欧洲椋鸟（Sturnus vulgaris）是一种入侵鸟类，已知会对植物和动物农业造成损害。新证据表明，椋鸟也可能导致畜牧设施内疾病的维持和传播。确定和减轻导致牲畜疾病的风险途径对于减少人类食品的生产损失和污染是必要的。为了更好地了解椋鸟对牛的疾病传播的影响，我们评估了椋鸟控制的有效性，作为一种工具，以减少肠道沙门氏菌在集中的动物饲养操作。我们匹配了一个大型设施，计划使用DRC-1339（3-氯-4-甲基苯胺盐酸盐，也称为3-氯对甲苯胺盐酸盐，3-氯-4-甲基苯胺）进行操作控制，并与一个不控制鸟类的可比参考设施进行比较。在这两个设施中，我们对牛饲料、牛饮水和牛粪便进行了S。在Starling控制操作之前和之后的肠道。在Starling控制的CAFO内，S。在椋鸟控制操作后，饲料槽中的肠道污染消失，水槽中的肠道污染大幅下降。在参考设施内，S.饲料槽和水槽内的肠道污染大幅增加。没有观察到控制椋鸟可以降低S.在牛群中的肠道。在椋鸟控制行动后，S。肠道沙门氏菌在参考设施上增加，但猪群沙门氏菌的患病率增加。enterica对Starling控制的CAFO的影响保持在预处理水平。在Starling控制的设施中检测到S。在控制操作后，肠道菌从饲料槽中消失，并在水槽中大幅下降。由于牛饲料和水是S. enterica，椋鸟控制显示出作为帮助牲畜生产者管理疾病的工具的希望。然而，我们不认为椋鸟控制应该作为一个独立的工具，以减少S。肠道感染相反，椋鸟控制可以作为集中动物饲养操作的综合疾病管理计划的一部分。
European starlings (Sturnus vulgaris) are an invasive bird species known to cause damage to plant and animal agriculture. New evidence suggests starlings may also contribute to the maintenance and spread of diseases within livestock facilities. Identifying and mitigating the risk pathways that contribute to disease in livestock is necessary to reduce production losses and contamination of human food products. To better understand the impact starlings have on disease transmission to cattle we assessed the efficacy of starling control as a tool to reduce Salmonella enterica within a concentrated animal feeding operation. We matched a large facility, slated for operational control using DRC-1339 (3-chloro-4-methylaniline hydrochloride, also 3-chloro p-toluidine hydrochloride, 3-chloro-4-methylaniline), with a comparable reference facility that was not controlling birds. In both facilities, we sampled cattle feed, cattle water and cattle feces for S. enterica before and after starling control operations. Within the starling-controlled CAFO, detections of S. enterica contamination disappeared from feed bunks and substantially declined within water troughs following starling control operations. Within the reference facility, detections of S. enterica contamination increased substantially within feed bunks and water troughs. Starling control was not observed to reduce prevalence of S. enterica in the cattle herd. Following starling control operations, herd prevalence of S. enterica increased on the reference facility but herd prevalence of S. enterica on the starling-controlled CAFO stayed at pretreatment levels. Within the starling-controlled facility detections of S. enterica disappeared from feed bunks and substantially declined within water troughs following control operations. Since cattle feed and water are obvious routes for the ingestion of S. enterica, starling control shows promise as a tool to help livestock producers manage disease. Yet, we do not believe starling control should be used as a stand alone tool to reduce S. enterica infections. Rather starling control could be used as part of a comprehensive disease management plan for concentrated animal feeding operations.
