      Semen Freezing Forceps Semen Freezing Forceps are used to handle semen straws that are being processed and stored. These stainless steel Rochester-Pean style forceps are 12" in length with serrations running the length of the tip to provide a better grip. In equine artificial insemination (AI), cryopreserved semen is used far less frequently than fresh or cooled-stored semen [1,2].This is at least in part due to differences in the fertilizing capacity of frozen–thawed semen among stallions [3,4,5,6].Furthermore, cryopreservation of semen is associated with substantial ://

Overview of frozen equine semen by Rupert P. Amann Download PDF EPUB FB2

Over the last 30 years the use of frozen semen in the equine industry has increased significantly and has become a relatively common method for producing horses of numerous breeds. The increased use of frozen semen can be attributed to improvements in techniques for semen cryopreservation, availability of reliable ovulation induction drugs /collection-management-and-distribution-of-frozen-equine-semen.

Equine semen can be frozen in ml straws like those used for cattle. In that case, between one and eight of them are required per insemination (Figure 11). and edited the book Equine   Thus, frozen semen becomes the "backup plan" for breeding mares. You can find additional information to consider when deciding if frozen semen is a fit in your breeding program by reading these articles on the SBS Website: ‘Why Freeze Stallion Semen?’, ‘The Pros and Cons of Equine Frozen Semen’ and ‘The Hidden Value of Frozen Semen’ Frozen semen is also closing the gap between frozen and chilled semen, achieving pregnancy rates of 30 to 70 percent per cycle with ongoing research to further improve frozen semen standard.

Overall, cryopreservation of equine spermatozoa allows the production of superior progeny marketed internationally and the preservation of our favoured Paul founded Select Breeders Services in with the belief that equine breeders needed a reliable source for the burgeoning artificial insemination technology.

Beginning with a single laboratory and the willingness to travel throughout the United States to work with forward thinking breeders of Warmblood Sporthorses, and Standardbred racehorses, SBS quickly developed a reputation for OVERVIEW.

SBS is the largest provider of frozen semen services in the world, with unrivalled expertise accumulated over its twenty five years leading the frozen semen industry. SBS has an affiliate network consisting of 25 equine reproduction laboratories, 15 in North America, 7 in Europe, 2 in Australia, and 1 in Central ://   Charges for shipping must be born by the breeder, same as the government vet’s certificates per stallion and consignment for shipping of semen outside Germany (charges for shipping + approx.

45,- euros). For shipping of frozen semen, the customer provides the container and pays a 2 days ago  Frozen semen is an excellent way to provide insurance against future infertility, over booking, or death of the stallion.

Once frozen, the semen will keep indefinitely in liquid nitrogen. It is critical that semen be of excellent quality prior to freezing and is processed properly by someone experienced in stallion semen Last year, LLC was asked to assist in fertility evaluation of semen frozen from the great Olympic show jumper "Galoubet A".

Galoubet himself had died inand the semen had been frozen in the mid to late ' A brief overview of the freezing process reveals that sperm are separated from the seminal plasma; a freezing extender is added at a certain concentration; the re-extended semen is packed into "straws" at a known sperm concentration; the straws are frozen using liquid nitrogen, and are then submerged and kept stored in the liquid nitrogen until   The included Freezing Straw Filler replaces mouth pipetting while filling the semen straws.

The book "Techniques in Equine Reproduction" is a comprehensive guide to equine reproduction including a chapter devoted to semen freezing and storage. Working with Liquid Nitrogen while freezing stallion semen requires specialized safety :// Semen sold on a per dose basis for hundreds or even thousands of dollars imparts a significant pressure on the mare owner and veterinarian to use only one dose of frozen semen per cycle, since the cost of the extra ultrasound examinations incurred when breeding with one dose is generally less than the cost of purchasing an additional dose of Find farms and stallions that are offering shipped frozen horse semen for artificial insemination.

If you stand a stallion, it's free to advertise with :// The main advantages of frozen semen are long‐term preservation of genetic material, insurance against unanticipated loss of a stallion, access to frozen semen if fresh or cooled semen is not available, and ability to ship semen worldwide.

Unfortunately, the spermatozoa from some stallions do not freeze ://   In the case of frozen-thawed semen, optimal pregnancy results are obtained when breeding within 6 hours of ovulation.

If the semen quality is excellent, one can stretch it up to 12 hours, but I do not recommend it. Insemination with frozen-thawed equine semen beyond 12 hours before or after ovulation will yield extremely poor pregnancy :// With frozen semen you can service a larger book of mares with less stress on your stallion and less headaches for you.

Because it is more efficient frozen semen can be less costly than cooled semen. With frozen semen, there are no wasted doses and you do not need to maintain the staff and facilities required to accommodate a cooled semen Semen may be diluted up to fold, depending on the initial concentration, the processing and storage method, and whether the semen will be used fresh, chilled, or frozen-thawed.

Most semen extenders have a buffered egg yolk base and cryoprotectants such as glycerol. These extenders can be used for semen destined to be used fresh or :// The success of frozen semen programmes depend on healthy fertile mares, good quality semen and a high degree of attention to detail and technical precision from the equine vet.

The great advantage of frozen semen is it is ready for use at any time, unlike chilled semen where the timing of insemination is often dictated by freight ://   The decreased pregnancy rate with frozen-thawed equine semen may be attributed to a decline in the post-thaw motility and/or a reduction in the longevity of sperm after thawing.

Stallion semen is generally centrifuged prior to freezing or cryopreservation so   The Large Animal Theriogenology Service provides the following services: Equine Bovine Ovine Caprine CamelidBreeding Management X X X XX Shipping of cooled & frozen equine semen for breedingX Breeding soundness evaluations X X X X X High-risk pregnancy monitoring X X X X X Embryo collection and transfer X X Bull semen collection and freezing X Stallion collection training X.
