Antimicrobial use policy change in pre-weaned dairy calves and its impact on antimicrobial resistance in commensal Escherichia coli: a cross sectional and ecological study. Afema, J.A., Davis, M.A. and W.M. Sischo. 2019. BMC Microbiology 19: 217 (14p.)

In Significant Impact Groups: AMU reduction strategies \ Legislation and incentives; Prudent use AB
Species targeted: Dairy;
Age: Young;

Summary:
Based on feedback and interaction between study investigators, farm management and consulting veterinarians, a new policy was implemented to reduce antimicrobial use in calves. We investigated the effects of these policy changes in antimicrobial use on resistance in commensal Escherichia coli. In general, there was a declining trend in resistance to most antimicrobials during and after policy changes were implemented, except for ampicillin, ciprofloxacin, ceftiofur and gentamicin.

Summary:
RefA²vi: Towards the formalization of a French professional reference network on the use of antibiotics atpoultry farms level.Currently poultry production organizations are committed to defining an indicator monitoring the reasoned use of antibiotics. That is why, the French Poultry Institute (ITAVI), with the French poultry’s inter-professional organizations and Anses formalize a professional network to collect computerized data on use of antibiotics at farm level (RefA²vi project). In 2014 and 2015, two surveys allowed collecting data from poultry farms in all species and production types. This work aimed to discuss then to choose with the professional actors, the more pertinent indicators for all poultry productions. Finally, partners imagined a scheme of network organization, which have been tested during a pilot phase. The computerized data on use of antibiotics recorded by poultry production organizations will be sent to CIPC-CIDEF- CICAR for anonymization and aggregation, in order to send them at ITAVI, which will calculate the exposure indicators following a proven method defined with Anses. ITAVI will ensure the network’s animation (newsletter, organization of steering committee meetings).

Species targeted: Pigs; Poultry;
Age:
Summary:
This manual is intended to assist in using antibiotics in a prudent and medically efficient way without loss in productivity. The prudent and medically effective use of antibiotics comprises several elements: a) Phasing out use of antibiotics as growth promoters and avoiding regular preventive use of antibiotics; b) Avoiding use of the Highest Priority Critically Important Antimicrobials (CIAs) for human medicine in animals and adhering to the OIE List of Antimicrobials of Veterinary Importance; c) Only using antibiotics based on a diagnosis of disease by a veterinarian or other animal health professional and only for authorized indications; d) Striving for individual treatment of animals with the correct dose and duration and avoiding using antibiotics for group treatments except for poultry flocks, especially via feed. e) Using only quality-assured pharmaceuticals and always consulting an animal health professional before use; f) Disposing of unused and expired antibiotics in a proper way.

Farmer perceptions of dairy farm antibiotic use and transport pathways as determinants of contaminant loads to the environment by Georgakakos C.B., Hicks B.J., and M. Todd Walter 2021 Journal of Environmental Management 280: 11880
In Significant Impact Groups: Prudent use AB \ Farmer; Other
Species targeted: Dairy;
Age: Not stated;
Summary:
Agricultural antibiotic contamination into milk and beef products has been considered extensively, but antibiotic transport into soil and water environments is less regulated and studied. Farmer perceptions of these transport processes are critical to understanding how antibiotics reach soils and surface waters and what management strategies can be implemented to reduce environmental antibiotic loads. We have conducted semi-structured interviews with twenty-seven dairy farmers in central New York to understand farmer perceptions of environmental transport of antibiotics and decisions that reduce environmental antibiotic loads. Interviews were qualitatively analyzed and coded using thematic analysis. We found that farmers extensively considered transport of antibiotics into milk and beef, while consideration of antibiotic transport into manure was less common, and no farmers discussed antibiotic transport from carcasses into soil from on-farm animal mortality. Farmers highlighted decisions that reduce antibiotic environmental loads through disease prevention actions, usage of non-antibiotic treatments, and culturing bacterial samples before antibiotic treatment. Farmers did not cite reduction of environmental antibiotic loads as a driver of their waste management decisions. Farmers perceived antibiotic usage was already minimized on farms in the region, suggesting future environmental antibiotic contamination mitigation strategies should focus on waste management pathways.

French dairy cows’ dry period: state of play 2015-2017 by Roussel, D. Ballot, N., Gautier, P., Bore, R. and J. Jurquet 2020 Rencontres Recherches Ruminants 2020: Session Santé
In Significant Impact Groups: Prudent use AB \ Farmer; Pathogen management

Age: Adult;
Summary:
This study deals with the dry period of dairy cows. Its objective is to describe the current practices of French dairy farmer and to identify their needs as well as those of advisers in terms of technical advice on this phase of production cycle. It is based on an analysis of the national database of 2,914,921 dry cows from 2015 to 2017 and on two surveys. The first one, online, was conducted among 130 advisors from the main French dairy regions (73,8% advisers, 17,5% team supervisors and 8,7% veterinarians). The second, on farm, involved 79 farmers in Western and Eastern France. From 2015 to 2017, the median duration of the dry period was 63 days. The median milk production before drying off amounts to 16.9 kg / d with 9% of the cows over 25 kg / d. Epidemiological data show that the average new infection index in 2017 is 12% and the recovery index is 77%. But there are strong differences in results between farms which seem more linked to a herd effect than to individual effects (milk production/ cell count / drying period / …). Drying off and dry period practices are very diverse: five major treatment protocols to dry off are used. In addition, 78% of farmers use an antibiotic for drying off and 50% practice selective treatment. Similarly, 138 feeding programs are used, i.e. 1.7 per farm on average. Udder infections and milk fevers are the 2 main peripartum problems cited by 72% and 54% of farmers, respectively. The concerns of advisors relate primarily to: (i) feeding management (21%), treatment strategy (20%) and the decrease in milk production (19%) before dying off, ( ii) on dry-off protocols (47%) on the day of dry-off and (iii) on feeding and preparation for calving (39%) Farmers express similar themes. However, the nature of the information requested differs between farmers and advisors: farmers request more protocols whereas advisors ask for more basis of understanding.

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.

Summary:
A better understanding of veterinary students’ perceptions, attitudes, and knowledge about antimicrobial stewardship and biosecurity could facilitate more effective education of future veterinarians about these important issues. A multicenter cross-sectional study was performed by administering a questionnaire to veterinary students expected to graduate in 2017 or 2018 in all Australian veterinary schools. Many students were unaware of the high importance of some veterinary drugs to human medicine, specifically enrofloxacin and cefovecin. Fewer than 10% of students would use appropriate personal protective equipment in scenarios suggestive of Q fever or psittacosis. Efforts need to be made to harmonize preclinical and clinical teaching, and greater emphasis is needed on appropriate biosecurity and antimicrobial stewardship.
