OUR GOALS
-
A low cost, affordable, quality product that adds value to your bottom line, and adds enjoyment to your business. All our semen is processed at Hawkeye Breeders in lowa, and every unit is packed with an industry leading 30 million cells, with stringent post freeze quality standards
-
A small, complete lineup of elite sires that fill your every need. Commercial production, Show ring type, high classification, A2/A2, RC, Red, and aAa, polled as well as outcross pedigrees. We also now have a well-rounded lineup of Jerseys, all being A2/A2, BB, and JNSF!
-
Provide an alternative to the other studs already utilizing both older bloodlines, and the latest genomic technology. We want to present a middle track, free of genomic restraints, and focused on the cows and real world performance. We believe in the cows that made the numbers more than the numbers we hope might someday make cows!
WE WORK HARD TO MAKE OUTCROSS OPTIONS AVAILABLE FOR YOU!

OUR STORY
Ben, Ethan, and Rusty all grew up on their respective family dairies and have had their own dairy herds. With Ethan and Rusty’s extensive careers in reproduction in the dairy industry, and Ben’s lifelong passion for genetics and their mutual faith in the Lord, when they met they soon became friends.
As the three talked, they found common ground: concerns about the state of the industry and the A.I. climate, real-world experience with these genetics on their own farms, and a marketplace short on diversified offerings. Together, they decided to do something about it; to add value back to the farms, the dairymen, and the cow families that generations of breeders have worked to develop.
It has been a fast four years since the birth of NoBull. We have been overwhelmed by the reception of our bulls in the marketplace, and hope NoBull can serve as a preserver of quality cattle, and passion for breeding world-wide.
Rusty lives in Chester County, PA, with his wife Heather and their three daughters and one son, and now works full time in the reproduction industry. Ethan lives with his wife Gabrielle in York County, PA with their three (and counting??) sons, and also works full time in the reproduction industry. Ben lives in Berks County, PA with his wife Cassandra and three daughters and one son, where he milks a herd of 75 robotically on his family farms.
We feel being in the field and in the barns on a daily basis helps keep us in touch with the industry we have spent our lives being so passionate about. We look forward to getting to know you all more each year, with every visit and phone call. It is our hope that what we are doing adds value to not only the breeders of our bulls, but your herds as well, and value to your milk check for decades to come.
