NZ Dairy Farm Nears 1 Million KgMS Milestone with Wearables

A Canterbury dairy operation is close to hitting a production record by using neck collars to track 1,850 cows.
Key points
- The farm manages 1,850 cows using two separate milking sheds.
- Wearable neck collars help track health and mating readiness.
- The operation produced 986,000 kg of milk solids last season.
In Canterbury, New Zealand, dairy farmers Sian Meijer and Rick Wobben use wearable tech to manage 1,850 cows. Their farm near Rangiora operates as a single unit despite using two separate sheds.
The operation is close to producing one million kilograms of milk solids. This milestone has been a long-term goal for the team since they began working on the property.
Neck Collars Add Precision To Herd Management
The farm introduced Afimilk AfiCollars two seasons ago. These devices are worn around the cow’s neck to track activity and health.
The data helps the team make better daily decisions. It improves efficiency and helps identify cows ready for mating earlier.
As reported by Rural News Group, the tools are now a core part of their routine. They support the complex logistics of running such a large-scale business.
Two Sheds Handle Different Cow Groups
The main shed milks up to 1,200 cows at peak times. It uses an 80-bail rotary platform, which is a circular milking system.
The smaller shed handles younger and lighter cows. It holds about 600 to 650 animals, including heifers that calve in spring.
The herd split-calves, with most cows calving in spring and some in autumn. This allows for continuous milk production throughout the year.
Genetics Focus On Function And Efficiency
The farm prioritizes functional Holstein Friesian cows. They want animals that are not too large but still produce high milk volumes.
