“I was nervous about trusting the collars, believing that you can’t teach an old dog new tricks, but then I thought I have to trust this technology,”

Michael Smith


Farm owners Michael and De-Anne Smith already had a Protrack system operating in their dairy shed, but last November (2020) they put Allflex monitoring collars on their 350 cows.

The Allflex collars offered full integration with their Protrack auto-drafting system and linked directly with the Protrack system on their desktop computer at the dairy office and home. The Sensehub app helps them keep in constant touch with the herd.
