National Association of Animal Breeders (NAAB)
Sexing Technologies is a member of the National Association of Animal Breeders (NAAB) and Certified Semen Services. We follow all parameters recommended by these two organizations in our semen collection, processing, and housing of the donors. Our goal is to maximize semen production by providing the bulls with maximum of comfort and by taking all of the necessary steps to minimize stress at the time of collection.
Bulls are collected using steers for live mounts in climate controlled arenas. The semen is identified with bar coded stickers at the time of collection and is followed with the same ID through all of the processing steps.
Certified Semen Services
To produce sexed semen, the sample needs to have high motility and very good morphology to pass the rigorous quality control (QC) standards established for the process. These QC standards are evaluated pre- and post-sexing to ensure that our customers are receiving an optimum product. These same parameters are used for the conventional semen collection. This is what ST has developed and staked its reputation on for high quality semen around the world.
This is what makes ST-collected semen famous for its high quality around the world.
