Breeding With Chilled And Frozen Semen
نویسنده
چکیده
Artificial Insemination (AI) involves the introduction of sperm into the reproductive tract of the mare without natural mating. AI in the horse was first practiced long ago. Ancient Arabian texts describe how mares were successfully inseminated. In the late 18th Century, an Italian scientist took the idea up again. He performed a series of studies in which he placed stallion semen in the snow and found that he did not necessarily kill the spermatozoa (or "spermatic vermiculi" as he termed them), but merely made them inactive. Upon warming, their motility returned. The use of AI on a regular basis in horse breeding dates back to the beginning of the 20th Century.

Successful artificial insemination in the Asian elephant (Elephas maximus) using chilled and frozen-thawed semen
BACKGROUND Artificial insemination (AI) using frozen-thawed semen is well established and routinely used for breeding in various mammalian species. However, there is no report of the birth of elephant calves following AI with frozen-thawed semen. The objective of the present study was to investigate the fertilizing ability of chilled and frozen-thawed semen in the Asian elephant following artif...

Recent Advances in the Area of Canine Semen Preservation
Although dog was the first species to be used for Artificial Insemination (AI) and become pregnant by Spallanzani in 1776, very little work has been done on preservation of dog semen to exploit the full genetic potential of pedigree males. Frozen semen is now inseminated routinely in cattle, sheep and goats and much research has been carried out with regard to the optimum conditions for its use...

Artificial insemination (AI) is becoming more common in canine reproduction, permitting the use of shipped semen, assistance for geriatric or subfertile males, coverage of dominant females, and advanced reproductive technology such as intrauterine deposition of semen. AI may be performed with fresh, chilled, or frozen semen. All instruments should be clean and free of any chemical contamination...
متن کاملArtificial insemination in canids: a useful tool in breeding and conservation.
Artificial insemination (AI) and semen freezing have become services available to dog owners worldwide, and the demand for services to freeze semen is increasing. In other canids such as the fox, the fur industry utilizes fresh or frozen semen to artificially inseminate vixens to produce pelts. Clearly, AI facilitates the use of a male to sire several females by diluting the ejaculate, increase...
