1 Does technology pay for itself? Henk Hogeveen, Wilma Steeneveld, Mariska vd Voort and Claudia Kamphuis
2 What can you expect from me A little history and overview Success factors for precision technology Adoption of sensor systems Effects of mastitis detection systems Effects of estrus detection systems Wrap up
3 Initiated by cow identification systems in 1970s Recording of individual milk yield Allocating feed/concentrates to individual cows
4 Boosted by development of automatic milking systems in 1980s
5 Automatic milking systems are marketed since main brands
6 Boosted by development of automatic milking systems in 1990s 1992 first commercial farm in NL (Bottema, 1992) >10,000 farms globally (Rodenburg, 2013) 3,615 (19.5%) Dutch farms (Stichting KOM, 2015)

10 Sensor development was boosted by Automatic milking Replacement of human senses
11 And further pushed by other factors Government Mom, where does the milk come from? Increasing herd seize From the factory, honey Society
12 There are A LOT of sensor technologies 12
13 Electrical Conductivity Cheap technology Low in maintenance costs Udder or quarter level In-line handheld Most used to detect abnormal milk or mastitis Limited performance for mastitis detection (Rutten et al., 2013)
14 Other (more sophisticated and expensive) sensor technologies were introduced to monitor cow health and productivity Udder Health - Electrical Conductivity - Milk yield - Somatic Cell Count - (Milk) Temperature - Colour
15 Other (more sophisticated and expensive) sensor technologies were introduced to monitor cow health and productivity Udder Health - Electrical Conductivity - Milk yield - Somatic Cell Count - (Milk) Temperature - Colour Milk Composition - Milk yield - Fat and protein content - Lactose content - Somatic cell count
16 Other (more sophisticated and expensive) sensor technologies were introduced to monitor cow health and productivity Fertility - Progesterone - Activity - Rumination Milk Composition - Milk yield - Fat and protein content - Lactose content - Somatic cell count
17 Other (more sophisticated and expensive) sensor technologies were introduced to monitor cow health and productivity Fertility - Progesterone - Activity - Rumination Cow Composition - Weight - Body Condition Score
18 Other (more sophisticated and expensive) sensor technologies were introduced to monitor cow health and productivity Metabolic disorders - Activity - Rumination - Milk yield - SCC - ph Cow Composition - Weight - Body Condition Score
19 Other (more sophisticated and expensive) sensor technologies were introduced to monitor cow health and productivity Metabolic disorders - Activity - Rumination - Milk yield - SCC - ph Cow Mobility - Weight - Activity - Rumination - Milk yield
20 There is A LOT of potential Improved health, welfare Increase productivity Increased efficiency Improved product quality Objective monitoring Improved social lifestyle..
21 What can you expect from me A little history and overview Success factors for precision technology Adoption of sensor systems Effects of mastitis detection systems Effects of estrus detection systems Wrap up
22 Success factors System specifications Cost efficiency Non-economic factors
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
25 Non-monetary factors Risk Availability of labor/capital Farmers goals/preferences
26 What can you expect from me A little history and overview Success factors for precision technology Adoption of sensor systems Effects of mastitis detection systems Effects of estrus detection systems Wrap up
27 Use of sensor systems in the Netherlands Questionnaire study: 1,672 Dutch dairy farmers (Accon- AVM) 512 (31%) responded 212 had sensor systems (41 %) Permission to use MPR data: 414 (37 % with sensors) Available accountancy data: 217 farms Steeneveld et al., 2015, J. Dairy Sci. Steeneveld & Hogeveen, 2015, J. Dairy Sci Steeneveld et al., 2015, COMPAG

45 What can you expect from me A little history and overview Success factors for precision technology Adoption of sensor systems Effects of mastitis detection systems Effects of estrus detection systems Wrap up
46 Difference between theory and practise The potential of sensors is not always reached Why??
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 flakes on filter (28%) No deviation in yield (19%) Repeatedly on list (10%) Malfunctioning (4%) Too busy (10%) 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) 50
51 Farmers attitude is important Being in control Letting-go Business optimisers Convenience seekers
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
