“…This study shows that for HPCIAs, the calculated number of defined daily doses was 21% of the overall consumption. Similar results with similar measuring methods have already been shown in earlier studies, which could also demonstrate the potential for reduction over time ( 10 , 39 ). Similarly to the deviations observed for the different age categories, the lower percentage of 7% HPCIAs measured as active ingredients shows the differences in output between the two measurement methods of defined daily doses and amount of active ingredients.…”

In the Swiss pig sector, the usage of antimicrobials has been recorded, evaluated and systematically reduced on a voluntary basis since 2015. This monitoring has been carried out using various methods thereby enabling continuous national scrutiny as well as international comparisons. To gain a better understanding of the dynamics of the antimicrobial usage on Swiss farms, consumption data of farrow-to-finish farms were analyzed for (i) the within-herd relationships among different age categories and (ii) the influence of the herd size. The data were collected on 71 farms for the year 2017, encompassing the amount of active ingredients and number of defined daily doses Switzerland (nDDDch) in total, and stratified for the different age categories of piglets, weaners, fattening pigs, and sows. The differences in nDDDch per animal among the age categories were determined by a Wilcoxon test and subsequent post-hoc analysis according to Bonferroni. The within-herd relationship among the individual age categories as well as the influence of the herd size on nDDDch per animal measured as kept sows were analyzed by simple linear regression. The evaluation of the treatment days showed that 50% of the nDDDch were used in piglets, 44% for weaners, and 3% each for fattening pigs and sows. Compared to the other age categories, the examination of the number of nDDDch per animal showed a significantly higher number for sows, whereas for fattening pigs the number was significantly lower (P < 0.01). The farm-based analysis using linear regression showed a relationship between antimicrobial usage in sows and piglets (P < 0.001; adj. R2 = 0.19). Similarly, a significant relationship between larger herd size and increased antimicrobial usage was observed (P = 0.02; adj. R2 = 0.06). The present study provides an insight into the antimicrobial treatment dynamics of farrow-to-finish farms. In particular, the age categories piglets and sows—with their higher number of treatment days in total or per animal—are of interest regarding the potential reduction in antimicrobial usage. Likewise, larger farms with higher management requirements were found to be of particular importance for the reduction of antimicrobial usage. Monitoring programs should therefore evaluate different age categories separately to identify problems for individual farms.

“…This might result in a selection bias in the study population and could compromise the internal validity of the analyses in this study. Although participation in the program is without benchmarking or consequences, a reduction of AMU on farms could be observed as a result of the comparison to other farms ( 39 ).…”

“…The analysis showed that HPCIAs represented 2.6 % of the global TI usage. This percentage is lower than in 2017 (3.6 %) and 2016 (4.2 %) [7]. Nevertheless, this does not mean that the quantity of HPCIAs used in 2020 is significantly lower, because the indicators used in both studies to quantify AMU are different [17][18].…”

“…This AMU monitoring system is coupled with the Health Programmes of the Swiss Pig Health Service of SUISAG and Qualiporc. One of the main objectives of the programme is to foster prudent use of antimicrobials and to increase transparency [7]. The number of farms participating in this programme is steadily increasing.…”

“…By May 2021, more than 3100 Swiss pig farms took part in the programme and another 1400 farms had made a contract and were waiting to be included (SUISAG, personal communication), in total representing about 80 % of Swiss pig farms. A recent study conducted in 291 participating farms showed a significant reduction in the usage of antimicrobials in fattening pigs on high-usage farms between 2016 and 2017 [7].…”

Objective The aim of this study was to analyze antimicrobial usage (AMU) in fattening pig farms that took part in the SuisSano/Safety + Health Programme in Switzerland over the year 2020 and to discuss the potential for further improvement. Usage was examined according to the antimicrobial’s class and indication for use, with emphasis on highest priority critically important antimicrobials (HPCIAs). Methods Data on AMU from 1411 farms, reported in an electronic treatment journal, was used. AMU was quantified through treatment incidence (TI) based on Swiss Defined Daily Doses (DDDch). Indication of use for each antimicrobial class was analyzed with particular focus on HPCIAs. Results The total TI of all antimicrobials used in the farms corresponds to 8.9 DDDch per 1000 pig-days at risk, of which HPCIAs represented 2.6 %. A total of 140 farms (9.9 %) partake in HPCIAs usage, with tylosin (73.8 % of total HPCIA TI) and colistin (22.8 % of total HPCIA TI) being the most frequently antimicrobials used. The most common indication for treatment with HPCIAs was gastrointestinal disorders (62.1 % of total HPCIA TI). Conclusion and clinical relevance This study shows that the efforts made in recent years to foster prudent use of antimicrobials and, especially HPCIAs in Swiss pig production, have been successful. Indeed, 90.1 % (1271 of 1411) of the farms did not use any HPCIAs over the year 2020. Of the recorded treatments, HPCIA’s represented only 2.6 % of the total TIs used in fattening pigs. Since many farms do not use any HPCIAs, knowledge can be obtained from these farms to identify practices which can further reduce or even stop HPCIAs usage. Moreover, information concerning indications for HPCIAs usage provide input concerning where treatment options other than HPCIAs should be explored by both farmers and veterinarians.
