What does the UK's third-highest PLI Holstein herd discover when they test every calf born on their farm? Stuart and Helen Rogers of Longmoor Farm reveal how genomic testing transformed not just their breeding decisions, but their entire approach to dairy farming.

When the Rogers family moved their pedigree Holstein herd from Oxfordshire to Dorset in 2011, they wanted to push their genetics forward. What started with tentative use of genomic bulls evolved into a comprehensive strategy where every calf born gets genomically tested at birth. The results challenged their perceptions of which cow families were truly valuable. "The cows that you forget about in a herd are actually your really good earners," Helen explains, "the ones that aren't lame, don't get mastitis, and just do the job without you even worrying about them."

Their seven-year strategy of using sex semen on high-ranking heifers and first lactation animals while directing beef semen to the rest has yielded remarkable results. Their fertility performance outshines most farms with pregnancy rates consistently between 34-38%. Cell counts hover around 70,000, and their antibiotic usage has plummeted to just 5.6mg per PCU—about a quarter of the UK average. Perhaps most impressively, they've eliminated fat supplements from their diet while maintaining 11,500 litres at 4.5% butterfat through pure genetic selection.

For farmers considering genomic testing, the Rogers' advice is straightforward: commit fully rather than dabbling. At approximately £22 per test, the investment quickly pays dividends through improved decision-making. "It's so little money in a lifetime for a cow," Stuart notes, especially when you consider the compounding benefits across health, fertility, and production. Whether you're managing a pedigree or commercial herd, their experience demonstrates how embracing genomics can create a more balanced, resilient and profitable dairy business.
