Abstract
This research project aims to: 1) verify the occurrence of GxE interaction for the traits dry matter intake (DMI) and residual feed intake (RAC) in Nelore cattle, by means of reaction norm models evaluating the effect of feed efficiency tests to assess the genetic variation of DMI and CAR in different environmental gradients; 2) evaluate the effect of GxE interaction on SNP markers in dif…

Abstract
The project aims to evaluate the inclusion of inserted SNPs in possible causative QTNs for genomic evaluation of reproductive, carcass and efficiency traits using the ssGBLUP method; to use genome-wide association studies (GWAS) in a population of Nelore cattle using phenotypes related to the probability of early delivery (PP30), stayability (STAY), rib eye area (REA), subcutaneous fat th…

Abstract
Global warming is a major threat to livestock production and under heat stress conditions feed intake and efficiency is altered. In this context, this research project aims to: 1) investigate the occurrence of genotype-by-environment interactions (GxE) for dry matter intake (DMI) and residual feed intake (RFI) in Nellore cattle based on genomic reaction norm models; 2) estimate variance c…
