Premier Select Sires Partnership Brings Rumen Genomics to Eastern U.S.
Premier Select Sires Inc. and Native Microbials Inc. have announced a partnership that will give dairy producers in the eastern United States access to Galaxis Frontier, Native Microbials’ flagship rumen genomics solution. The agreement allows Premier Select Sires to sell and distribute the product, broadening Native Microbials’ reach while adding a new dimension to Premier’s herd improvement offering.
Beginning in September 2025, producers will be able to order Galaxis Frontier through Premier’s sales representatives. The product, already in use across regions including California’s Central Valley, the Pacific Northwest, the Rocky Mountains, and the Midwest, is designed to optimize rumen function and improve herd performance.
Galaxis Frontier: Rumen-Focused Genomics Technology
Galaxis Frontier is described as the only anaerobic rumen microbial consortia containing four native-rumen species that perform critical biochemical functions in dairy cows. Farmers using the product have reported higher colostrum yields, improved feed efficiency, and reduced metabolic diseases. Research has also shown positive effects on immune function, energy metabolism, and mammary development.
“Producers may be surprised to know that there are a lot more opportunities to influence the performance of a bovine through the genetics of the rumen microbes than the actual bovine genome,” said Kirk Sattazahn, Vice President of Marketing and Development for Premier Select Sires. “The rumen is the power unit of the cow, and it makes sense to influence health and production right at the source. We are very excited to bring this technology with proven research and development to our customers.”
Native Microbials Brings Genomic Precision to the Rumen
Native Microbials co-founder and CEO Michael Seely highlighted the scientific platform behind Galaxis Frontier. “At Native Microbials, microbial genomics is the foundation of everything we do. Our data consistently shows that reintroducing higher concentrations of the highest performing rumen genomes back into the rumen habitat reshapes the microbial community, enabling superior outcomes for the cow.”
He added: “We’re proud to partner with Premier Select Sires, whose expertise in bovine genetics has transformed dairy herds for many years. Together, we’re expanding the application of genetics from the bovine genome to the rumen microbiome. This new layer of genomic precision will help dairy farmers improve profitability while supporting healthier and more sustainable herds.”
Premier Select Sires and Native Microbials Expand Dairy Genomics Options
Premier Select Sires, a farmer-owned cooperative with nearly 90 years of experience in bovine genetics, sees the addition of rumen genomics as a natural extension of its mission to deliver herd improvement solutions.
“Just like bovine genomics changed the dairy industry by enabling more precise and rapid genetic progress, the utilization of rumen genomics will be a catalyst to optimize the efficiency and production of our dairy cattle,” said Jeff Hostetter, Product Manager for Premier Select Sires.
With this partnership, both companies aim to deliver a technology that combines microbial science and herd genetics, providing dairy producers with new tools to improve herd health, productivity, and profitability.
