Quality Control_SBS Extender LabThe SBS network of affiliates is the acknowledged leader in the field of cryopreservation of equine semen. Each year we freeze thousands of ejaculates equating to tens of thousands of doses. In fact, this year the SBS Network will surpass the 50,000 ejaculate milestone since the company’s founding in 1987. When SBS was founded the company leadership made a commitment to quality of the finished product above all else. We wanted to put technology to use to help grow the equine frozen semen AI industry in the most responsible manner possible. It was clear early on that one of the major factors limiting the application of frozen semen in the horse industry was inconsistent quality of the product being put on the market. Breeders and veterinarians experienced frustration with attempts to use expensive semen that in many cases was of very poor quality. We knew that in order for breeders to realize the full potential of frozen semen technology they would have to be convinced that by applying strict standards for quality, frozen semen could be produced to achieve results similar to cooled semen. We also knew that these results would have to be produced in an efficient and economical way. Quality became the cornerstone upon which we would build our business.

Heat Stress and Equine Reproduction

September 09, 2014

Posted by Paul Loomis in Stallion Management

Istock_sweaty harness horse cropped During those dog days of late summer and the end of the breeding season, most of us who work in equine reproduction are ready for a break. You are left with those difficult mares that didn’t settle earlier in the season and stallions that may be growing tired of breeding. Mares may not cycle as predictably or conceive as readily and stallions may be tougher to collect or exhibit a decrease in semen quality. One of the factors that can contribute to these problems is heat stress. As ambient temperatures rise, stallions and mares may experience disruptions to normal reproductive function as a result. This article will briefly describe some of the effects of heat stress on mare and stallion reproductive function.

Why Freeze Stallion Semen?

Why Freeze_Tank Room SBSW All too often we hear tragic stories about the sudden death of a stallion whether it be due to an illness or an accident no one anticipated. He may have been a mature stallion who was already proving himself as a sire or a young stallion but now the world will never know his genetic capabilities. These conversations usually end with the stallion owner saying, “I wish I had frozen semen from him.” Or a mare owner saying, “I wish they had frozen semen on him because he would have been a wonderful cross with my mare.” It doesn’t have to be this way.

Sperm Accumulation in the Stallion

Sperm Accumulators_Sperm Photo cropped Have you ever wondered what happens to all those sperm the stallion produces every day (5 billion or more)? If he is not bred or collected then where do the sperm go? We know that sperm are produced in the testicle and move from the testicle into the efferent ducts and then into the head of the epididymis. It takes about 7-10 days for sperm to travel from the head of the epididymis to the cauda epididymis (tail; figure middle right). This time frame is not altered by how often the stallion ejaculates. The old wives tale that you can get immature sperm if the stallion is bred too often is just not true.
