Roanoke A.I. Laboratories is one of the oldest and most trusted names in cryopreservation of stallion spermatozoa in the USA. We have experience boarding, collecting, and freezing semen on over 300 stallions. Sperm from our lab produced the first foals sired by frozen semen from many breeds: light horse, draft, and the endangered Grevy's zebra (Equus grevyi). We have internationally published some of our research and continue to be pioneers refining semen cryopreservation and collection techniques in horses and exotic equids.
