Shuttle Stallions - Frozen Semen to the Rescue

June 28, 2017

Posted by SBS in Stallion Management

Considerations for Exporting Frozen Semen - Lufthansa #2 Shuttle or Dual-Hemisphere Stallions are terms used to describe breeding stallions which travel between the Northern and Southern Hemispheres for their respective breeding season. Several questions arise when discussing shuttle stallions and may include: Why do stallion owners incur the costs and risks of sending their stallions thousands of miles away? Does the lack of sexual rest affect their fertility? Is there a way to service mares in a different hemisphere without sending the stallion so many miles away?

Seminal Plasma: The Good, The Bad and The Ugly

Seminal Plasma_Gel Filter Removal To understand why seminal plasma is beneficial in some situations and potentially harmful in others we must first review what it is, where it comes from and what we think are its roles in reproduction. The term seminal plasma refers to the fluid portion of ejaculated semen in which the spermatozoa are suspended. This fluid consists of secretions from the accessory sex glands in the stallion’s reproductive tract. These include the ampullae, the vesicular glands (seminal vesicles), the prostate gland and the bulbourethral glands (figure 1).

Analysis of Frozen-Thawed Equine Semen

April 11, 2017

GVEH Scope Once equine semen is frozen it is recommended that a post-thaw analysis be performed in order to ascertain the semen quality. There is variability in how well sperm from different stallions respond to the cellular stress of freezing and thawing. It is important to determine how well the sperm from a particular stallion withstood the stress of cryopreservation in order to make informed decisions regarding the management of their frozen semen inventory and breedings. Also, when we freeze a stallion for the first time we do a test freeze comparing several different protocols. We then use the post-thaw motility to select the freezing protocol for subsequent collections which gives the best post-thaw result. There are industry recommended minimums for commercial distribution of equine frozen semen and therefore it is pertinent to know if your stallion’s frozen semen would qualify. Consequently, the analysis of frozen-thawed semen is a valuable tool for the semen freezing lab, but also for the veterinarian receiving the semen. Your vet may base the breeding management of your mare upon the post-thaw quality of the semen. Also, many vets take a look at the motility of the frozen semen at the time of insemination, for future reference if there are concerns should the mare not check in foal.
