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...
Background: The impact of extreme changes in weather patterns on the economy and human welfare is one biggest challenges our civilization faces. From anthropogenic contributions to climate change, reducing farming activities a priority since it responsible for up 18% global greenhouse gas emissions. To this end, we tested whether ruminal stool microbiome components could be used as biomarkers methane emission feed efficiency bovine by studying 52 Brazilian Nelore bulls belonging two...
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 objective of this study was to estimate allele frequencies the g.98535683A>G:BTAU7 SNP in CAST gene different genetic groups beef cattle produced Brazil (Nellore and their crosses with Bos taurus), evaluate associations between polymorphism meat traits. Five hundred animals from six were genotyped phenotyped for shear force (SF), myofibrillar fragmentation index (MFI), rib eye area, backfat thickness, total lipids. Alleles A G detected all frequency higher than G. Significant association...
Abstract We conducted a study to identify the fecal metabolite profile and its proximity ruminal metabolism of Nelore steers based on an untargeted metabolomic approach. Twenty-six were feedlot with same diet during 105 d. Feces rumen fluid collected before at slaughter, respectively. The metabolomics analysis indicated 49 common polar metabolites in feces. Acetate, propionate, butyrate most abundant both bio-samples. presented significantly higher concentrations compounds when compared...
The objective of this study was to evaluate the effect backfat thickness (BFT) on meat quality feedlot-finished Nellore bulls (Bos indicu s). Seventy-two animals were feedlot finished for about 100 days. For study, 24 sampled according BFT in longissimus thoracis muscle after slaughter: 12 with up 3.0 mm (class BFT-3) and > 6.0 BFT-6). Chemical (myofibrillar fragmentation index, intramuscular fat content, unsaturated saturated fatty acids) physical (cold carcass weight, rib eye area,...
Abstract Feed cost represents a major economic determinant within cattle production, amounting to an estimated 75% of the total variable costs. Consequently, comprehensive approaches such as optimizing feed utilization through alternative sources, alongside selection feed-efficient animals, are great significance. Here, we investigate effect two diets, traditional corn-grain fed and by-product based, on 14 phenotypes related feed, methane emission production efficiency multi-tissue...
The objective was to investigate gene and protein expression of myosin heavy chain (MyHC) in Nellore cattle slaughtered at different weights (BW) or degrees meat tenderness. Ninety animals with initial BW 370 ± 37 kg, 24 months age, were after 95 days on feed. We evaluated shear force (SF), myofibrillar fragmentation index, ribeye area, backfat thickness, marbling, color, cooking losses. Subsequently, selected divided into four contrasting groups, which light (BW = 504.58 32.36 kg) versus...
Abstract The objectives of this study were twofold: (1) to identify potential differences in the ruminal and fecal metabolite profiles Nelore bulls under different nutritional interventions; (2) metabolites associated with cattle sustainability related-traits. We used interventions feedlot: conventional (Conv; n = 26), by-product (ByPr, 26). Thirty-eight fluid 27 significantly ( P < 0.05) between ByPr Conv groups. Individual dry matter intake (DMI), residual feed (RFI), observed water...
The data showed in this review exposes basic aspects that define organic foods and some factors influence consumption by the population, ie, its production country motivations for of food produced system . This way production, originated early decades 20th century, nowadays involves environmental, social health aspects. Although environment is a more evident aspect than other ones, economic output potential beneficial to are discussed further description about foods. Brazil, has excelled...

Electronic feeders record feeding behaviour as feed events by tracking the animal's in-out visits to feeder. Another way measure is based on meals. However, two approaches provide different outcomes. The objectives of this study were estimate genetic parameters (heritabilities and phenotypic correlations) for event meal traits, their correlations with efficiency traits in Nellore cattle. present analysed six (DMI
