Representatives

If you’re a breeder interested in joining Bos Sires, contact the representative for your country. They can provide details about our cooperative, explain the membership process, and help determine if your breeding program aligns with our mission.

Please note that representatives may not always handle distribution, as genetics access is managed separately in some regions. Reach out today to learn more about joining this groundbreaking initiative.
