Embryo Transfer
Embryo transfer is the process of taking fertilized embryos from one animal and inserting them into another. This is very useful today in cattle, because now it is economically feasible and it allows the producer a greater number of offspring from one cow with desirable traits. The process starts normally by artificially inseminating the cow. Exactly seven days later, the uterus is flushed, and the embryos and ova. Next, the embryos will be isolated. The embryos are then inserted into the recipient cow. Artificially inseminating the cow is the preferred way to fertilize the eggs in the donor cow. The cow should be inseminated at least three times at intervals of twelve hours, to insure fertilization. In preparation for AI, a shot of FSH (Follicle Stimulating Hormone) should be given to the cow to super-ovulate her. This causes more eggs to dro
The vet then will push his hand through the anus and guide the introducer along the cervix. They are graded, then placed in straws or frozen for later use. After this is complete, an instrument known as the "introducer" is inserted into the vagina. The straw is inserted in the vagina, while the vet's 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. It is then pumped back through the introducer, and filtered by an embryo filter. The embryos can be stored safely at 37 degrees Fahrenheit for six-eight hours, however implanting as soon as possible is recommended for the best results. Even though this method was effective, it required much work and was not worth the money. The "cuff," a small balloon type object, is inflated in the cow's uterus, and a sodium based phosphate is released for lubrication. Seven days after the cow is inseminated the third time, her uterus should be flushed. The liquid caught by the filter is then examined to determine the number of good embryos. The instrument is pushed through the cervix and into the uterus. p from the ovaries, allowing more embryos. They also can be frozen and stored for long amounts of time. This is a smart practice for large farms!.
