To implement effective stewardship in food animal production, it is essential that producers and veterinarians are aware of preventive interventions to reduce illness in livestock. Systematic reviews and meta-analyses (SR/MA) provide transparent, replicable, and quality-assessed overviews. At present, it is unknown how many SR/MA evaluate preventive antibiotic use or management practices aimed at reducing disease risk in animal agriculture. Further, the quality of existing reviews is unknown. Our aim was to identify reviews investigating these topics and to provide an assessment of their quality. Thirty-eight relevant reviews were identified. Quality assessment was based on the AMSTAR 2 framework for the critical appraisal of systematic reviews. The quality of most of the reviews captured was classified as critically low (84.2%,n= 32/38), and only a small percentage of the evaluated reviews did not contain critical weaknesses (7.9%,n= 3/38). Particularly, a small number of reviews reported the development of ana prioriprotocol (15.8%,n= 6/38), and few reviews stated that key review steps were conducted in duplicate (study selection/screening: 26.3%,n= 10/38; data extraction: 15.8%,n= 6/38). The development of high-quality reviews summarizing evidence on approaches to antibiotic reduction is essential, and thus greater adherence to quality conduct guidelines for synthesis research is crucial.

系统评价和荟萃分析的质量评估，检查旨在预防牲畜疾病的预防性抗生素使用和管理实践

为了在食用动物生产中实施有效的管理，生产者和兽医必须了解预防性干预措施以减少牲畜疾病。系统评价和荟萃分析 (SR/MA) 提供透明、可复制和经过质量评估的概述。目前，尚不清楚有多少 SR/MA 评估旨在降低畜牧业疾病风险的预防性抗生素使用或管理实践。此外，现有评论的质量是未知的。我们的目的是确定调查这些主题的评论并对其质量进行评估。确定了 38 条相关评论。质量评估基于对系统评价进行严格评估的 AMSTAR 2 框架。捕获的大多数评论的质量被归类为极低（84.2%，n= 32/38），只有一小部分评估的评论不包含关键弱点（7.9%，n= 3/38）。特别是，少数评论报告了先验协议（15.8％，n= 6/38），很少有评论指出关键的审查步骤是重复进行的（研究选择/筛选：26.3%，n= 10/38；数据提取：15.8%，n= 6/38）。开发高质量的综述来总结抗生素减少方法的证据是必不可少的，因此更加遵守合成研究的质量行为指南至关重要。
