Helminthiasis due to roundworms is a major problem and constraint to the intensive and large scale rearing of sheep in Malaysia. A trial using the anthelmintic, invermectin, was undertaken to determine its efficacy against nematodes of sheep and to establish a treatment interval for prophylaxis in a sheep farm near Ipoh, Perak. The efficacy was 100% for adult Haemonchus contortus, adult and immature Trichostrongylus colubriformis, and adult Oesophagostomum columbianum. Treatment at monthly intervals resulted in very few strongyle eggs ( mean 22 epg), low egg counts in the two-month-treatment-interval group (mean 111 epg) and a mean of 407 epg in the control (untreated) group. The sheep showed no adverse effects due to invermectin administration.
