Transcription

1 PVSGEU Autumn meeting 2017 PROHEALTH: How secure is biosecurity in broilers and layers across the EU? This project has received funding from the European Union s Seventh Framework Programme for research, technological development and demonstration under grant agreement no

2 Outline of presentation: Introduction How to measure biosecurity? Results and conclusions Further activities

3 Introduction: Tommy Van Limbergen ( o Beveren-Waas, 1988) Master of Veterinary Medicine UGent => 2012 Field veterinarian: Poultry (Belgium) and pigs (The Netherlands) Since : PhD-candidate at UGent (= start PROHEALTH-project) Since : Resident at the European College for Poultry Veterinary Science (ECPVS) : Continued collaboration with Ghent University (pigs and poultry diseases and antibiotic usage) Research and Innovation manager at PErformance and HEalth STATistics (PEHESTAT)

4 Introduction: What is PROHEALTH? European project (EC nr ) To improve the understanding of the multifactorial aspects which contribute to the formation of production diseases. To help provide effective control strategies to reduce the impact of these diseases. To pool existing expertise:

5 Introduction:

6 Introduction: How do we measure animal health? On farms, we mostly do not measure animal health, but: level of management and biosecurity (absence of) disease Distinction: «infection» «disease» Different levels: animal, group, farm, region, country

7 Introduction: What about the importance of biosecurity? Poultry in EU is mainly raised in intensive conditions with large numbers of animals housed on same site Large number of animal movements within/between countries Biosecurity plans help to manage the risk of introducing new pathogens on poultry farms (E.g. AI)

8 Outline of presentation: Introduction How to measure biosecurity? Results and conclusions Further activities

9 How to measure biosecurity? Webbased tool: Based on: Scientific literature Poultry Experts opinion In-house experience FREE ACCESS => 2 versions: broilers and laying hens

10 How to measure biosecurity? Webbased tool: Takes only +/- 20 minutes Full multiple choice (easy) Instant 2 page report! => clear advices: How to improve!!!

11 How to measure biosecurity? Webbased tool: Own results (red) Database average (green) Create a log in! => Do it again and check your improvements!!!

12 How to measure biosecurity? 1) Purchase of DOC 5) Entrance 2) Depopulation 6) Material supply 3) Feed and water External biosecurity 7) Infrastructure / vectors 4)Dead animals / used litter 8) Farm location

13 How to measure biosecurity? 2) Cleaning and disinfection 1) Disease management Internal biosecurity 3) Measurements between houses

14 How to measure biosecurity? Calculation of Total biosecurity: 70 % external biosecurity 30 % internal biosecurity All categories are weighted. Example: Belgian broiler farm =>

15 How to measure biosecurity? Laying hens: Suitable for all types of housing system! Web-based tool specialy designed for PROHEALTH Same principle as broilers tool FREE ACCESS =>

16 Outline of presentation: Introduction How to measure biosecurity? Results and conclusions Further activities

17 Results: Broiler-farms 462 broiler farms visited between February and August countries included: Belgium, Cyprus, Finland, Greece, Poland, Spain, UK Quantification of biosecurity: Risk based scoring tool Online accessible:

18 Results: Broiler-farms Category / Dataset A B C D E F G Overall External biosecurity and management ) Purchase of one-day old chicks ) Depopulation of broilers ) Feed and water supply ) Removal of manure and dead animals ) Entrance of visitors and personnel ) Supply of materials ) Infrastructure and biological vectors ) Location of the farm Internal biosecurity and management ) Disease management ) Cleaning and disinfection ) Materials and methods between houses Overall biosecurity and management

19 Results: Broiler-farms External: 68.4 ( ) Internal: 76.6 ( ) Overall: 70.9 ( )

20 Results: Broiler-farms Positive correlation (Int. Ext.) Ext. Biosecurity: Best: infrastrusture and vectors Worst: visitors and staff Int. Biosecurity: Best: disease management Worst: inter-house management

21 Results: Broiler-farms Conclusions: Internal >>>> external Larger farms => lower internal biosecurity Best category: Disease management 83.8% Worst category: Entrance of visitors and staff 51.6% = easy to improve!!!!

22 Results: Layer-farms 124 layer farms visited between February and August countries included: Belgium Finland Poland Parameter / Dataset A B C Number of farms Type of housing: - Enriched cages - Deep litter system - Perchery system Average farm size Average number of FTE Number of laying hens / FTE Average number of years of experience of the farmer

23 Category / Dataset A B C Overall External biosecurity and management ) Entrance of visitors and personnel ) Location of the farm ) Infrastructure and biological vectors ) Supply of materials ) Purchase management of pullets ) Depopulation and transport of hens ) Feed and water supply ) Management of manure and carcasses Internal biosecurity and management ) Routine husbandry ) Flock health management ) Cleaning and disinfection ) Materials and measures between houses 5) Egg management Overall biosecurity and management

24 Results: Layer-farms Conclusions: Internal (71,1%) >> external (61,8%) Housing External BS Internal BS Overall BS Deep litter 59,5 68,1 63,0 Enriched cages 62,1 73,4 66,6 Perchery 63,0 70,5 66,0 Enriched cages Deep litter Perchery => Best: internal and overall biosecurity => Worst: external, internal and overall biosecurity => Best: external biosecurity Best category: Egg management 87.9% Worst category: Entrance of visitors and staff 40.6% = easy to improve!!!!

25 Overall conclusions Web-based tool = good instrument to evaluate biosecurity! - Helps to identify weak points! - Helps to design improvement-strategies! - Can be part of veterinary guidance program!

26 Overall conclusions Take home message: Internal biosecurity >> external biosecurity Broiler farms score better than layer farms Layer farms: Enriched cages: best internal and overall biosecurity Perchery system: best external biosecurity Worst category: Entrance of visitors and staff

27 Outline of presentation: Introduction How to measure biosecurity? Results and conclusions Further activities

28 Further activities To identify RISK and PROTECTIVE factors related to production diseases! 50 farms / country Tailor-made questionnaires => to cope with different aspects of production Housing (e.g.: type of ventilation) Feed and water ( e.g.: feeding space per bird) Production management (e.g.: type of lighting schedule) To be delivered => november 2017!!!
