On each farm, 105 sheep were randomly allocated to one of six treatment groups or an untreated control group. Faecal samples were collected on day 0 and days 10\u201314 for worm egg counts and larval differentiation. Single\u2010 and multi\u2010combination anthelmintics, persistent and non\u2010persistent, oral liquid or capsule, pour\u2010on and injectable formulations were tested. Monepantel was not tested.

The 4\u2010way combination product was efficacious (n = 4 farms). Napthalophos resistance was detected on one farm only. Resistance to levamisole (42% of farms), moxidectin injection (50% of farms) and the closantel\/abamectin combination (67% of farms) was identified.
