It’s all about monitoring parameters associated with events of interest, but sensors
May not accurately or precisely monitor these parameters
![Page 35: Sensor technologies in the milking parlour, can they replace or complement human senses to monitor cow health and productivity](https://reader035.vdocument.in/reader035/viewer/2022081520/58ab6ed11a28abb54e8b5273/html5/thumbnails/35.jpg)
It’s all about monitoring parameters associated with events of interest, but sensors
May not accurately monitor these parameters
Monitor a proxy for these parameters
viscosity measurements;Whyte et al., 2004
![Page 36: Sensor technologies in the milking parlour, can they replace or complement human senses to monitor cow health and productivity](https://reader035.vdocument.in/reader035/viewer/2022081520/58ab6ed11a28abb54e8b5273/html5/thumbnails/36.jpg)
It’s all about monitoring parameters associated with events of interest, but sensors
May not accurately monitor these parameters
Monitor a proxy for these parameters
Monitor parameters that are not unique for the event
![Page 37: Sensor technologies in the milking parlour, can they replace or complement human senses to monitor cow health and productivity](https://reader035.vdocument.in/reader035/viewer/2022081520/58ab6ed11a28abb54e8b5273/html5/thumbnails/37.jpg)
It’s all about monitoring parameters associated with events of interest, but sensors
May not accurately monitor these parameters
Monitor a proxy for these parameters
Monitor parameters that are not unique for the event
Monitor one single aspect of a complex event

Always a trade-of between
SensitivityHow many events do you
detect (true positive alerts) and how many do you
miss (false negative alerts)
SpecificityHow many healthy cows do
not receive an alert (true negative alert)
and how many do receive an alert falsely
(false positive alert)

Trade-off dependants
Event being monitored
Dairying system in which sensor is implemented
Economic consequences of decision-making based on inaccurate sensor information
Farmer’s preference (risk attitude)

Example automated mastitis detection
High SN
no additional labour for checking alerts
High SP
nuisance of fetching cows and checking alerts
Willing to accept mildly infected cows remain undetected(Mollenhorst et al., 2012;
Hogeveen and Steeneveld, 2013)
![Page 41: Sensor technologies in the milking parlour, can they replace or complement human senses to monitor cow health and productivity](https://reader035.vdocument.in/reader035/viewer/2022081520/58ab6ed11a28abb54e8b5273/html5/thumbnails/41.jpg)
Example automated oestrus detection with 70% sensitivity
Year-round calving might be OK
But what about seasonal calving?6wks time to get all cows pregnantEconomic losses in case oestrus events are missed

Farmers’ attitude
Being in control Letting-go

Farmers’ attitude
Eager to understand and learn the system Not having the time or skills
![Page 44: Sensor technologies in the milking parlour, can they replace or complement human senses to monitor cow health and productivity](https://reader035.vdocument.in/reader035/viewer/2022081520/58ab6ed11a28abb54e8b5273/html5/thumbnails/44.jpg)

Waiting for ‘improved’ systems(Borchers and Bewley, 2015; Steeneveld and Hogeveen, 2015; Russell and Bewley, 2013)

Use of sensor information is limited
5% of generated mastitis alert lists are visually checked
Reasons not to check alerts included:
No deviation in yield (19%)No flakes on filter (28%) Repeatedly on list (10%)
Too busy (10%)Malfunctioning (4%) No EC increase (5%)

Use of sensor information is limited
5% of generated mastitis alert lists are visually checked
Reasons not to check alerts
Consequence: 75% of detected mastitis is not ‘seen’ (Hogeveen and Steeneveld, 2013)

22% of farm owners indicated that expectations did not match performance reality
24% of farm owners indicatedthat learning support was not as expected (Eastwood et al., 2015)

Sensors are exciting, high-tech and have potential
But we need their information combined with
To complement our management decisions on cow health and productivity
