Abstract

Background: In 2015, in Switzerland the Suissano Health Programme was implemented in pig production to improve transparency for antimicrobial usage (AMU) and to reduce the usage of fluoroquinolones (FQ), macrolides and cephalosporins, representing highest priority critically important antimicrobials.

Methods: In the presented cohort study, the impact of the Suissano programme on the AMU of 291 pig farms between 2016 and 2017 was investigated. AMU was calculated in total numbers of defined course doses (nDCDch) for all farms in the programme. For each single farm the nDCDch/animal/year was determined for four different age categories (suckling piglets, weaned piglets, fattening pigs, sows) as well as each antimicrobial substance separately. Trends between 2016 and 2017 were investigated for all farms as well as the 25 per cent with the highest usage of antimicrobials (high users) separately.

Results: Total AMU measured in nDCDch declined by 23 per cent between 2016 and 2017, but statistically significant differences could not be observed when comparing the data sets of the individual farms. A significantly reduced usage of FQ could be demonstrated in suckling piglets (P=0.003), weaned piglets (P=0.006) and sows (P=0.008) in 2017 compared with 2016. For high users, a significant reduction of total AMU could be shown in suckling piglets (P=0.02), weaned piglets (P=0.0004) and fattening pigs (P=0.01).

Conclusion: This study demonstrated a significant reduction in the usage of FQs in suckling piglets, weaned piglets and sows as well as total AMU in suckling piglets, weaned piglets and fattening pigs on high-usage farms.

Suissano 健康计划对瑞士 291 个养猪场抗菌药使用情况的影响。

背景：2015年，瑞士在养猪生产中实施了Suissano健康计划，以提高抗菌药使用（AMU）的透明度，减少氟喹诺酮类（FQ）、大环内酯类和头孢菌素的使用，这些抗菌药代表了最优先的极其重要的抗菌药：在所提交的队列研究中，调查了 2016 年至 2017 年间 Suissano 计划对 291 个猪场 AMU 的影响。AMU 以该计划中所有猪场的规定疗程剂量总数（nDCDch）计算。对每个猪场的四个不同年龄类别（哺乳仔猪、断奶仔猪、育肥猪、母猪）以及每种抗菌物质分别确定了 nDCDch/动物/年。对所有猪场以及抗菌素使用量最高的 25%猪场（高用量猪场）2016 年至 2017 年的趋势进行了调查：2016 年至 2017 年间，nDCDch 中测得的 AMU 总量下降了 23%，但在比较各个农场的数据集时，无法观察到统计学上的显著差异。与2016年相比，2017年哺乳仔猪（P=0.003）、断奶仔猪（P=0.006）和母猪（P=0.008）的FQ使用量明显减少。对于高用量者，哺乳仔猪（P=0.02）、断奶仔猪（P=0.0004）和育肥猪（P=0.01）的总AMU显著减少：本研究表明，在高使用量猪场中，哺乳仔猪、断奶仔猪和母猪的 FQs 使用量以及哺乳仔猪、断奶仔猪和育肥猪的 AMU 总量均显著减少。
