What really makes a cow go lame, and why did it take so long to change our minds? We sit down with Professor Jon Huxley—raised on a Welsh dairy, now leading Massey University’s vet school in New Zealand—for a candid tour through research that reshaped mastitis control, lameness prevention, and fresh cow care.

Jon shares the story behind teat sealants becoming a cornerstone of selective dry cow therapy, showing how solid trials helped cut antibiotic use without compromising udder health. We then tackle the big pivot in lameness thinking: moving beyond the old acidosis-laminitis narrative to the digital cushion, body condition, and the brutal role concrete plays in claw horn lesions. The result is a practical blueprint—protect condition around calving, improve surfaces and cow flow, and trim with function in mind.

Treatment gets equal airtime. Randomised trials demonstrate why NSAIDs matter for lame cows, reducing inflammation and pain to speed recovery. Extend that approach to fresh heifers and the benefits often reach into second lactation. From there, we zoom out: are mastitis, metritis, ketosis, and lameness different faces of the same early lactation inflammatory stress? If the transition cow is the most fragile athlete on the farm, then feed space, comfort, calm routines, and energy balance are one system, not a checklist.

We also compare UK housed systems with New Zealand’s pasture-first dairying: longer walks on laneways, fewer hours on concrete, and lower lameness, but rising buffer feeding, new shelters, and tough conversations on nutrient leaching. Along the way, John explains how Massey’s hands-on facilities and the Kiwi “give it a go” mindset produce work-ready vets who can turn evidence into action.

Listen for clear, usable insights on mastitis prevention, lameness treatment, digital cushion management, underfoot design, and the transition period. If you want fewer sore feet, fewer sick fresh cows, and more sustainable milk, this conversation pulls the science onto the yard.
