通过对1，513头比利时白色蓝色公牛的随机粪便样本进行分析，确定了育肥单位中肝吸虫病的频率，这些公牛年龄在5至7个月之间，体重在200至300 kg之间。12.5%的调查公牛肝吸虫病阳性。这些公牛分布在56.5%的调查育肥单位。此外，在育肥单位内，感染率从0到33.3%不等。为了评估双肌牛片形吸虫病的经济后果以及治疗此类疾病的有益效果，在选定的育肥单位进行了一项试验，试验对象包括30头比利时白色蓝色公牛，体重365 +/- 9 kg，年龄10至12个月。在粪便检查的基础上，将30只动物再分为片形吸虫病阴性（A组; n = 10）和阳性动物（n = 20），后者在本试验的第0天用硝酰苯胺处理（B组; n = 10）或不用硝酰苯胺处理（C组; n = 10），该试验进行了75天。C组日增重（1.661 ± 0.140 kg）显著低于A组（1.975 ± 0.120 kg）。另一方面，B组（1.960 +/- 0.085 kg）和A组记录的日增重之间无显著差异。在75天的时间里，由于吸虫病造成的经济损失估计为C组每头公牛平均2,748比利时法郎。（250字处删节）
The frequency of liver fluke disease in fattening units was determined by the analysis of random faeces samples issued from 1,513 Belgian White Blue bulls aged from 5 to 7 months and weighing from 200 to 300 kg. 12.5% of the investigated bulls were positive for liver fluke disease. These bulls were spread over 56.5% of the investigated fattening units. Furthermore the infestation rate varied from 0 to 33.3% inside the fattening units. In order to assess the economic consequences of bovine fascioliasis in double-muscled cattle and the beneficial effects of a treatment against such a disease, a trial including 30 Belgian White Blue bulls, weighing 365 +/- 9 kg and aged from 10 to 12 months, was conducted in a selected fattening unit. On the basis of faecal examinations, the 30 animals were subdivided in negative (group A; n = 10) and positive animals (n = 20) for fascioliasis, the latter being either treated with nitroxinil (group B; n = 10) or not (group C; n = 10) on day 0 of this trial which was conducted during 75 days. The daily body gains in group C (1.661 +/- 0.140 kg) were significantly lower than those in group A (1.975 +/- 0.120 kg). On the other hand there was no significant difference between the daily body gains registered in group B (1.960 +/- 0.085 kg) and A. The estimated financial loss, due to flukes and accounted on a 75 day-period, averaged 2,748 Belgian Francs per bull in group C.(ABSTRACT TRUNCATED AT 250 WORDS)
