Description: This work aimed to evaluate hematological parameters and phagocytic neutrophil functions of naturally selected Curraleiro Pé Duro cattle breed (Bos taurus) and crossbreed cattle (Bos taurus X Bos indicus). Two groups of adult cows: Natural= Curraleiro Pé Duro cattle breed (n=10) and Selected = ¾ Nelore X Simental crossbreed animals (n=10) were evaluated. Blood was sampled to make hemogram, in vitro evaluation of neutrophil phagocytosis and basal Nitroblue Tetrazolium - NBT reduction (without any stimulus). The results showed no difference in hematological parameters between these groups. Natural group had greater phagocytic index of neutrophils through pathogen-associated molecular patterns receptors (PAMPs) while in Selected group this same index was greater using opsonin receptors. The reduction of NBT was lower for Natural group than Selected group. In conclusion, we suggest that both animal groups showed differences in neutrophil phagocytic functions in relation to pathway activation and Curraleiro Pé Duro cattle breed produced more oxygen radicals (superoxide, O2-) than the other tested group.
