Species targeted: Poultry;
Age: Different for different species;
Summary:
The RefA²vi network is a French national network whose objective is to produce regular references on antibiotic exposure indicators calculated on the basis of a common method and measured for each poultry species, in particular turkeys and broilers. This approach is complementary to the ALEA published each year by Anses-ANMV. The methods used to calculate the RefA²vi indicators are based on the ALEA method and can be adapted for each species.

490 Research report – Mc Pherson – 2019 – Benefits from cutting antibiotic use in dry cows

490 Research report
Benefits from cutting antibiotic use in dry cows by Mc Pherson L. 2019 British Dairying 2019: 50-52
In Significant Impact Groups: Pathogen management \ Managing sick animals; Targeted use of antibiotics; Prudent use AB
Species targeted: Dairy;
Age: Not stated;
Summary:
Selective Dry Cow Therapy (SDCT) is becoming more common on many dairy farms in response to increasing pressure to use antibiotics responsibly in agriculture, as well as the demands from milk buyers and supermarkets. Trials have shown that cows with no evidence of existing infection within the udder can be successfully dried off with only a teat sealant. The use of antibiotic dry cow therapy can then be targeted to only those cows with evidence of infection at dry off—usually indicated by a high somatic cell count in late lactation.

473 Research paper
Post weaning diarrhea in pigs: risk factors and non-colistin-based control strategies by Rhouma, M., Fairbrother, J.M., Beaudry, F., and A. Letellier 2017 Acta Veterinaria Scandinavica 59: 31
In Significant Impact Groups: Pathogen management \ Managing sick animals; Targeted use of antibiotics; Feed / gut health
Species targeted: Pigs;
Age: Young;
Summary:
Post-weaning diarrhea (PWD) due to Escherichia coli is an economically important disease in pig production worldwide, affecting pigs during the first 2 weeks after weaning and characterized by sudden death or diarrhea, dehydration, and growth retardation in surviving piglets. Furthermore, many stress factors associated with the weaning period, such as removal from the sow, dietary changes, adapting to a new environment, mixing of pigs from different farms and histological changes in the small intestine, may negatively affect the response of immune system and lead to an intestinal gut dysfunction in pigs.

335 Research report – Lipkens – 2019 – Selectively drying off of dairy cows impact on future performance and antimicrobial consumption

Pathogen management \ Managing sick animals; Targeted use of antibiotics; Prudent use AB
Species targeted: Dairy;
Age: Adult;
Summary:
Test-day somatic cell counts (SCC) before drying off and after calving were used to determine cow’s udder health across the dry period and to study the impact on the performance in the next lactation. Test-day data before drying off were explored to evaluate their diagnostic ability to detect noninfected cows at the time of drying off in 15 commercial dairy herds with an adequate udder health management. We confirmed that SCC information via milk recording is capable of predicting the absence of IMI with major pathogens at dry-off, yet (an estimate of) the herd prevalence of subclinical mastitis, the cow’s milk yield and parity impact the estimates of the sensitivity, specificity and predictive values to some extent. We concluded that implementing selective dry cow treatment to reduce the antimicrobial use on commercial dairy herds, using strict selection criteria and test-day information, is possible without jeopardizing udder health or milk yield.

301 Research paper – Wassink – 2010 – Footrot and interdigital dermatitis in sheep_ farmer satisfaction with current management their ideal management and sources used to adopt new strateg

In Significant Impact Groups: Pathogen management \ Managing sick animals; Targeted use of antibiotics
Species targeted: Sheep;
Age: Not stated;
Summary:
160 UK sheep farmers were asked via questionnaire about their current management for footrot sheep and their satisfaction with it. Farmers satisfied with current management reported </= 5% lameness. Farmers reported treating lame sheep within 3 days of first seeing them lame, and those with FR/ID with parenteral antibiotics. Farmers dissatisfied with their management reported >5% lameness. These farmers practised routine foot trimming, footbathing and vaccination against footrot. Whilst 89% of farmers said they were satisfied with their management of FR, >34% were interested in changing what they did. Farmers reported that ideally they would control FR by culling/isolating lame sheep, sourcing replacements from non-lames, trimming feet less, using less antibiotics and using vaccination more. Footbathing was common, linked with dissatisfaction but also listed highly as ideal management. Some of the ideal managements aligned with best practice but others contrasted with it suggesting cognitive dissonance was present.

