Multiple Ovulation And Embryo Transfer
Embryo transfer et is an effective method of increasing the reproduction rate of individuals or groups of animals.
Multiple ovulation and embryo transfer. All female animals are capable of producing far more eggs than they ever need over their lifetime. In argentina red deer breeding is an alternative farming activity that has developed over the last few years enhanced by the introduction of semen embryos and animals from foreign countries. Currently there are two methods utilized commercially for embryo production in cattle et programs. The cow is inseminated and embryos are then flushed from the cow s uterus the following week.
In current moet protocols donor females are superovulated through treatment with follicle stimulating hormone fsh in order to stimulate the release of multiple oocytes at the time of ovulation. It involves a 5 week superovulation program resulting in several eggs being released from the donor cow as opposed to one during a natural heat. At the onset of estrus or heat cycle under the influence of follicular stimulating hormone only one ovum is mature as such the cow gives one calf. This is an introduction to the multiple ovulation and embryo transfer moet procedure.
It is the traditional method of embryo production and is practised in cattle.

Moet multiple ovulation embryo transfer technology is the technique in which multiple eggs are fertilized in an animal and the embryo is collected on the 7th day without any surgery. Camels are induced ovulators thus require hormonal treatment to induce ovulation and control the follicular cycles which is the main reason why protocols used in other domestic animal species cannot be directly.
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 animals in which situations the goals may vary. Embryo transfer can be done at day two or day three or later. Possibilities for increased rates of genetic change in dairy cattle through embryo transfer and embryo splitting are examined using the multiple ovulation and embryo transfer systems previously. Form high milk producing cow in a lifetime calving get 5 or 6 calves.
Multiple ovulation embryo transfer moet a conventional embryo flush is the most common procedure used in advanced cattle breeding.
