Preliminary results of epidemiology studies and random examinations to determine the prevalence and seasonal incidence of gastro·inleslinal parasites of sheep and goats in Iran are reported. The value of strategic treatments for control of the gastro·intestinal nematodes. timed according to these results and according to fIock management was assessed in ten experiments. Worm egg counts in treated sheep reduced to and main· tained at low levels throughout lhe experiments. Economic assessment based on incre~sed gains in bodyweights of treated sheep showed that the costs of treatments were recouped with high profits when the el:epcted seasonal rise in worm egg counts occurred in the untreated con trois.  aDisease control  aEpidemiology  aGastrointestinal nematodes  aGoat diseases  aGoats  aParasites  aParasitology  aSheep diseases  aCaprino  aEpidemiologia  aOvino  aParasitologia  aControle  aNematodeo1 aSHAHLAPOOR, A.
