Embryo Transfer :: essays research papers

Embryo transfer is the process of taking fertilized embryos from one animal and inserting them into another. This is really useful today in cattle, because now it is economically feasible and it allows the manufacturing business a greater number of offspring from one cow with in demand(predicate) traits. The process starts normally by artificially inseminating the cow. Exactly seven years subsequent, the womb is flushed, and the embryos and ova. Next, the embryos will be isolated. The embryos are therefore inserted into the recipient cow.unnaturally inseminating the cow is the preferred way to fertilize the eggs in the sponsor cow. The cow should be inseminated at least tierce times at intervals of twelve hours, to insure fertilization. In preparation for AI, a shot of follicle-stimulating hormone (Follicle Stimulating Hormone) should be given to the cow to super-ovulate her. This causes more eggs to redact from the ovaries, allowing more embryos. Seven days after the cow i s inseminated the third time, her uterus should be flushed.Before flushing the cow, her posterior should be cleaned up as some(prenominal) as possible. After this is complete, an instrument known as the introducer is inserted into the vagina. The instrument is frequently like a long syringe with a plunger sack by means of the center. The vet then will push his hand done the anus and guide the introducer along the cervix. The instrument is pushed through the cervix and into the uterus. Once it reaches the uterus, the plunger is pulled out and a catheter is inserted into the uterus, against the uterine horn, through the center of the introducer. The cuff, a scurvy balloon type object, is inflated in the cows uterus, and a sodium based phosphate is released for lubrication. It is then pumped back through the introducer, and filtered by an embryo filter. The liquid caught by the filter is then examined to find the number of good embryos. At this stage, the sex can even be determi ned. They are graded, then placed in straws or frozen for later use. Implanting the embryos into the cow is done just like artificial insemination. The straw is inserted in the vagina, while the vets hand guides the straw through the cervix, and then released into the uterus. Success of the process can be determined one to three months later through palpation. The embryos can be stored safely at 37 degrees Fahrenheit for six-eight hours, however implanting as soon as possible is recommended for the vanquish results.
