Outside Michigan, Indiana, and Wisconsin?

CentralStar’s Select Sires-exclusive distribution area is limited to Michigan, Indiana, and Wisconsin. Producers outside this area can become member-owners but must continue to purchase genetics, A.I.-technician service, and CowManager® through their local Select Sires cooperative.

Other products and services, including DHI and diagnostics, are available nationwide and count toward your annual purchase requirement.
