由瘤胃吸虫（Calicophoron daubneyi）引起的胃旁口病的发病率在过去15-20年中在欧洲大大增加。然而，人们对这种疾病对生产的影响知之甚少。本研究首先通过对奶牛和肉牛的屠宰场调查，调查了瘤胃吸虫在英格兰和北爱尔兰（NI）的流行情况，并对瘤胃吸虫对胴体重、构象和脂肪分类的影响进行了评估。其次，本试验旨在评估多布尼氏杆菌感染对奶牛腹泻评分、生产损失和福利的影响，同时评估羟氯胺治疗感染奶牛的影响。NI的瘤胃吸虫流行率高于英格兰，在NI采集的牛尸体中有53.8% （95% CI 51.9 - 55.9%）被感染，而在英格兰的两个屠宰场检测到的瘤胃吸虫患病率分别为16.3% （95% CI 15.8 - 16.8%）和17.9% （95% CI 17.4 - 18.4%）。但感染与未感染牛的冷胴体重差异不显著（P < 0.05）。同样，瘤胃吸虫的存在对胴体形态和脂肪分类也没有影响（P < 0.05）。在第二个试验中，瘤胃吸虫感染和氧氯胺类药物对瘤胃吸虫日增重、腹泻评分和福利评分均无显著影响（P < 0.05）。本次试验的农场管理高标准，动物没有交叉疾病。因此，这些发现表明，在管理良好的农场，生产损失（生长率）不应因亚临床瘤胃吸虫感染而受到损害。
The incidence of paramphistomosis, caused by the rumen fluke, Calicophoron daubneyi, has greatly increased within Europe in the last 15–20 years. However, the production impacts of this disease are poorly understood. This study firstly aimed to investigate the prevalence of rumen fluke in England and Northern Ireland (NI) by conducting an abattoir survey of dairy and beef cattle which also allowed the impact of rumen fluke on carcass weight, conformation and fat classification to be assessed. Secondly, an experiment aimed to assess the impact of C. daubneyi infection on diarrhea score, production loss and welfare in dairy heifers, while also evaluating the impacts of treating infected heifers with oxyclozanide. Rumen fluke prevalence was greater in NI than in England, with 53.8% (95% CI 51.9 - 55.9%) of the NI cattle carcases sampled being infected compared to 16.3% (95% CI 15.8 - 16.8%) and 17.9% (95% CI 17.4 - 18.4%) detected at the two abattoirs in England. However, there was no significant difference (P > 0.05) in the cold carcass weight between infected and non-infected cattle. Similarly, carcass conformation and fat classification were unaffected (P > 0.05) by the presence of rumen fluke. In the second experiment, daily live weight gain (DLWG), diarrhea score and welfare score were also unaffected (P > 0.05) by rumen fluke infection and by oxyclozanide treatment against rumen fluke. The farms in this experiment were managed to a high standard and animals had no intercurrent disease. Therefore, these findings suggest that on well–managed farms, production losses (growth rates) should not be compromised as a result of sub-clinical rumen fluke infection.
