	abstract = {Thirty-eight adult Merino breeding ewes were drenched with Ivomec  and given a controlled release anthelmintic (benzimidazole) capsule in  August 1992 and December 1993.   Mean FEC in the Untreated group peaked over lambing at 600epg in 1992  and 800epg in 1993. Mean FEC in the Treated group remained below 50epg  during the active period of the capsule. The Treated ewes had a higher  survival rate, were heavier, grew more wool from late July 1993 and weaned  more and heavier lambs in 1993 than the Untreated ewes.   At a mean Merino wool price of 500c/kg greasy, returns from the increased  wool production more than equates with the anthelmintic treatment cost.   Increased returns would be gained from improve ewe survival and increased  lamb production.  },
