2 The context of the stakeholder consultation Undertaken as part of EU PROHEALTH project WP 7 examined costs of pig and poultry production diseases and costs & benefits of interventions to control them Methodology 1. Systematic literature review to assess economic impact of production diseases. Identified 9 poultry production diseases based on availability of economic/physical parameter impacts data 2. Stakeholder consultation in 5 EU countries. 3. Bio-economic modelling 2

3 The goal of the stakeholder consultation Validate the outcomes of the systematic literature review Does the review: Capture the most important production diseases? Correctly estimate disease costs? Correctly estimate efficacy and cost of interventions? Identify preferred interventions to control individual diseases Identify preferred interventions to control multiple diseases 3

4 Stakeholder consultation methodology Over 350 stakeholders contacted in 5 EU countries in early producers, plus upstream and downstream stakeholders. Outputs of literature review shown to stakeholders. disease costs costs and benefit of control interventions 45 complete responses obtained response rate from Germany and Poland was low. 4

6 Did the literature review cover the most important diseases? Broilers Layers Rank Lit. review Salpingoperitonitis syndrome 1 Coccidiosis 2 Ascites Injurious pecking 3 Infectuous bronchitis Infectious bronchitis 4 Tibial dischonroplasia Coccidiosis 5 Clostridiosis Clostridiosis 6 Lameness Keel bone damage 7 Sudden death syndrome Lameness 8 Injurious pecking Foot-pad dermatitis (FPD) Foot-pad dermatitis Ascites 9 (FPD) 10 Keel bone damage Lit. review 6

7 Results for four production diseases Stakeholder rank Broiler diseases Stakeholder rank Layer diseases 1 Coccidiosis 2 Injurious pecking 2 Ascites 3 Infectious bronchitis 7

9 Broilers - coccidiosis Lit. review estimation Too high (%) About right (%) Too low (%) Impact on Net Margin -50% Cost of intervention (vaccination - coccidiostats) 120/ k birds Severe and uncontrolled form of the disease Vaccination 2 nd most preferred intervention by stakeholders No statistically significant differences between countries or stakeholder groups 9

10 Controlling ascites stakeholder view 10

11 Broilers - Pulmonary hypertension disorder (Ascites) Lit. review estimation Too high (%) About right (%) Too low (%) Impact on Net Margin -6% Efficacy of intervention (feed restriction) 8% Severe and uncontrolled form of the disease Feed restriction 2 nd most preferred intervention by stakeholders No statistically significant differences between countries or stakeholder groups 11

12 Controlling injurious pecking stakeholder view 12

13 Layers injurious pecking Lit. review estimation Too high (%) About right (%) Too low (%) Impact on Net Margin -50% Efficacy of intervention (beak trimming) 10% Severe and uncontrolled form of the disease Beak trimming not in stakeholder list of preferred interventions No statistically significant differences between countries or stakeholder groups 13

14 Controlling Infectious bronchitis stakeholder view 14

15 Layers infectious bronchitis Lit. review estimation Too high (%) About right (%) Too low (%) Impact on Net Margin -30% Efficacy of intervention (vaccination) 40% Severe and uncontrolled form of the disease Vaccination was 2 nd most preferred intervention by stakeholders No statistically significant differences between countries or stakeholder groups 15

16 Preferred interventions to control multiple diseases (poultry and pigs) 16

17 Preferred interventions to control multiple diseases (poultry and pigs) 17

18 Additional findings Commonality between countries (standardised production systems) Major emphasis on prevention measures (rather than cures) Many preferred measures common to multiple diseases Commonality between interventions for pigs and poultry The most useful overall interventions were improving: biosecurity; ventilation; and litter quality. 18

19 Validation of the literature review Strengths Captures diseases of most economic concern Estimated disease costs considered reasonably accurate Most efficacious intervention usually in the top two preferred by stakeholders Weaknesses Some stakeholders thought disease impacts were too high. Studies seldom reported economic impacts Poor coverage of some commercially useful interventions Multi-functional interventions rarely studied (esp. preventive) Reliable enough to inform policymakers & research scientists More research needed into - measures to control multiple diseases 19
