[more ▼] In this field trial, the repercussions of 2 administration forms of oxfendazole, namely a single administration of a front-loaded device (group 1; n = 18) and a repeated administration of a 90.6 per cent oral suspension (group 2; n = 18), were compared in first season-grazing double-muscled fattening bulls. The comparison was based on the production performances, the mean worm egg counts and the product- and labour-costs. The daily body gains determined on the whole trial period, i.e. 1.312 +/- 0.055 kg and 1.270 +/- 0.056 kg for groups 1 and 2 respectively, and mean worm egg counts per gram (on days 0 and 130:200.0 +/- 44.3 and 94.4 +/- 27.4 for group 1; 366.7 +/- 98.4 and 100.0 +/- 33.6 for group 2) did not differ significantly between the two groups. However, the total costs were lower with a front-loaded device (1,021 Belgian Francs) than with oral suspension (1,248 Belgian Francs per bull).

[more ▼] 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) [less ▲] Detailed reference viewed: 30 (1 ULg)Application of an enzyme-linked immunosorbent assay (ELISA) involving monoclonal antibody for detection of BLV antibodies in individual or pooled bovine milk samples; Portetelle, Daniel ; in Zentralblatt für Veterinarmedizin.
