Lambs were inoculated with a single dose of Cooperia curticei. Subcutaneous administration of ivermectin at a dosage of 200 micrograms/kg of body weight resulted in 61.1% and 90.4% anthelmintic efficacy, when measured at 7 and 14 days after treatment, respectively. In the treatment groups, parasites that remained were located more distally in the small intestine than those in the lambs in the control groups.
