Artificial Insemination

Artificial insemination, or deposition of semen in the female without contact between the male and female, is a common practice in most mammalian and avian species. This was the first application of genetic technology to livestock.[3] After semen is collected from the male, it is usually processed and stored to maintain maximal fertility until it is deposited in the female. Short-term storage of semen usually occurs at ambient or cool temperature. The optimal diluent for semen and storage temperature vary with species. The limitations of maintaining fertile semen with liquid storage of semen were overcome with the discovery of methods to store semen indefinitely by cyropreservation. The techniques for cryopreservation (diluents, temperature, additives, and freezing and thawing rates) vary with species. Chicken and turkey semen can be maintained for insemination as liquid, in a suitable medium, or frozen using a cryoprotectant. Pregnancy rates obtained by insemination of females with cryopreserved semen vary with species. When beef cattle are inseminated with semen after cryopreservation, fertility is similar to that which occurs with natural mating. However, pregnancy rate is reduced 10 to 15% when sows are inseminated with frozen-thawed semen compared with natural mating. Additional research will result in new techniques to improve pregnancy rates after insemination with frozen-thawed semen.
