Technical Abstract: Chemotherapy is commonly used to control gastrointestinal nematodes of ruminants. Potential and real problems associated with the continued use of anthelmintic to reduce losses associated with GI nematode infection are the widespread occurrence of drug resistance and the presence of residues on animal derived products. An alternative to reduce / eliminate the dependency on chemical compounds to control GI nematodes is the selection and breeding of genetically resistant stock. It is well known that resistance to infection is variable within host species. The definition of the genes responsible for resistance and identification of markers for selection will allow marker-assisted breeding to enhance resistance to disease. This paper addresses this issue in non-scientific language. It is intended to disseminate information on the progress of these studies to farmers. It contains results of studies conducted at ARS and the initiative etoward implementation of these studies at Embrapa (the Brazilian Agricultural Research Corporation).
