In-line Sensor


Daily cow information for better informed decisions and greater profitability

Aware some cows are struggling but the signs aren’t being easily picked up? Could your herd to be more profitable if you could track their individual production?

Do you worry if you’re going to grade or whether your plant is being cleaned or maintained properly?

Stepping up to an In-line Sensor solution will provide you with significant benefits from dairy automation and a substantial return on your investment.


"We use MilkHub's mastitis detection to help us stay on top of our BMSCC. MilkHub alerts us to cows to check, we mark them and strip them or keep an eye on them for a few milkings. The worse thing for us would be to have a mastitis problem and have to RMBT or strip the entire herd. We don't have to do that."
- Henry Cowley, Farm Owner, Waikato

Milking Herd ManagementIn-shed PracticeMiHub Mastitis Reports



The measurements you want
Cow mastitis, yield, plant cleaning and milking measurements in one compact, easy to install, cost effective sensor
Install and forget the sensor – it cleans in place, has no moving parts, no reagent, and no effect on vacuum
Save time, money and stress in managing mastitis – just check cows the sensor ranks every milking for likely mastitis – no need to strip the whole herd
Know individual cow production from yield measurements for every cow milked and keep an eye on your low producers
Have confidence your cleaning process is up to standard and avoid hygiene grades
Be sure your plant is milking properly, find bails with faulty rubberware or air leaks
MiHub Premium gives you more
Quickly find sick cows from change in mastitis or yield measurements
Drill down to get details of cow mastitis symptoms and yield, looking back in time to see how cows are performing
Compare cows against herd or group trends to find poor performers
Use built-in ranked lists to find cows most in need of action
Easily sort, select and make groups of cows based on age, health, feed mob, breeding status or any criteria you wish
Quickly look across the whole herd with easy to read graphs to show performance spread and exceptions
Look at herd trends for seasonal tracking and performance so you can take timely action
Quickly set up and control the information and alerts you want to display in-shed for immediate action at cups on or cups off
Information in-shed when and where you need it
See cow performance at a glance on the large easy to read MilkHub Display Screen with cow in-bail information, colour coded alerts, groups and more
Take action when it counts from display and sounder alerts at cups on or cups off – before health problems set in
Enter your treatments or events using the Keypad at cups on or cups off to maintain cow records and automatically generate and display cow withholding alerts
Quickly enter breeding heats, AB’s and PD’s using the Keypad to record against the cow and display as breeding status.
Fix incorrect and missing VIDs on the spot with the Keypad
