The anthelmintic efficacy of albendazole intra-ruminal slow-release capsules (SRC) and albendazole drench against field strains of 5 genera of nematode parasites of sheep, where compared. The SRC reduced the number of L4 and adult Nematodirus by 64.1% and 58.3% and the albendazole drench by 98.1% and 99.1%, respectively. Neither formulation was more than 89.5% effective against either the L4 or adult stage of Teladorsagia. The efficacy of both formulations against the adult stages of Haemonchus, Trichostrongylus and Oesophagostomum ranged from 95.9 to 99.9%.
