OUR FOCUS:
• World class production, enabled by world class type.
• High components, as that is truly what our milk checks are based off of... we have to pay trucking on water! Balanced type. High pins or frail front ends are a recipe for disaster, and sooner or later, cost to the dairymen.
• An emphasis on breeders, and long lived, deep pedigreed cow families. The more proven, real world quality in that pedigree, the more likely you are to get some of it in your herd, the whole reason we source genetics to begin with.
• Balanced crosses, and complimenting pedigrees. There is an art to breeding, and articulation of that cross in the end usually yields far more results than guess ink on a page. Proven, golden crosses also capitalized on, free of genomic devaluing.
OUR GOALS: POWER TO THE BREEDER
1. A breeders stud by breeders, for the breeders
2. 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
3. Every sire retained at stud until a full milking daughter proof. Use them, keep using them, and if you like the daughters, we will have more!!!
4. 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!
5. 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!
OUR STORY

NoBull Sires LLC partners (Left to Right) Ben Masemore, Ethan Wentworth, and Rusty Herr at their first World Dairy Expo in 2022. The three friends 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.
When the three began to share ideas and thoughts about the state of the industry, the A.I. climate, and the on-farm, real world experience with these genetics and the lack of diversified offerings in the marketplace, they decided to join forces and do something about it to add value back to the farms, and dairymen everywhere, and the cows and cow families they have worked so many generations 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.
