Simple Summary Foot diseases are a widespread issue in dairy herds that lead to economic losses and cow welfare alteration. Time is a limited key resource for farmers in herd management and especially for the control of lameness. The aim of this study is to determine the most effective time to be allocated for digital dermatitis management and to q...

La contribution relative de l’usage des antibiotiques en production animale sur la baisse de l’efficacité des antibiotiques utilisés en médecine humaine reste mal documentée, mais l’importance de ce problème de santé publique requiert de réduire leur usage. Le plan Ecoantibio 1, mis en œuvre entre 2012 et 2016, consiste en une approche volontaire c...

Foot disorders are costly health disorders in dairy farms, and their prevalence is related to several factors such as breed, nutrition, and farmer's management strategy. Very few modeling approaches have considered the dynamics of foot disorders and their interaction with farm management strategies within a holistic farm simulation model. The aim o...

Simple Summary The present work proposes an original approach for antimicrobial (AM) resistance reduction based on marginal abatement cost. The optimal use of AMs for dairy cows is defined, and the costs of decreasing antimicrobial use (AMU) below the optimal level and increasing AMU above the optimal level are assessed. Abstract Maintaining udder...

To respond to the antimicrobial resistance (AMR) threat, public health entities implement policies aiming to reduce antimicrobial use (AMU) in livestock systems, in which policy success and sustainability might be subject to the social acceptability of the novel regulatory environment. Therefore, consistent methods that gather and synthesize prefer...

On 11 March 2020, the World Health Organization declared a pandemic of the COVID-19 coronavirus disease that was first recognized in China in late 2019. Among the primary effects caused by the pandemic, there was the dissemination of health preventive measures such as physical distancing, travel restrictions, self-isolation, quarantines, and facili...

Bioeconomic models applied to animal health issues are now commonly observed in literature. This section of literature is very heterogeneous and the underlying methods are very diverse, from very simple methods (partial budgeting) to very complex ones. The objective of the present study is to build a new dynamic stochastic optimisation bioeconomic...

The provision of healthcare by veterinarians consists of a blend of activities ensuring welfare for animals. It also contributes in the control of infectious diseases and food safety. In general practices, most of the activities generate incomes for veterinarians, notably acts (consultations, surgery, etc.) and sales (drugs, pet food, etc.). Increa...

In France, veterinarians can both prescribe and deliver veterinary medicines, which is a questionable situation from the perspective of antimicrobial use (AMU) reduction to avoid antimicrobial resistance (AMR). This situation places veterinarians in direct commercial relationships with the pharmaceutical industry as purchase contracts are signed be...

Increased size of veterinary practices and the arrival corporate practices modifies the veterinary landscape in many countries. This enables economies of scale for drugs or pet food purchases, overall improving the profitability. Working time per act is a key driver of profitability for firms with high human resources such as veterinary practices....

As of mid-2020, eradicating COVID-19 seems not to be an option, at least in the short term. The challenge for policy makers consists of implementing a suitable approach to contain the outbreak and limit extra deaths without exhausting healthcare forces while mitigating the impact on the country's economy and on individuals' well-being. To better de...

L’évaluation économique en élevage doit être vue comme une aide à la prise de décision sanitaire. Dans le cas des boiteries en élevage, il s’agit de bien comprendre l’impact global pour l’industrie laitière, pour prioriser les actions de développement et de sensibilisation du monde de l’élevage, ainsi que d’aider à la prise de décision en élevage,...

In France, veterinarians are allowed to both prescribe and deliver drugs, a questioned situation from the perspective of antimicrobial use (AMU) reduction in order to ovoid AM resistance (AMR). This situation places veterinarians in direct commercial relationships with the pharmaceutical industry. The present study aims to describe contracts betwee...

The rising public health threat of antimicrobial resistance, the influence of food service companies, as well as the overall lack of positive image of using medical products in intensive farming are major drivers curbing antimicrobial use. In the future, government policies may affect practices of antimicrobial use in beef production in feedlots, a...

Antimicrobial resistance (AMR) is a global public health threat driven by a combination of factors, including antimicrobial use (AMU) and interactions among microorganisms, people, animals and the environment. The emergence and spread of AMR in veterinary medicine (AMR-V) arising from AMU in veterinary medicine (AMU-V) can be linked to individuals'...

The literature contains an extensive panel of studies focusing on the costs of animal diseases. The losses of an agriculture holding can be influenced by many factors since farming is a complex system and diseases are closely interrelated. Meta-analysis can be used to detect effects (i.e., change in clinical mastitis losses here) across studies and...

French veterinarians are authorised to both prescribe and deliver drugs. This situation of conflict of interest is sometimes denounced as a potential source of over-prescription and overuse of veterinary antimicrobials, even if no evidence is available up to now. This leads to regular calls for separating prescription from drug delivery, even if th...

L'usage des antibiotiques (UAB) en santé animale comme en santé humaine entraine la sélection de bactéries résistantes. Leur transmission à l'homme par contact direct ou via la chaine alimentaire constitue un risque de santé public, qui a conduit à la mise en place de politiques publiques visant à réduire l'UAB. Toutefois, les évaluations socio-éco...

Les populations rurales dans les zones arides sont souvent confrontées à des pressions démographiques et climatiques qui impactent leur sécurité alimentaire, leurs revenus réels mais également les ressources naturelles. En réponse à ces pressions, la plupart des politiques agricoles de développement au niveau de ces zones ont été basées sur l'inten...
