Calving

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.

Extended lactation is emerging as a potential option for dairy farmers looking to reduce labour pressure, improve flexibility and significantly cut the number of non-replacement calves being born each year. Anne Lee speaks with DairyNZ senior scientist Dr Paul Edwards about the research behind the system and the results emerging from farmlet trials at Scott Farm and a new study in Northland.

In this episode, Sarah Perriam-Lampp talks with William Morrison from Morrison Farming about supplying beef genetics to the dairy industry. He explains how decades of performance recording have produced easy-calving, fast-growing cattle, why reliability matters most for dairy farmers, and what to expect from the upcoming Ardo Hereford sale on 23 September.

In this episode, we discuss pregnancy scanning results across the country, with some farmers reporting low not-in-calf rates. We also explore the importance of planning for next season’s mating, selecting the right bull team, and how advancements in breeding technology, including sexed semen, are helping farmers improve herd efficiency and productivity.

A busy calving season is underway across the country, and for farmers calf nutrition will be top of mind. In this episode we look at the different ways to develop your calf’s rumen, to raise healthy and feed-efficient cows. Hear from Jacqueline McGowan from DairyNZ about developing the rumen; Grant Jackson from SealesWinslow about raising feed-efficient cows; and Penelope Drysdale, a Manawatū farmer, about how integrating an organics system has benefitted her herd’s health.
