Isotonic regression analysis of Guzerá cattle growth curves
Rodrigues, Adriano; Chaves, Lucas Monteiro; Silva, Fabyano Fonseca; Garcia, Idalmo Pereira; Duarte, Darlene Ana Souza; Ventura, Henrique TorresObjetivou-se aplicar a transformação de dados via regressão isotônica em estudos de crescimento de animais da raça Guzerá cujos dados apresentam distúrbios caracterizados por decréscimos de pesos em determinadas faixas de idades. Foram tomadas observações de peso-idade de machos da raça Guzerá recém-desmamados obedecendo à metodologia das provas de ganho de peso (PGP) definidas pela Associação Brasileira dos Cr...
Differentially transcribed genes in skeletal muscle of lambs
Lôbo, Ana Maria Bezerra Oliveira; Guimarães, Simone Eliza Faccioni; Paiva, Samuel Rezende; Cardoso, Fernando Flores; Silva, Fabyano FonsecaThe objective of this study was to compare gene transcription profiles in Longissimus dorsi muscle of the following four hair sheep genetic groups, Morada Nova (MO), Brazilian Somali (SO), Santa Inˆes (SI) and 1⁄2Dorper  1⁄2Morada Nova (F1). These groups all display different postnatal muscle growth. The transcriptomes of the skeletal muscle of the lambs (at 200 days of age) were profiled by using oligonucleot...
Regressão aleatória Bayesiana para avaliação genética da resistência ao mal das...
Sandoval, Victor Javier Cevallos; Silva, Fabyano Fonseca; Resende, Marcos Deon Vilela de; Macedo, Leandro Roberto de; Cecon, Paulo RobertoO mal das folhas causado pelo fungo Microcyclus ulei é a doença mais séria dos seringais da América Latina. Com o objetivo de identificar clones de seringueira mais resistentes em diferentes ambientes ao longo do tempo, compararam-se diferentes modelos de regressão aleatória (MRA) ajustados via abordagem Bayesiana. Oito clones foram testados em campos clonais no delineamento em blocos completos casualizados com...
Bayesian model combining linkage and linkage disequilibrium analysis for low de...
Silva, Fabyano Fonseca; Jerez, Elcer Albenis Zamora; Resende, Marcos Deon Vilela de; Viana, José Marcelo Soriano; Azevedo, Camila FerreiraWe combined linkage (LA) and linkage disequilibrium (LDA) analyses (emerging the term ‘LALDA’) for genomic selection (GS) purposes. The models were fitted to a simulated dataset and to a real data of feed conversion ratio in pigs. Firstly, the significant QTLs (quantitative trait locus) were identified through LA-based mixed models considering the QTL-genotypes as random effects by means of genotypic identity b...
Effect of influent aeration on removal of organic matter from coffee processing...
Rossmann, Maike; Matos, Antonio Teixeira; Abreu, Edgar Carneiro; Silva, Fabyano Fonseca; Borges, Alisson Carrarohe aim of the present study was to evaluate the influence of aeration and vegetation on the removal of organic matter in coffee processing wastewater (CPW) treated in 4 constructed wetlands (CWs), characterized as follows: (i) ryegrass (Lolium multiflorum) cultivated system operating with an aerated influent; (ii) non-cultivated system operating with an aerated influent, (iii) ryegrass cultivated system operati...
Zero-inflated Poisson regression models for QTL mapping applied to tick-resista...
Silva, Fabyano Fonseca; Tunin, Karen P.; Rosa, Guilherme J.M.; Silva, Marcos V.B. da; Azevedo, Ana Luisa Souza; Verneque, Rui da SilvaNowadays, an important and interesting alternative in the control of tick-infestation in cattle is to select resistant animals, and identify the respective quantitative trait loci (QTLs) and DNA markers, for posterior use in breeding programs. The number of ticks/animal is characterized as a discrete-counting trait, which could potentially follow Poisson distribution. However, in the case of an excess of zeros,...
Regional heritability mapping and genome-wide association identify loci for com...
Resende, Rafael Tassinari; Resende, Marcos Deon Vilela; Silva, Fabyano Fonseca; Azevedo, Camila Ferreira; Takahashi, Elizabete KeikoAlthough genome-wide association studies (GWAS) have provided valuable insights into the decoding of the relationships between sequence variation and complex phenotypes, they have explained little heritability. Regional heritability mapping (RHM) provides heritability estimates for genomic segments containing both common and rare allelic effects that individually contribute too little variance to be detected by...

Genomic simulation for the study of data transformation efficiency in the genet...
Carneiro, Antonio Policarpo Souza; Carneiro, Paulo Luiz Souza; Euclydes, Ricardo Frederico; Martins Filho, Sebastião; Silva, Fabyano FonsecaEfficiency of data transformation strategies is evaluated to correct heterogeneity among cattle in the genetic evaluation of bulls, cows and progenies. Four data structures of bovine weaning weights were simulated: herds with and without heterogeneity for means and variances, and herds with and without genetic connectedness. In the genetic evaluations, data were used in the original scale and transformed (Logar...
