The efficacy of intraruminal albendazole (ABZ) capsules (Proftril-Captec) and the effect of treatment on productivity parameters were studied in two experiments totally on 466 ewes naturally infected with gastrointestinal nematodes and trematodes D. dendriticum. Ovoscopical tests revealed that treated animals remained negative during 10 - 12 weeks after the administration of capsules and that pasture contamination with helminths was significantly reduced. Necropsy revealed 96.9 - 99.2% efficacy against nematodes Nematodirus spp., Oesophagostomum spp., Cooperia spp., Trichostrongylus spp. and Trichuris ovis. Priority finding is the, efficacy of ABZ capsules against trematodes D. dendriticum which was in the first experiment 88.5% and in the second experiment 91.8%. During the 6-month pasture season treated ewes produced on average 2.56 kg cheese and 0.6 kg wool per ewe more than untreated controls
