title: Tapeworm (Moniezia expansa) in sheep: anthelmintic treatment studies to assess possible pathogenic effects and production loss in young infected animals in the field.
abstract: Niclosamide and cupric acetoarsenite were both effective in removing tapeworm (Moniezia expansa) from unweaned lambs. In four trials there was no significant liveweight gain in niclosamide-drenched, compared with undrenched, animals. Post-mortem examination for tapeworm showed that although one lamb contained 200 ml (bulk volume) of strobila, 50% of 49 infected animals contained 50 ml or less. The greatest number of scoleces in one animal was 41, and 65% of lambs contained four or fewer. M.expansa is not indicated as a cause of diarrhoea in lambs.
