Breeding deceased stallions offered via injection technique

A reproductive technique called intracytoplasmic sperm injection (ICSI), in which a sperm is injected directly into an egg led Foals from many mares that were no longer able to. However, it may be just as important renewal valuable genetics of stallions, the Dead for decades.

The ability to freeze sperm in stallions has been for many decades. It is not an exact science. In contrast to the bovine species, the very consistent quality when has frozen, the success of freezing Stallion semen very dependent on the individual stallion. For reasons that still are not fully understood, many stallions do not freeze well, even if they have good fertility with cooled or raw seed.

Complications of the image was the fact that many horses were only for semen freezing, when they were in their declining years, or suffering a debilitating condition collected. Therefore, the sperm cells collected and frozen the best quality. This exacerbated the problems of pregnancies with frozen semen. Regardless, have selected in the last decades, many owners, their semen stallions . Freeze While it is solidified, they were before the game. If the stallion Freezing was not good, the sperm that they use the semen enable technology of the future would still often in the hope kept.

Scientists are still working on developing better freezing protocols Extender components and antifreeze production results with frozen Stallion semen increase. In the meantime, now offers the ICSI with frozen Sperm, even if poor quality, a very realistic chance to Multiple pregnancies from a single straw to produce seeds. Since only one sperm is required for sperm injection, it is not necessary to use more straws to try a single Achieve pregnancy. In addition, the sperm only viable DNA. The post-thaw motility is not a factor. By the injection of the cells mechanically sperm into the egg, the Need a highly rod-shaped sperm bypassed.

Recognized the potential for access to these rare genetics and Opportunity for new growers of the earlier dynasties and contemporary Bloodlines create innovations has Equine Reproduction of Wellington, Colorado, a "Legends" program for stallions standing sperm of deceased created through the use of ICSI. Other stallions that some breeds are in the coming weeks and months to be announced. ERI treated seed for Stallion Mares each user via ICSI, sexed semen, embryo transfer or conventional artificial insemination want to breed.
