This paper reviews some important concepts to be considered for the control of gastro-intestinal nematode parasites of sheep and goats, including the epidemiology of this parasitic disease in the Brazilian semiarid, and the occurrence of anti-helminthic resistance in the region. Considering the widespread use of preventive treatments during the dry season, new alternatives for the control of gastrointestinal parasites are recommended, taking into account the parasite integrated control system and the use of methods to allow the presence of susceptible parasites in the refugia. Differences between sheep and goats are discussed, taking into account the higher susceptibility of goats and the necessity to use larger doses in goats than in sheep for most anti-helminthics. |
