The objective is to analyze different strategies for the evaluation of a metapopulation, composed of several breeds such as Nellore, Brahman and Guzerá using the single step genomic BLUP method for growth traits such as weaning weight (W210) and weight adjusted at 15 months of age. (W450). Phenotypic and genotypic information from the Nelore (Nelore Brasil program), Guzerá (Guzerá Brazil …
In relation the nutritional attributes of beef meat quality, the composition of fatty acid is important not only because it affects the meat palatability, but also it can affect the human health. The fatty acids harmful to human health have received attenuating attention in recent years. Some studies, with taurine breed, have shown that there is a genetic variation for the trait fatty aci…
This project aims to evaluate the impact on commercial beef cattle genetic evaluation by the inclusion of genomic information in the evaluation considering different uncertain paternity situations and different genotyping strategies in a real and simulated population. Will be simulated two herds, where one is a commercial beef cattle considering different proportion of genotyped young ani…
The project aims to evaluate the effect of different levels of metabolizable protein supply in the growing on performance, protein metabolism and emission of greenhouse gases (methane emissions (CH4), nitrous oxide (N2O) and volatilization of ammonia (NH3)), as well as effect of preconditioning beef steers rearing on finish of beef cattle in Brazil, in two typical scenarios (feedlot or su…

In this project, the objective is to analyze different strategies for the evaluation of a metapopulation composed of the Nelore, Brahman, and Guzerá breeds, using the single-step genomic method - BLUP for reproductive, growth and carcass quality characteristics, namely: calving probability (3P), weight-adjusted at 15 months of age (P450), loin eye area (AOL) and rump fat thickness (P8), w…
This research project aims to evaluate the effect of using one or many metafounders and missing pedigree in the estimates of (co) variance components, accuracy and bias of prediction for genomic values using the single step BLUP method for traits related to sexual precocity, fertility and longevity in cattle of Nellore breed. Phenotypic and genotypic information from Nellore Brazil breedi…
The aim of this work is to evaluate different strategies for the evaluation of a metapopulation composed of several breeds such as Nellore, Brahman and Guzerá using the BLUP single-step genomic method for growth traits such as weaning weight (P210) and weight adjusted at 15 months of age ( P450). The specific objectives are: a) To evaluate different strategies for obtaining matrix G, impl…
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…
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…
The meat is an important source of amino acids, vitamins, minerals and fatty acids (FA). Health consciousness among consumers has grown the more information and misinformation is publicized about the effects of food components, the demand for healthier products increased, and recently the composition of fatty acid contents in beef cattle. Several studies with taurine breeds indicate the e…

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…
The aim of this project is to evaluate the use of the weighted genomic matrix for the allelic frequencies of the reproductive traits stayability (STAY72) and probability of early calving (PP30) in females, and scrotal circumference (SC365) in males of the Nelore breed using the single-step genomic BLUP (ssGBLUP) method. For the studied traits, an available data set of approximately 505.00…
The objective of this research project is to obtain indirect predictions of genotyped animals of the Brahman, Guzerá and Tabapuã using a multibreed genetic evaluation that also includes the Nelore breed. For this, phenotypic and pedigree information from the breeding programs of the four breeds will be used, from the National Association of Breeders and Researchers (ANCP), Ribeirão Preto,…
The seeking for methodologies capable of increase accuracy of genetic evaluation is constant. However for multi-breed populations few are the studies using ssGBLUP and specific approaches for these populations. The aim of this research project is to evaluate the impact of metafounders use in the genetic parameters estimation, genomicestimation breeding values (GEBV), bias and accuracy of …
