About Us

Nebraska Bull Service (NBS), is the Premier Custom Collection Facility and is dedicated to the people it serves and the quality semen it supplies. In 2001, the facility was relocated to its current location in McCook, NE, right in the heart of beef country by Brian & Donnetta Schafer. Accelerated Genetics acquired NBS in 2013. And in 2017, Vogler Semen Centre, Inc of Ashland, NE purchased NBS.
