Implications
• For the farmer– More focus on quality of production– Importance of animal health goes beyond
profit• For the veterinarian
– Less curative drug sales– On-farm counseling as part of veterinary herd
health management– VHHM is more and more stimulated
![Page 4: Associations between farmer participation in veterinary herd health programs and farm performance](https://reader035.fdocuments.net/reader035/viewer/2022062708/5589806ad8b42a101d8b46b3/html5/thumbnails/4.jpg)
“a combination of animal health, production and prevention, in a framework of economics, animal welfare, food safety,
public health and environment. Regular farm visits and checks of specific farm
data are very important.“
Definition of on-farm counseling (literature)
![Page 5: Associations between farmer participation in veterinary herd health programs and farm performance](https://reader035.fdocuments.net/reader035/viewer/2022062708/5589806ad8b42a101d8b46b3/html5/thumbnails/5.jpg)
• Very broad• Interpretation is difficult• Our definition: A regularly visit of the veterinarian
on the farm aimed at the prevention of disease. May be combined with routine activities
Limitations of this definition

A few questions
• What is the view of the farmers towards VHHM
• What is the view of the veterinarians towards VHHM
• How well is the VHHM performed?• What is the effect of VHHM• What are the economics of VHHM
![Page 11: Associations between farmer participation in veterinary herd health programs and farm performance](https://reader035.fdocuments.net/reader035/viewer/2022062708/5589806ad8b42a101d8b46b3/html5/thumbnails/11.jpg)
Why VHHM (farmers view)
• Research 2007• Questionaires for 800 farmers• Why and why not VHHM• 250 returned, 170 VHHM, 80 no VHHM
• Derks et al., 2012 (PVM)

Charging
• Per hour: 69%• Per hour (advice) and per act: 28%• Fixed tariff per cow per year: 2%• Specific packages 1%

Conclusions
• Fertility large part of activities• Farmers like the “support”• Reasons not to participate:
– Money– Time
![Page 16: Associations between farmer participation in veterinary herd health programs and farm performance](https://reader035.fdocuments.net/reader035/viewer/2022062708/5589806ad8b42a101d8b46b3/html5/thumbnails/16.jpg)

The interviews
• Semi structured interview: definition and pressure points
• 10 randomly selected practices throughout the Netherlands
• Recorded with a voice recorder and transcribed in full
• After coding connections were made
• Not published

Farmer is the key figure
• Depends on what the farmer wants (10x)• There is no protocol, it is adjusted to the
farm• I take other things into account, depending
on the farmer• You look at what is important on that farm
at that time• The farmer asks, and you deliver, that’s the
whole story
![Page 21: Associations between farmer participation in veterinary herd health programs and farm performance](https://reader035.fdocuments.net/reader035/viewer/2022062708/5589806ad8b42a101d8b46b3/html5/thumbnails/21.jpg)
Variation between farmers
• Some farmers are active participants in study groups, others aren’t, it varies
• Some don’t want that, they just want fertility checks
• I have farms that really want to look into problems, and others that absolutely don’t want that
• Some prefer to keep their production numbers to themselves
• And some are really obedient, they follow the advice, and others just… don’t
![Page 22: Associations between farmer participation in veterinary herd health programs and farm performance](https://reader035.fdocuments.net/reader035/viewer/2022062708/5589806ad8b42a101d8b46b3/html5/thumbnails/22.jpg)
But most important conclusion …
The attitude of the veterinarian towards on-farm counseling influences on-farm counseling and the way the advice is
picked up by farmers
![Page 23: Associations between farmer participation in veterinary herd health programs and farm performance](https://reader035.fdocuments.net/reader035/viewer/2022062708/5589806ad8b42a101d8b46b3/html5/thumbnails/23.jpg)
Illustration: two practices
• Interview nr. 7 and nr. 8, two practices that were situated 20 km apart
• No difference in geographical or sociological structures expected
• Large difference in attitude towards on-farm counseling
![Page 24: Associations between farmer participation in veterinary herd health programs and farm performance](https://reader035.fdocuments.net/reader035/viewer/2022062708/5589806ad8b42a101d8b46b3/html5/thumbnails/24.jpg)

