Frozen semen is available on hundreds of retired purebred-pedigreed and crossbred sires previously on stud at SGI, plus all boars currently housed in our stud. Our frozen semen technology has allowed us to preserve the genetics of hundreds of proven, superior sires that date back to 1981. Our vast library of high-performing breeding animals provides customers an efficient method of genetic transfer with reduced risk of disease transmission. We have found that our frozen semen inventory has provided irreplaceable genetic tools for firms looking to revisit the value-added traits found in production hogs of the past, and capitalize on today's technologies to differentiate themselves as they work to diversify current genetic lines.
