Calves

Karen Fraser has spent years helping dairy farmers improve calf rearing through practical, science-based advice. Anne Lee speaks with the Farmlands Technical Specialist and Calf Experts co-founder about the foundations of successful calf rearing, from colostrum management and the five Qs of colostrum to early-life nutrition and milk feeding.

Dr Ajmal Khan has spent more than a decade researching calf rearing, investigating how early-life nutrition and management influence the health, productivity and lifetime performance of dairy animals. Anne Lee speaks with the Bioeconomy Science Institute scientist about his latest research into colostrum management, milk feeding and pre-weaning growth, and why getting those first days and weeks right can have lasting benefits for calf health, milk production, longevity and farm profitability.

In this special episode, Sarah Perriam-Lampp sits down with Andrew MacPherson and Cara Sheridan to unpack the arrival of Bovillus Cryptium, a new vaccine for calves targeting cryptosporidiosis, and what it means for farmers managing calf health in New Zealand. The discussion sets the scene for why this vaccine is a game changer, how it can improve calf welfare and long-term performance, and why proactive planning with your vet is key to getting the most from it. With spring 2026 calving approaching, now is the time to understand how to integrate this new tool into your farm systems.

The rewards for good preparation leading into calf rearing won’t just be felt this spring, they’ll go on for years as well-grown heifers become productive, long-time members of the herd.

In the first episode of The Dairy Exporter Podcast, Editor Sheryl Haitana & Deputy Editor Anne Lee delve into the study at Lincoln University’s Ashley Dene Research and Development Station that looks at a suckling calf rearing system, where cows and calves are kept together until weaning.
