ABSTRACT For developing beef cattle breeding programmes, it is essential to understand the genetic basis of economically relevant traits, such as carcass, meat quality and female sexual precocity. However, direct selection most these traits a challenge for producers because high cost measurement difficulty. Genetic correlation estimates between carcass obtained after slaughter precocity indicator in Nellore are limited literature. Thus, this study aimed estimate parameters longissimus muscle...
Understanding the biological factors that influence carcass and meat quality traits in Nellore cattle requires a clear interpretation of molecular complexity its variations at different levels expression. Hence, this study aimed to elucidate control by integrating genome-wide association (GWAS), transcriptomic, proteomic data, focusing on identifying key genes pathways. GWAS analysis was performed using weighted single-step GBLUP with two iterations. RNA-Seq analyses were 24 muscle samples...
Abstract This study aimed to identify differentially expressed (DE) long non-coding RNAs (lncRNAs) in muscle tissue of Nellore cattle clustered by their fatty acid profile. Longissimus thoracis samples from 48 young bulls were used quantify (FA) (myristic, palmitic, stearic, oleic, linoleic, conjugated linoleic (CLA), α-linolenic and the groups saturated acids (SFA), monounsaturated (MUFA), polyunsaturated (PUFA), ω3, ω6, PUFA/SFA ratio ω6/ω3) generate RNA-Sequencing data for transcriptomic...
Despite several studies on genetic markers and differentially expressed genes related to ribeye area (REA) tenderness traits in beef cattle, there is divergence the results regarding associated with these traits. Thirteen or exhibiting biological functions that might influence such phenotypes were included this study. A total of five for REA (IGF-1, IGF-2, MSTN, NEDD4, UBE4A) eight meat (CAPN1, CAPN2, CAST, HSPB1, DNAJA1, FABP4, SCD, PRKAG3) selected from previous cattle. Genes their...
The identification and selection of genetically superior animals for residual feed intake (RFI) could enhance productivity minimize environmental impacts. aim this study was to use RNA-seq data identify the differentially expressed genes (DEGs), known non-coding RNAs (ncRNAs), specific biomarkers enriched biological processes associated with RFI liver in Nellore cattle two genetic groups. In group 1 (G1), 24 extreme (12 low (LRFI) versus 12 high (HRFI)) were selected from a population 60...
