• Abstract

  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…

• Abstract

  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…

• Abstract

  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…

  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

  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…

• Abstract

  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 …

• Abstract

  Genetic connectedness assesses the extent to which estimated breeding values can be fairly compared across management units. Connectedness in genetic evaluation is important if management units differ in their genetic mean. The concept of genetic connectedness in the whole-genome prediction era can be extended to measure the connectedness level between the reference and validation sets. I…

• Abstract

  The large-scale omics data provide great opportunity for biological understanding, however, the challenge in the omics studies consists in combining GWAS findings with molecular data to characterize the associations. This study aimed evaluate the different approaches effects for identification of associated with resistance parasites through meta-analyses study, as well identify integrated…
