It is necessary to adopt technological solutions and health recommendations to make production more efficient because the existing herds are suffering from infections caused by gastrointestinal nematodes (GIN), particularly Haemonchus contortus.  aBrazil  agastrointestinal nematodes  aCurrent challenges  aVitro tests1 aMOLENTO, M.
