Question

Write a short note on multiple ovulation embryo transfer technology.

Answer 1

Hint: Multiple Ovulation Embryo Transfer (MOET), a conventional embryo flush, is the most common procedure used in advanced cattle breeding. 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.

Complete answer:
In this question, we have asked about MOET. As we already mentioned, MOET is multiple ovulation embryo transfer. The name itself is defining the process, in this process, multiple ovum is released in one cycle and then these ovum fertilized and the embryo is transferred to another animal. This is generally done in cattle. We give the hormones like follicle stimulating hormones and prostaglandins to female cattle with desirable genes so that multiple ovum is released in one cycle. This process is called superovulation. The process of superovulation takes almost 5 weeks. The eggs are then fertilized by artificial insemination. From the result of fertilization, embryos are formed. These embryos are collected on the 7th day without any surgery and then transferred to other cattle or surrogate mothers so that embryos can grow inside them. So, the only function of 1st cattle is to release ovum and the pregnancy is completed in other cattle. Normally a cow produces one calf in a year but by MOET it is possible to produce more than one offspring from the genetically fit cows.

Note:
The advantages of MOET are:
 Reproductive rate of the animals increase
The entire procedure can be done in a farm.
No surgery is required.
The embryos can be frozen and can be used later.
