AMU reduction strategies \ Monitoring and surveillance; Antibiotic use
Species targeted: Pigs;
Age: Young; Adult;
Summary:
The purpose of this study was to understand the major areas of reduction in antibiotic use over six years, through the INAPORC panels, which were surveys of representative samples of farms performed in 2010, 2013 and 2016. Over the six years, the mean number of treatment days significantly decreased for all age categories of animals. However, for sows the decrease was less marked (-7%) than for suckling piglets (-28%), weaned piglets (-70%) and fatteners (-71%). Other major results included a considerable decrease in the use of critically important antibiotics (kept in priority for human medicine), premixes and colistin. This did not result in increased use of other digestive antibiotics or in a massive use of zinc oxide (16% of farms using zinc oxide in 2016). The INAPORC panel contributes to providing detailed references on antibiotic use in pig production and demonstrates the continued commitment to improving current practices.

In Significant Impact Groups: Biosecurity \ Pathogen management
Species targeted: Pigs;
Age: Young; Adult;
Summary:
This study aimed at assessing possible associations between the biosecurity level, antimicrobial usage and farm and production characteristics in order to advice on best practices for a low antimicrobial usage and maximum animal health and production. A cross-sectional study was conducted in 227 farrow-to-finish pig herds in Belgium, France, Germany and Sweden between December 2012 and December 2013. Associations between biosecurity status, antimicrobial usage, and production parameters were evaluated. This study showed that the antimicrobial usage in breeding animals tends to be positively associated with the number of weaned piglets per sow per year and the antimicrobial usage from birth to slaughter (TI 200) in growing pigs. The TI 200 was lower in herds with a farrowing rhythm ≥5- weeks, a higher biosecurity status and tended to be lower with weaning of the piglets at an older age.

In Significant Impact Groups: Biosecurity
Species targeted: Pigs;
Age: Young; Adult;
Summary:
This study aimed at assessing the levels of implementation of biosecurity measures in pig production to describe possible associations between the biosecurity level and farm and production characteristics. The study was conducted in 232 farrow-to-finish pig herds in Belgium, France, Germany and Sweden, between December 2012 and December 2013. The biosecurity status in each of these herds using Biocheck.UGent. The results showed that the biosecurity on many pig farms was low. Internal and external biosecurity levels differed between countries. The external biosecurity status was highest in Germany and lowest in France. The internal biosecurity status was highest in Sweden and lowest in Belgium. External biosecurity scores were in general higher than internal biosecurity scores. Herds with more sows and more employees were likely to have a higher external biosecurity score. A higher external biosecurity positively influenced the number of weaned piglets per sow per year and the internal biosecurity score.

165 Research paper – Postma – 2015 – Assigning defined daily doses animal_ a European multi-country experience for antimicrobial products authorized for usage in pigs

In Significant Impact Groups: AMU reduction strategies \ Monitoring and surveillance
Species targeted: Pigs;
Age: Young; Adult;
Summary:
This study aims to define an agreement to daily dose animal (DDDA) for each active substance (AS) and administration route for swine antimicrobials authorized in four European countries, thus allowing cross-country quantification and comparison of antimicrobial usage data. All veterinary antimicrobial products authorized for swine use in Belgium, France, Germany and Sweden were listed per administration route. This study presents an agreement DDDA list for use in the quantification and comparison of antimicrobial use. Four major recommendations are: (i) urgent need for harmonization of authorization and recommended summary of product characteristics (SPC) dosages; (ii) expand the developed preliminary DDDA list to include all authorized veterinary medicinal products in all EU member states and for all (food-producing) animal species; (iii) improved accessibility of country-specific SPC data would be preferable; and (iv) statement of the ‘long-acting’ duration of a product in the SPC.

135 Research paper – Raasch – 2020 – Effectiveness of alternative measures to reduce antimicrobial usage in pig production in four European countries

In Significant Impact Groups: Specific alternatives \  AMU reduction strategies
Species targeted: Pigs;
Age: Young; Adult;
Summary:
The reduction of antimicrobial usage (AMU) is in the focus in modern pig production. The objective of this study was to assess the effectiveness of alternatives to reduce AMU at herd level. In a study, 68 farrow-to-finish pig herds located in Belgium, France, Germany and Sweden were recruited on a voluntary basis to implement tailor-made intervention plans to reduce AMU. Alternative measures included improvement of biosecurity, vaccination, changes of feeding schemes or drinking water quality, improved pig health and welfare care as well as changes in stable climate and zootechnical measures. Following tailor-made implementation of alternative measures, a substantial reduction of AMU in pig production was achievable without jeopardizing animal health. The AMU reduction in the youngest age categories (suckling and weaned pigs) and the reduction of group treatments via feed and water was in line with the recent European Guidelines on the prudent use of antimicrobials in veterinary medicine.

