson and Linda Mohr reported the first pregnancy which used embryo cryopreservation (frozen human embryos). However, this embryo was not carried to term.
Increasing the productivity of embryo transfer and artificial insemination is economically profitable as the costs associated with veterinarian and semen services are reduced. The reduction of costs occur because vets are required for less time to do the inseminating because the period of ovulation of the herd is decreased to 2-5 days.
