[Influence of personal attitude of the manager on antibiotic use in pig production]. / Einfluss der persönlichen Einstellung des Betriebsleiters auf den Antibiotika-Verbrauch in der Schweineproduktion.

The attitude as well as the expertise of a person affect the behavior and actions in daily life. To investigate the influence of attitude and knowledge of pig producers on the use of antibiotics in farms, 220 Swiss pig producers were questioned on health awareness, attitude towards sustainable production, risk behavior, intrinsic motivation and knowledge about antibiotics and resistance development. In addition, the strategy of antibiotic use (therapeutic or prophylactic) and the business practice (single or group therapy) for the amount of antibiotics on one hand and for the risk of antibiotic resistance development on the other hand, were determined in a personal interview. Farmers using antibiotics only therapeutically had a better business practice. A direct link between the personal attitude and the antibiotic use or a higher risk of development of antibiotic resistance was not found in this investigation.

[Risk factors for the oral use of antibiotics and animal treatment incidence of weaners in Switzerland]. / Risikofaktoren für den oralen Einsatz von Antibiotika und Tierbehandlungsinzidenz bei Absetzferkeln in der Schweiz.

In the present study, risk factors for the use of oral antibiotics in weaned piglets were collected on 112 pig farms by a personal questionaire. The most common indication for an antibiotic group therapy was diarrhoea, and the most frequently used antibiotic was Colistin. On average, 27.33 daily doses in the control farms and 387.21 daily doses in the problem farms per 1000 weaners were administered on a given day. The significant risk factors in the multivariate model were poor hygiene in the water supply of suckling piglets, less than two doses ofprestarter feed daily, lack of an all-in-and-all-out production system in weaners, no herd book performance data analysis, and less than two of the legally prescribed veterinary visits per year. Furthermore, the treatment incidence of weaners for oral antibiotics was calculated on the basis of the drug inventory. This study provides evidence that the use of oral antibiotics in weaners can be reduced by interventions in hygiene and management.

INTRODUCTION: In the present study, risk factors for the use of oral antibiotics in weaned piglets were collected on 112 pig farms by a personal questionaire. The most common indication for an antibiotic group therapy was diarrhoea, and the most frequently used antibiotic was Colistin. On average, 27.33 daily doses in the control farms and 387.21 daily doses in the problem farms per 1000 weaners were administered on a given day. The significant risk factors in the multivariate model were poor hygiene in the water supply of suckling piglets, less than two doses of prestarter feed daily, lack of an all-in-and-all-out production system in weaners, no herd book performance data analysis, and less than two of the legally prescribed veterinary visits per year. Furthermore, the treatment incidence of weaners for oral antibiotics was calculated on the basis of the drug inventory. This study provides evidence that the use of oral antibiotics in weaners can be reduced by interventions in hygiene and management.

INTRODUCTION: Pour la présente étude, on a relevé, sur la base d'une enquête personnelle dans 112 exploitations d'élevage, les facteurs de risque relatifs à l'usage d'antibiotiques oraux chez les porcelets sevrés. L'indication la plus fréquente pour un traitement antibiotique de groupe était la diarrhée et l'antibiotique le plus fréquemment utilisé la colistine. En moyenne on utilisait 27.33 doses journalières pour 1000 porcelets par jour dans les exploitations de contrôle et 387.21 dans les exploitations à problèmes. Dans un modèle à variables multiples, on a identifié en tant que facteurs de risques une mauvaise hygiène d'abreuvement, l'absence de distribution ou une distribution inférieure à 2 fois par jour d'aliments préstarter, une charge continuelle dans la porcherie de sevrage, l'absence d'utilisation des données de production du herdbook et un nombre de visite de contrôle en matière de médicaments vétérinaire par le vétérinaire d'exploitation inférieur aux deux visites annuelles prescrites. On a en outre calculé, sur la base des listes d'inventaire de l'exploitation, l'incidence des traitements des porcelets sevrés avec des antibiotiques oraux. Ces résultats démontrent que des interventions au niveau de l'hygiène et du management permettent de réduire l'usage d'antibiotiques oraux dans les porcheries de sevrage.
