hen it comes to selecting a breeding stallion for that special mare, breeders have come a

long way from having to choose a stallion in the mare’s proximity for live cover. With artificial insemination (AI), fresh chilled semen has become one of the most popular ways of obtaining semen from a distant stallion. However, using frozen semen gives mare owners access to top stallions from around the globe, not to mention from stallions that are deceased or gelded. It can sound very exciting to mare owners as the possibilities are almost endless...

BUT the technical aspects can be overwhelming and confusing, and some of the myths and misconceptions can be intimidating and discouraging. We’ve talked with experts in the field of frozen semen breeding and brokering to answer some of the most common questions and concerns about frozen semen. Judy Yancey of Yancey Farms began breeding

Warmbloods in 1975, initially with fresh chilled semen. She started using frozen semen in 1984 when she began standing the Trakehner stallion Donauwind *E*. She is now one of the best known frozen semen brokers in the United States, with a current roster of 34 stallions, including such famous names as Sandro Hit, Don Schufro, Quaterback and Balou du Rouet. Karen Reid began breeding with fresh chilled semen in the mid 1980’s. She became involved with frozen semen in the mid 1990’s, when she began brokering semen for the Holsteiner stallion Cheenook. She has now expanded her frozen semen brokering services to include 18 stallions owned by the Holsteiner Verband, as well as standing four prominent Holsteiner stallions at her own Fox Fire Farm in Washington. She currently sits on the board of directors of the American Holsteiner Horse Association. Siegi Belz-Fry is a very successful breeder of Dutch

Warmbloods, earning the prestigious KWPN-NA Breeder of the Year award in 2007. She began breeding Warmbloods in 1985. She became involved with frozen semen in 1992 when she began standing the Trakehner stallion Veneziano. Veneziano was only ever available via frozen semen, which was a bold move in 1992.

FROZEN SEMEN 101

Semen is collected for freezing in the same way as it is collected for shipping fresh chilled. After collection it is centrifuged into ‘sperm pellets,’ mixed with a freezing extender, and loaded into ‘straws’ which generally range in size from .5 ml (roughly the size of a coffee stirring straw) to 5 ml (roughly the size of a drinking straw.) The straws are then frozen in liquid nitrogen. The frozen semen straws are stored in a liquid nitrogen

storage tank. It is believed that frozen semen may be stored indefinitely in the storage tank, with successful results thus far achieved with frozen semen stored for decades. Frozen semen is shipped in a container known as a ‘dry shipper.’ Fresh chilled semen is hardier than frozen, which
