In 2012, Select Breeders Southwest (SBSW) had the honor of welcoming Radical Rodder, the 1998 AQHA World Champion in Senior Western Pleasure, into their stallion barn in Aubrey, Texas. SBSW had previously been freezing semen from him for several years but now they had the opportunity to include him and his owners, Diane Chilton and Dr. Howard Harper, as part of the SBSW family. Many SBSW team members were privileged to be able to be with Radical Rodder for his last trip to Diane’s ranch where he and his stablemate, Tumbleweed, were laid to rest on April 11, 2019. Paul Loomis said,“It was our great honor to have provided a home for this legend on the final leg of his incredible journey. He has been a fixture at SBSW for many years and will surely be missed but not forgotten.”
Knowing and keeping track of the concentration, or the number of sperm per milliliter, of each ejaculate for a stallion is very important for a variety of reasons. The concentration of his semen, along with the volume of his ejaculate, is used to determine the total number of sperm he produces in a given collection. These two numbers (volume and concentration) are used to calculate insemination doses. Also, keeping a record of each number can help stallion managers recognize if there are any changes in the reproductive health of the stallion. Slight variations are likely nothing to be concerned about. However, if the number of sperm in the ejaculate varies drastically, from collection to collection or a steady decrease in his total number of sperm over time, one may begin to ask what is causing the change. This information is valuable so that any concerns can be addressed as soon as they arise.
