Phenotypic markers to characterize F2 crossbreed goats infected by gastrointestinal nematodes

•We evaluated and characterize goats with different levels of resistance to gastrointestinal parasitic nematodes.•We observed significant differences in phenotypic markers between groups.•Resistant animals presented low EPG counts, high packed cell volume and total plasma protein than susceptible animals.•The number of nematodes in the abomasums and small intestine was higher in susceptible group than in resistant.•The animals identified as resistant had a better response to the gastrointestinal nematodes than animals identified as susceptible.