Conclusion
• Big differences between practises
• Because of farmers?
• ….. or because of attitude of the vet???
![Page 26: Associations between farmer participation in veterinary herd health programs and farm performance](https://reader035.fdocuments.net/reader035/viewer/2022062708/5589806ad8b42a101d8b46b3/html5/thumbnails/26.jpg)
A few questions
• What is the view of the farmers towards VHHM
• What is the view of the veterinarians towards VHHM
• How well is the VHHM performed?• What is the effect of VHHM• What are the economics of VHHM
![Page 27: Associations between farmer participation in veterinary herd health programs and farm performance](https://reader035.fdocuments.net/reader035/viewer/2022062708/5589806ad8b42a101d8b46b3/html5/thumbnails/27.jpg)
Study on advising skills
• Study in 2011• 29 vets in 15 practises• Accompanied during 1 VHHM visit (1 vet 2
visits)• Questionnaire for vet and farmer (same
questions)• Evaluation of advisory talk
• Derks et al., 2013 (Vet J.)
![Page 28: Associations between farmer participation in veterinary herd health programs and farm performance](https://reader035.fdocuments.net/reader035/viewer/2022062708/5589806ad8b42a101d8b46b3/html5/thumbnails/28.jpg)
Setting goals
• 7 vets set goals together with farmer• not setting goals because
– Not aware of wishes of farmer– No need to commit this to writing– Documentation is ‘too formal’– No good reason to set goals
![Page 29: Associations between farmer participation in veterinary herd health programs and farm performance](https://reader035.fdocuments.net/reader035/viewer/2022062708/5589806ad8b42a101d8b46b3/html5/thumbnails/29.jpg)
Awareness of goals
• 22 combinations of ‘farmer’ and ‘veterinarian’ goals
• 16 vets could not clearly identify a farmer’s main goal
• most goals were not clearly defined• none of the farmers/veterinarians used
target values in establishing goals.

Conclusion
Vets should learn a lot about proper consulting
The value of VHHM can be greatly improved
![Page 33: Associations between farmer participation in veterinary herd health programs and farm performance](https://reader035.fdocuments.net/reader035/viewer/2022062708/5589806ad8b42a101d8b46b3/html5/thumbnails/33.jpg)

Large study
• 5,000 farms (207 vet practises) from CRV (MPR organisation)
• Questionnaire about VHHM• 695 replies (69 % VHHM)• MPR and fertility data available• Analyses on MPR data in relation to VHHM
• Derks et al., 2013, 2014 (J. Dairy Sci)

Effects VHHM
• Participation– More milk (+336 kg/cow/year)– Lower SCC (-8,340 cells/mL)– Lower first calving age ALVA (-12 d) – Lower % non return 56-d (−3.34%)– More inseminations per cow (+0.09). – More culled cows (+1.05%)– Lower age at culling (−70 d).

Yeah but ….
• There is an association no “real” causaal effect
• My belief: At least part of the effect is “real”
![Page 39: Associations between farmer participation in veterinary herd health programs and farm performance](https://reader035.fdocuments.net/reader035/viewer/2022062708/5589806ad8b42a101d8b46b3/html5/thumbnails/39.jpg)
Two studies
• Normative• Economic data• Question:
If you compare the costs of VHHM with the economic value of improvements, what is the efficiency?
• Ifende et al., 2014 (Vet Rec); Derks et al., 2014
![Page 40: Associations between farmer participation in veterinary herd health programs and farm performance](https://reader035.fdocuments.net/reader035/viewer/2022062708/5589806ad8b42a101d8b46b3/html5/thumbnails/40.jpg)
Normative study
• All farms from previous study• Look at VHHM and estimate costs
(normative)– Farm seize– Reproductive performance– Intensity of VHHM
• Calculate net returns milk production• Calculate costs of replacement
![Page 41: Associations between farmer participation in veterinary herd health programs and farm performance](https://reader035.fdocuments.net/reader035/viewer/2022062708/5589806ad8b42a101d8b46b3/html5/thumbnails/41.jpg)

Data study
• Bookkeeping firm (Alfa Accountants)• Questionnaire send to 572 farms• 187 replied (85 participants, 102 non part)• All farm economic data available• Stochastic frontier analysis
– Looking at efficiency of farms– 4 models: financial data per cow/kg milk and
including/excluding farm structure variables

No differences between groups
![Page 47: Associations between farmer participation in veterinary herd health programs and farm performance](https://reader035.fdocuments.net/reader035/viewer/2022062708/5589806ad8b42a101d8b46b3/html5/thumbnails/47.jpg)
Conclusions
• Normative study:– Clear economic benefit of VHHM
benefit/cost ratio: 4.2• Farm economic data study
