North American Genetics: The Secret to Ireland’s Champion Holsteins

The success of Hallow Holsteins, a 100-cow pedigree herd in Wexford, Ireland, highlights the global impact of North American dairy genetics. By importing around six embryos annually and utilizing AI bulls from the U.S. and Canada, the farm prioritizes cow type and conformation traits necessary for high milk production.

Owner Philip Jones credits their accolades in Irish dairy competitions to these superior genetics and a focus on strong cow families, particularly the Twizzle family, originally imported from the U.S. Hallow Holsteins employs high-tech herd management strategies, including 100% AI with 95% sexed semen to ensure a consistent supply of replacement heifers, and a split calving system to maintain year-round production of an average 10,500kg of milk with high butterfat and protein components.

Despite challenges such as derogation limits in dairy farming, the Jones family practices advanced marketing techniques, using agricultural shows to reach international buyers drawn by the herd's recognized genetic quality. Their strategic approach offers a promising model for farmers aiming to balance high production with environmental regulations.
