The objective of this study was to evaluate the association between oxidative damage proteins (represented by protein carbonylation) and beef tenderness. Three experimental groups were selected shear force (SF): tender (38.2 ± 2.9 N), intermediate (51.9 6.8 tough meat (74.5 7.8 N). Two-dimensional electrophoresis with hydrazide fluorophore derivatization used. structural actin (ACTA1), myosin (MYL1 MYL3), desmin (DES) troponin T (TNNT1 TNNT3), antioxidant (PRDX1, PRDX2 PARK7) heat shock...
The objective of this study was to identify genomic regions that are associated with meat quality traits in the Nellore breed. steers were finished feedlots and slaughtered at a commercial slaughterhouse. This analysis included 1,822 phenotypic records tenderness 1,873 marbling records. After control, 1,630 animals genotyped for tenderness, 1,633 marbling, 369,722 SNPs remained. results reported as proportion variance explained by windows 150 adjacent SNPs. Only largest effects considered....
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...
The objective of this study was to evaluate the accuracy genomic predictions for rib eye area (REA), backfat thickness (BFT), and hot carcass weight (HCW) in Nellore beef cattle from Brazilian commercial herds using different prediction models. Phenotypic data 1756 steers ten Brazil were used. Animals offspring 294 sires 1546 dams, reared on pasture, feedlot finished, slaughtered at approximately 2 years age. All animals genotyped a 777k Illumina Bovine HD SNP chip. Accuracy breeding values...
The objectives of this work were to study the segregation single nucleotide polymorphisms calpain 1, large subunit (CAPN1) and calpastatin (CAST) genes in Nellore (Bos indicus) xBos taurus beef cattle, as well evaluate their effects on meat traits. For this, 300 animals, including 114 Nellore, 67 Angus x 44 Rubia Gallega 41 Canchim, 19 Brangus three-way crosses 15 Braunvieh crosses, genotyped for CAPN4751 [AF_248054.2:g.6545C>T (GenBank accession AF248054.2)] CAST/DdeI [AF_159246.1:g.2959A>G...
Abstract With the availability of high‐density SNP panels and establishment approaches for characterizing homozygosity heterozygosity sites, it is possible to access fine‐scale information regarding genomes, providing more than just comparisons different inbreeding coefficients. This first study that seeks such Mangalarga Marchador (MM) horse breed on a genomic scale. To this end, we aimed assess levels using coefficients, as well characterize homozygous heterozygous runs in population....
Carcass traits measured after slaughter are economically relevant in beef cattle. In general, the house payment system is based on HCW. Ribeye area (REA) associated with amount of meat carcass, and a minimum backfat thickness (BFT) necessary to protect carcass during cooling. The aim this study was identify potential genomic regions harboring candidate genes affecting those Nellore data set used present consisted 1,756 males phenotype records. A subset 1,604 animals had both genotypic...
The objective of this study was to determine whether visual scores used as selection criteria in Nellore breeding programs are effective indicators carcass traits measured after slaughter. Additionally, evaluated the effect different structures relationship matrix ( and ) on estimation genetic parameters prediction accuracy values. There were 13,524 animals for conformation (CS), finishing precocity (FP), muscling (MS) 1,753, 1,747, 1,564 LM area (LMA), backfat thickness (BF), HCW,...
Abstract Transcript data obtained by RNA-Seq were used to identify differentially expressed alternatively spliced genes in ribeye muscle tissue between Nelore cattle that differed their area (REA) or intramuscular fat content (IF). A total of 166 transcripts from 125 significantly the highest and lowest REA groups (p ≤ 0.05). For animals selected on IF content, 269 219 animals. Cassette exons alternative 3′ splice sites most frequently found for content. both traits, some belonged myosin...
The objective of this study was to investigate the effects bovine GH1, CAPN1 and CAST gene polymorphisms on carcass meat traits in Nellore x Bos taurus beef cattle. Three hundred animals were genotyped for GH1/MspI (TC/G intron 3), CAPN316 (AF_252504.2:g.5709C>G) CAST/RsaI (AY_008267.1:g282C>G) phenotyped rib eye area, backfat thickness, intramuscular fat, shear force (SF), myofibrillar fragmentation index (MFI). No significant associations observed between phenotypes, although relation...
Leptin, thyroglobulin and diacylglycerol O-acyltransferase play important roles in fat metabolism. Fat deposition has an influence on meat quality consumers' choice. The aim of this study was to determine allele genotype frequencies polymorphisms the bovine genes, which encode leptin (LEP), (TG) (DGAT1). A further objective establish effects these characteristics. We genotyped 147 animals belonging Nelore (Bos indicus), Canchim (5/8 Bos taurus + 3/8 Rubia Gallega X (1/2 1/2 Brangus Three-way...
The aim of this study was to estimate genetic and phenotypic associations growth traits with carcass meat in Nellore cattle.Data from male female animals were used for weaning weight (WW; N = 241,416), yearling (YW, 126,596), gain (GWY, 78,687), hip height (YHH, 90,720), respectively; 877 hot (HCW) 884 longissimus muscle area (LMA), backfat thickness (BT), marbling score (MS), shear force (SF).The variance components estimated by the restricted maximum likelihood method using three-trait...
The objective of this study was to evaluate the association expression CAPN1, CAPN2, CAST, HSP90AA1, DNAJA1 and HSPB1 genes with meat tenderness in Nellore cattle. Three experimental groups were selected by shear force (SF): moderately tender (SF=34.3±5.8N), tough (SF=56.8±7.8N), very (SF=80.4±15N). Gene evaluated real-time PCR. Expression CAST CAST1 did not differ between groups. CAST2 up-regulated (P<0.05) Down-regulation observed group. present results suggest that cattle does directly...
Subcutaneous fat deposition measured as backfat thickness (BFT) increases protection for the bovine carcass during cooling, conferring to BFT an important characteristic meat industry. To study influence of on quality traits Nellore bulls (Bos indicus), data from 1652 animals aged 20–24 months in feedlot finishing were used. The principal component analysis (PCA) was performed characterise variables longissimus thoracis muscle. Measurements comprised rib eye area, BFT, marbling, shear force,...
The aim of this study was to use transcriptome RNA-Seq data from longissimus thoracis muscle uncastrated Nelore males identify hub genes based on co-expression network obtained differentially expressed (DEGs) associated with intramuscular fat content.A total 30 transcriptomics datasets (RNA-Seq) were selected the phenotypic value divergent content: 15 highest content (HIF) and lowest (LIF). aligned a reference genome 65 identified, including 21 upregulated 44 downregulated in HIF animals....
