[Effectiveness of Nilzan and Dovenix in the treatment of fascioliasis in cattle and sheep].

The authors tested the effectivity of the foreign preparations Nilzan (tetramisole ++ oxyclozanide) and Dovenix (nitroxynil) in the treatment of cattle and sheep naturally invaded by Fasciola hepatica. The effectiveness of the two preparations was evaluated on the basis of the results of coprological examination in the test and control animals prior to treatment and in two intervals after treatment. In slightly invaded cattle (the average egg number in 3 g of faeces in 28 test cows was 1.46 per animal) the last examination (4 weeks after treatment) showed 100-per-cent extenseffectiveness and intenseffectiveness of both preparations. When the test was finished in sheep (average number of eggs in 3 g of faeces in 45 test ewes--5.40 per animal) six weeks after treatment, the EE of Nilzan was 86.7% and IE 97.4%; in Dovenix EE was 93.4% and IE 99.0%. Both preparations were accepted well, without any side-effects or unfavourable phenomena related to their application.
