Congratulations to Heather DeGarmo of Florida who has won a $100 Amazon.com gift certificate for her photo of Karizma by the stallion Kjento out of the mare Romantica II.

The most commonly used measure of semen quality is sperm motility, specifically “progressive motility”. But what exactly does that mean and how is it determined? The minimum post-thaw “progressive motility” generally recommended for commercial distribution of frozen semen is 30% to 35%. This article will address some of the factors that can affect the assessment of sperm motility as well as the various problems associated with techniques used for determining “progressive motility”.

At SBS, we are often presented with young stallions for semen collection and evaluation. There are a variety of reasons that stallion owners want to have semen collected from their young stallions including; 1) evaluation of sperm production and quality to assess suitability as a breeding stallion, 2) training to collect on a phantom with an artificial vagina in preparation for a breeding career and 3) to collect and preserve semen from a young stallion prior to castration or starting a performance career.

From breeding and horse management to laboratory work, Select Breeders Services (SBS) and its affiliate labs in the United States offer various internship opportunities for college undergraduates looking to further their knowledge and skill within the equine industry. SBS is the largest and most professionally managed provider of frozen semen services in the world. In addition, many SBS locations offer a full range of equine reproduction services, and most of the affiliate labs are state of the art veterinary hospitals as well. SBS labs provide excellent teaching and training opportunities at some of the best equine reproduction facilities in the country. There is plenty of exposure to hands on experience and on the job training.
