Background. The cattle tick is a parasite that adversely affects livestock performance in tropical areas. Although countries such as Australia and Brazil have developed genetic evaluations for tick resistance, these evaluations have not considered genotype by environment (G*E) interactions. Genetic gains could be adversely affected, since breedstock comparisons are environmentally dependent on the presence of G*E interactions, particularly if residual variability is also heterogeneous across environments. The objective of this study was to infer upon the existence of G*E interactions for tick resistance of cattle based on various models with different assumptions of genetic and residual variability.  © Mota et al. 2016  aBRAFORD  aGANADO DE CARNE  aHEREFORD1 aTEMPELMAN, R.J.1 aLOPEZ, P.S.1 aAGUILAR, I.1 aSILVA, F.S.1 aCARDOSO, F.S.  tGenetics Selection Evolution, 2016gv. 48, no. 3.
