The property has been in the family for almost 100 years and is home to a Royal Oak Holstein Friesian stud, milking 900 cows at peak and 750 over winter. Alastair has been on the farm full time since 1993 and has grown the operation by taking opportunities to purchase neighbouring properties and lease blocks as they came to the market. He says his strategy was purely to be in a position to take any opportunities as they arose – and he has also had a little bit of luck.

“It has been really helpful and accurate so far, the collars have picked up cows that staff have missed, including one silent heat.”

Monitoring Solutions – Branding Explanation

The brand names for our monitoring solution have been subject to changes since recording our videos and farmer stories.

MSD Animal Health, a division of the MSD group of companies under Merck & Co., Inc., Rahway, NJ., U.S.A. and a global provider of animal health pharmaceuticals and technologies, purchased the Allflex New Zealand business in 2019 (including certain SCR-branded animal monitoring technologies). At the time, Allflex animal monitoring solutions were known as Allflex collars and the relevant desktop-based software was HeatTime Pro (both of which you may hear about in this video). The dairy monitoring solutions are now branded SenseHub® Dairy – MSD Animal Health’s desktop-based software is now known as Dataflow II™ and cloud-based monitoring software is known as a SenseHub® Dairy solution. Allflex remains the brand name which represents our identification solutions
