Abstract

In the early 1970s, when beef cattle numbers increased in the South West, worms came to be recognised as the cause of one of the most significant health problems affecting production. The disease ostertagiosis, caused by the brown stomach worm, Ostertagia ostertagi, started to occur regularly, but the anthelmintics available at the time were limited in their efficiency against the parasite. Because little was known of the epidemiology of ostertagiosis under local conditions, recommendations for control were based on observations made elsewhere in Australia and overseas. These were unsuited to local conditions and did not provide adequate control.
