The MurrayGreyTank Semen Catalog
A real, printed catalog of Murray Grey semen and genetics — mailed to breeders so it lands on the kitchen table right when mating decisions are being made. Two editions a year, timed to breeding season on each side of the equator. Every member gets a digital copy; submitters can receive a printed copy in the mail.
🌎 Northern Hemisphere Edition
North American and European herds mostly calve in late winter and spring, which puts AI season in May–July. This edition mails in early March, while sire lists are still open.
