This document discusses whether technology pays for itself in dairy farming. It provides an overview of the history of sensor use on dairy farms since the 1970s and their increasing adoption. Success factors for precision technology include system specifications that provide useful information, cost efficiency where benefits outweigh costs, and non-economic factors like risk tolerance. Studies show sensor systems for mastitis and estrus detection can increase productivity and profitability on farms, though their benefits are not always fully realized in practice due to limited use of sensor information and farmer attitudes. In conclusion, sensors have the potential to improve farms economically and enhance dairy cattle welfare but not all systems may be cost-effective.

23. System specification
Description of (prototype) technology
Algorithms that transform data to information
Is this information useful?
Integration with other data sources
This can improve performance
Problems: Integration of various systems, co-operation
between companies.
Decision support
With or without interference of the farmer
This is the ultimate of precision dairy farming
24. Cost efficiency
Benefits > costs
Sounds easy but ......
● Costs are clear
● Benefits often indirect
● Belief of effect
● .........
There are a few economic analyses (scientifically)
published
Portfolio problem: other fields of investment in
comparison to precision dairy

47. Use of sensor information is limited
(Hogeveen et al., 2013)
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%)
48. Many mastitis cases are not detected
(Hogeveen et al., 2013)
75%
less clinical mastitis
and higher SCC
49. Use of sensor information is limited
22% of farm owners indicated that expectations did not
match performance reality
24% of farm owners indicated
that learning support was not
as expected
(Eastwood et al., 2015)
50. Too much information without knowing
what to do with it (Russell and Bewley, 2013)

51. Farmers’ attitude is important
Being in control Letting-go
Convenience seekersBusiness optimisers
52. Farmers’ attitude
Eager to understand and
learn the system
Not having the
time or skills
Innovators/ambassadors
53. Sensors can pay for themselves…..
….. and at the same time:
Improve dairy cattle health and welfare
Improve the efficiency in the dairy value chain
All sensors?
I am not sure about that
