Since 2018, when a process hygiene criterion for in broilers at the slaughterhouse was implemented across Europe, efforts to reduce at farm level have increased. Despite numerous studies aiming to reduce colonization in broilers, no efficient control strategy has been identified so far. The present work assessed first the efficacy of a commercial litter treatment to reduce colonization in broilers during two in-vivo trials and second, its impact on cecal microbiota. The treatment does not affect broiler growth and no effect on counts was observed during the in-vivo trials. Nevertheless, cecal microbiota were affected by the treatment. Alpha and beta diversity were significantly different for the control and litter-treated groups on day 35. In addition, several taxa were identified as significantly associated with the different experimental groups. Further work is needed to find a suitable control measure combining different strategies in order to reduce .
自2018年欧洲各地实施屠宰场肉鸡过程卫生标准以来，农场层面减少（相关细菌，原文未明确）的努力有所增加。尽管有许多旨在减少肉鸡（相关细菌）定植的研究，但迄今为止尚未确定有效的控制策略。本研究首先在两项体内试验中评估了一种商业垫料处理方法减少肉鸡（相关细菌）定植的效果，其次评估了其对盲肠微生物群的影响。该处理方法不影响肉鸡生长，在体内试验期间未观察到对（相关细菌）数量的影响。然而，盲肠微生物群受到了该处理方法的影响。在第35天，对照组和经垫料处理组的α和β多样性存在显著差异。此外，还确定了几个与不同实验组显著相关的分类群。需要进一步开展工作，以找到一种结合不同策略的合适控制措施，以减少（相关细菌）。
