International Protein Sires





Competitive Genomic sire selections at conventional semen prices
Holstein, Red Holstein and Jersey sires

International Protein Sires began as a joint venture with the German AI stud "Top Q Sires"-- seeking out exceptional milk protein production lines.
It is now owned by Ron Sersland, an Iowa farm boy with extensive experience in export of USA genetics to Latin and South America.
Ron continues in the Genomic era to select only from well-developed maternal cow lines, and seeks sires with "well rounded" trait profiles.
