This research evaluated a multivariate approach as an alternative tool for the purpose of selection regarding expected progeny differences (EPDs). Data were fitted using multi-trait model and consisted growth traits (birth weight weights at 120, 210, 365 450 days age) carcass (longissimus muscle area (LMA), back-fat thickness (BF), rump fat (RF)), registered over 21 years in extensive breeding systems Polled Nellore cattle Brazil. Multivariate analyses performed standardized (zero mean unit...
Abstract The goal of this study was to compare the predictive performance artificial neural networks (ANNs) with Bayesian ridge regression, Lasso, Bayes A, B and Cπ in estimating genomic breeding values for meat tenderness Nellore cattle. animals were genotyped Illumina Bovine HD Bead Chip (HD, 777K from 90 samples) GeneSeek Genomic Profiler (GGP Indicus HD, 77K 485 samples). quality control genotypes applied on each comprised removal SNPs located non‐autosomal chromosomes, minor allele...
Several methods have been used for genome-enabled prediction (or genomic selection) of complex traits, example, multiple regression models describing a target trait with linear function set genetic markers. Genomic selection studies focused mostly on single-trait analyses. However, most profitability traits are genetically correlated, and an increase in accuracy breeding values correlated is expected when using multiple-trait models. Thus, this study was carried out to assess the carcass...
There is a growing interest to improve feed efficiency (FE) traits in cattle. The genomic selection was proposed these since they are difficult and expensive measure. Up date, there scarce studies about the implementation of for FE indicine cattle under different scenarios pseudo-phenotypes, models, validation strategies on commercial large scale. Thus, aim evaluate feasibility Nelore applying models pseudo-phenotypes strategies. Phenotypic genotypic information from 4 329 3 467 animals were...
This paper presents the study of relationship between soil apparent electrical resistivity ρ <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">a</sub> and i) moisture content, ii) clay content iii) compaction, for use as a mapping tool spatial variability. It was held measures ρa in different types, varying gradually while maintaining constant then compaction relating it to humidity. For variability, chosen an area that would allow change order...
This paper presents the study of relationship between electrical properties and physical characteristics soil. Measures apparent resistivity soil were made for different types soil, varying moisture content gradually while maintaining a constant compaction, then compaction relating it to humidity. Development correlation surface is proposed in order identify granulometry from measurements. For spatial variability, two areas chosen allow change verify measurement capacity as methodology...
ABSTRACT: This research evaluated different rice genotypes regarding physicochemical and instrumental parameters of grain quality associated the data with sensory analysis to support creation rules for classification culinary (texture), based on isolated or combined parameters. The combination amylose content gelatinization temperature was able predict quality. According sensorial panel, stickiness segregate very low waxy other ones. Regarding pasting properties, that presented high final...
Growth and carcass traits are essential selection criteria for beef cattle breeding programs. However, it is necessary to combine these measurements with body composition meet the demand of consumer market. This study aimed estimate genetic parameters visual scores, growth (pre post-weaning weights), (rib eye area (REA), back rump fat thickness) in Nellore using Bayesian inference. Data from 12,060 animals belonging HoRa Hofig Ramos herd were used. Morphological evaluated by MERCOS...
Resumo A utilização de características morfológicas bovinos, pelo uso escores visuais como critério seleção indireta tem vantagem a avaliação em animais jovens quanto ao potencial desempenho produtivo e reprodutivo, antecipando tomada decisão comparação medidas tomadas forma tardia, perímetro escrotal aos 450 dias (PE450) stayability (STAY). Objetivou-se estimar os parâmetros genéticos para associação dessas com reprodutivas, 365 (PE365) idade, PE450, STAY, probabilidade parto precoce (3P)...

The whitefly is a very difficult plague to combat. It operates in various types of culture and each year has led major losses farmers across the nation. To combat whitefly, pesticides or agrochemicals increasingly powerful are being used. One consequence contamination soils, rivers also risks consumer health, particularly crops tomatoes, cucumbers, strawberries, beans many others. way find ways these pests when attack at beginning. For this purpose, an information system will be built order...