134 Research paper – Collineau – 2017 – Profile of pig farms combining high performance and low

In Significant Impact Groups: Biosecurity \ Pathogen management
Species targeted: Pigs;
Age: Young; Adult;
Summary:
Pig farmers have been advised to reduce their antimicrobial usage because of the threat of antimicrobial resistance. This study investigates the profile of ‘top-farms’, which combine both high technical performance and low antimicrobial usage. A study was conducted among 227 farrow-to-finish farms in Belgium, France, Germany and Sweden. Within this study, 44 top-farms were compared with the ‘regular’ farms in terms of farm characteristics, biosecurity and health status. Top-farms had fewer gastrointestinal symptoms in suckling pigs and fewer respiratory symptoms in fatteners, which could partly explain their reduced need for antimicrobials and higher performance. They also had higher biosecurity and were located in sparsely populated pig areas. However, 14 farms of the top-farms group were located in densely populated pig areas, but they had higher internal biosecurity and more extensive vaccination against respiratory pathogens. These results illustrate that it is possible to control infectious diseases with low antimicrobial usage.

132 Research paper – Collineau – 2018 – Application of multiblock modelling to identify key drivers for antimicrobial use in pig production in four European countries

In Significant Impact Groups: Pathogen management \ Biosecurity
Species targeted: Pigs;
Age: Young; Adult;
Summary:
Antimicrobial use in pig farming is influenced by a range of risk factors, including herd characteristics, biosecurity level, farm performance, occurrence of clinical signs and vaccination scheme, as well as farmers’ attitudes and habits towards antimicrobial use. So far, the effect of these risk factors has been explored separately. This study aimed to investigate the relative importance of all these risk factors in a sample of 207 farrow- to-finish farms from Belgium, France, Germany and Sweden. The occurrence of clinical signs, especially of respiratory and nervous diseases in fatteners, was one of the largest contributing risk factors in all four countries, whereas the effect of the other risk factors differed between countries. In terms of risk management, it suggests that a holistic and country-specific mitigation strategy is likely to be more effective.

AMU reduction strategies \ Monitoring and surveillance; Antibiotic use; Prudent use AB
Species targeted: Other;
Age: Different for different species;
Summary: The current threat of antimicrobial resistance plus the need to control it and find alternatives to currently used antimicrobial products has prompted the different stakeholders to take action in integrating research and public health, maintaining and promoting national and international antimicrobial resistance (AMR) research communities. In summary, the following measures can be taken to prevent emergence and spread of AMR: rational antibiotic’s use, implementing infection control measures at farm level, developing strategies to mitigate the risks for environment of antimicrobial residues, having rapid tests for diagnosis of infections, promotion of research on prevention and surveillance of AMR and developing novel antimicrobial strategies and agents, improving general and public awareness of responsible antibiotic use and risks associated to increased AMR.

128 Research paper – Collineau – 2017 – Herd-specific interventions to reduce antimicrobial usage in pig production without jeopardising technical and economic performance

Biosecurity \ Pathogen management
Species targeted: Pigs;
Age: Young; Adult;
Summary: Pig farmers are strongly encouraged to reduce their antimicrobial usage in order to reduce the risk of antimicrobial resistance. Herd-level intervention is needed to achieve reduction targets. The objective of this study was to asses feasibility, effectiveness and return on investment these interventions aiming at reducing antimicrobial usage in pig production. An intervention study was conducted in 70 farrow-to-finish pig farms located in Belgium, France, Germany and Sweden. Following interventions, a reduction in antimicrobial use was achieved without negative impact on the technical performance. Mortality in suckling piglets, weaners and fatteners, daily weight gain and feed conversion ratio did not significantly change during the study, while the number of weaned piglets per sow per year slightly increased. Median change in net farm profit was overall positive. Costs of alternative measures are therefore not a barrier, but an opportunity to optimize production practices for sustained productivity and improved animal health.
