Preparing Quarter Horses for sale is something many horse owners will be involved in at some point, whether they are directly involved in the preparation process or are a potential buyer. It is a broad topic, as Quarter Horses are commonly sold at all life stages and as part of many different disciplines. This article will focus on how to best prepare, or “fit” horses being sold in an auction setting and the common threads across many of the disciplines Quarter Horses are involved in.Read More
Featured Blog: Cryopreservation of Equine EmbryosBlog RSS Feed
January 30, 2015
Embryo vitrification doesn't sound much like "freezing embryos,” but the end product certainly is a cryopreserved equine embryo, frozen in liquid nitrogen for the preservation of genetics and transfer into a recipient mare at a later time. For the sake of some readers of this blog, an embryo is the result of fertilizing an oocyte (egg) with sperm and allowing the initial stages of development to occur. Embryo vitrification is the process whereby we freeze equine embryos for storage for indefinite periods of time prior to transfer into a recipient mare. We have the technology to cryopreserve equine sperm and equine embryos, but not equine oocytes. Herein lays the answer to the most common question that comes up in conversation regarding this blog topic. Some readers assume that since we can freeze the male generated sperm, we can likewise freeze the female generated oocyte. Unfortunately, due to some very sensitive cytoskeletal components in the oocyte, the technology does not exist to freeze equine oocytes. As we proceed, you will understand the process of embryo vitrification and we will delve into areas of research that are improving the success rates of vitrified embryos in generating live foals.Read More
What do I do with unused semen?
The first thing to determine is who owns the frozen semen? If you purchased the frozen semen by the dose, you own the semen and any unused semen you could save for future use. SBS can store any remaining doses for you. If you received the frozen semen as part of a breeding contract then the stallion owner still owns the frozen semen. Check your breeding contract or call the stallion owner to discuss their policy for unused doses. Usually they will either request all unused semen be destroyed or returned.
Please Note: The viability of frozen semen depends on proper handling and storage, maintaining straws at liquid nitrogen temperatures and minimizing any exposure to temperatures warmer than -100°C. Improper handling during transfer between transport containers and permanent storage, or failure to maintain proper liquid nitrogen levels in storage containers may damage semen. Once semen has left our SBS facility it is impossible for us to verify if the semen was damaged at the receiving location. It is SBS policy to only ship returned doses of semen back to that same mare owner or to the stallion/semen owner for their own use.