279 Research paper – Nadas – 2016 – Antimicrobial Susceptibility Profile of Microbial Pathogens Isolated From Calves With Respiratory Diseases

In Significant Impact Groups: Pathogen management \ Managing sick animals; Targeted use of antibiotics
Species targeted: Dairy; Beef;
Age: Young;
Summary:
Respiratory disease are frequent in calves due to the weaning stress, transport and environmental changes. The aim of this study was isolate bacteria from 30 calves with respiratory disorders and test their antimicrobial susceptibility. Samples were collected from calves with respiratory disorders (nasal discharge) aged 6 to 9 weeks in 2 series, using sterile swabs. The study carried out on nasal discharge samples collected from calves with respiratory disorders and their antimicrobial profile testing led to the following conclusions: 1) Low susceptibility to Florfenicol is caused by previous treatments when this molecule was excessively used and without prior sensitivity testing. 2) Cefquinome may represent an emergency therapeutic antibiotic for respiratory infections in calves, but the administration should always be preceded by susceptibility testing of the isolates.

264 Research paper – Gery-Choquet – 2019 – Obstacles and incentives for broiler farmers to set up preventive measures against the avian colibacillosis

In Significant Impact Groups: Pathogen management \ Managing sick animals; Targeted use of antibiotics; AMU reduction strategies
Species targeted: Poultry;
Age: Not stated;
Summary:
In a context of antibiotic restraint, colibacillosis prevention in chicken farms should be maximized. This disease is commonly treated with antibiotics. Understanding the psychological and social context in which farmers operate can have an impact management of avian. With that purpose, a first survey (qualitative study) was carried out involving 14 chicken conventional production farmers. Afterwards, 75 western France farmers of replied to quantitative questionnaire based on results from the previous survey. The survey revealed that 85% of farmers had insufficient knowledge about colibacillosis. The major incentives to prevent the avian colibacillosis were the desire to improve farm income and to reduce antibiotic use. Statistical analysis showed five farmers profiles. Advice should be adapted according to these profiles : «experimented little motivated farmers», «young and independent farmers», «farmers with others priorities», «motivated with small chicken house farmers» and «risk taker farmers».

In Significant Impact Groups: AMU reduction strategies \ Monitoring and surveillance; Antibiotic use
Species targeted: Pigs; Poultry; Dairy; Beef; Sheep; Other;
Age: Young; Adult;
Summary:
The implementation of the EcoAntibio plan aimed at reducing the risks of antibiotic resistance has led to a strong mobilization of the various partners in the cattle breeding and agricultural profession in the cattle industry. Actions have been carried out at different scales and research work conducted, particularly in the human and social sciences. In addition to possible technical actions, social, psychological and economic factors influence decisions to prescribe and administer antibiotics. This article provides an overview of the work that is investigating the role of these factors in the choice to reduce antibiotic use in livestock production, at the level of the farmer, in his relationship with the veterinarian and livestock advisors, and more broadly in its professional and economic environment.

185 Research paper – Sjolund – 2016 – Quantitative and qualitative antimicrobial usage patterns infarrow-to-finish pig herds in Belgium France Germany and Sweden

In Significant Impact Groups: AMU reduction strategies \ Monitoring and surveillance; Antibiotic use
Species targeted: Pigs;
Age: Young; Adult;
Summary:
The aim of this study was to compare antimicrobial usage for pigs by age category, antimicrobial class and administration route for farrow-to-finish herds in four EU countries. A cross-sectional study was conducted among 227 farrow-to-finish pig herds in Belgium, France, Germany and Sweden. The Swedish herds had the lowest and the German herds the highest overall use. Most treatments were applied to weaned piglets except in the Swedish herds (with more frequent treatment of suckling piglets). Antimicrobials were most often applied through feed or water except in the Swedish herds where parenteral treatments were most frequent. Aminopenicillins was the antimicrobial class most commonly used. Belgian herd use of third and fourth generation cephalosporins was higher compared to the other countries. In summary, there were large differences in antimicrobial use for pigs between countries, herds and age groups in farrow-to-finish herds of similar size.
