This study was designed to estimate genetic parameters for the following traits of Brahman cattle in Brazil: age at first calving (AFC), interval (CI), rebreeding (REB), and stayability (STAY). For REB, value 1 assigned heifers that rebred calved after 0 failed rebreed calving. Likewise, STAY, cows least 3 times by time they reach 6 yr age; otherwise, assigned. A bivariate analysis used covariances components using linear animal model CI AFC threshold REB STAY. The mean h2 were 0.10, 0.02,...
To examine genetic association between rheumatoid arthritis (RA) and known polymorphisms in core genes of the nuclear factor (NF)kappaB pathway, major intracellular pathway RA pathogenesis.Discovery replication sample sets Spanish patients with controls were studied. A total 181 single nucleotide (SNPs) uniformly spaced along genomic sequences 17 NFkappaB (REL, RELA, RELB, NFKB1, NFKB2, NFKBIA, NFKBIB, NFKBIE, IKBKA, IKBKB, IKBKE, IKBKAP, KBRAS1, KBRAS2, MAP3K1, MAP3K14, TAX1BP1) studied by...
Abstract Visual scores are assigned with no basis on an absolute reference. In this case, evaluation references different for each group, depending only the structure of group. Thus, factors that change groups, such as group size, can affect visual score assignment, well estimation genetic parameters and prediction breeding values, respectively. The objective study to determine consequences assigning based a relative reference values considering sizes. A simulation was conducted 6 scenarios...
Resumo Escores visuais são atribuídos sem considerar uma referência absoluta. Nesse caso, as referências de avaliação diferentes para cada grupo avaliado, dependendo apenas da estrutura do grupo. Assim, fatores que alteram a dos grupos avaliação, como o tamanho grupo, podem afetar atribuição escore visual, bem estimação e predição parâmetros genéticos valores aditivos, respectivamente. O objetivo deste estudo é determinar consequências escores com base em relativa na estimativa considerando...
Mesenteric torsion (MT) is a condition that affects several animal species and can lead to the animals' death. However, little known about its etiology. Therefore, this study aimed identify genomic regions candidate genes associated with MT. Phenotypic genotypic data from 405 pigs, including MT records genealogy were used. In model, contemporary group (sex, year, week of weaning) was considered fixed effect, linear effect weaning weight as covariate, while direct additive genetic random....
The aim of this study was to estimate genetic parameters for BW in meat quail at different ages. A total 24,382 weight records from 3,652 quail, born between 2009 and 2011, were evaluated. Weekly measured hatch until 42 d age. estimated by the restricted maximum likelihood method using a multivariate animal model. Heritability ranged 0.03 0.23. Genetic correlations mainly high positive. Selection 28 age yielded good indirect progress
Genome-wide association studies (GWAS) are utilized in cattle to identify regions or genetic variants associated with phenotypes of interest, and thus, design strategies that allow for the increase frequency favorable alleles. Visual scores important traits production Brazil because they as selection criteria, helping choose more harmonious animals. Despite its importance, there still no on genome these traits. This study aimed conformation, precocity muscling, based a visual score measured...
Abstract: The objective of this work was to evaluate the genetic diversity Brahman cattle in Brazil with pedigree analysis. Genealogical records a subpopulation were used considering all information (Pt) and divided into two periods (P1, from 1994 2004; P2, 2005 2012) or according raising system (Ppt, animals on pasture; Pst, stable). Estimates obtained for average inbreeding coefficients, generation intervals (GI), number equivalent known (CGE), founders (Nf), effective (fe), ancestors...
The objective of this study was to evaluate the association visual scores body structure, precocity and muscularity with production (body weight at 18 months average daily gain) reproductive (scrotal circumference) traits in Brahman cattle order determine possible use these as selection criteria improve carcass quality. Covariance components were estimated by restricted maximum likelihood method using an animal model that included contemporary group fixed effect. A total 1,116 observations...
Random regression models (RRM) and multitrait (MTM) were used to estimate genetic parameters for growth traits in Brazilian Brahman cattle compare the estimated breeding values obtained by these 2 methodologies. For RRM, 78,641 weight records taken between 60 550 d of age from 16,204 analyzed, MTM, analysis consisted 17,385 at same ages 12,925 cattle. All included fixed effects contemporary group additive genetic, maternal animal permanent environmental quadratic effect calving (AAC) as...
Hernia is one of the most common defects in pigs. The prevalent are scrotal (SH), inguinal (IH) and umbilical (UH) hernias. We compared ring transcriptome normal SH-affected pigs with UH-affected to discover genes pathways involved development both types hernia. A total 13,307 transcripts was expressed 13,302 tissues 94.91% them present tissues. From those, 35 were differentially groups, participating 108 biological processes. 67 polymorphisms identified 76 tissue, which 11 14 novel,...
O objetivo do trabalho foi estimar os parâmetros genéticos das características de crescimento da raça Suffolk, a fim fornecer subsídio para definição estratégias seleção programas melhoramento genético. Os dados analisados, coletados entre anos 2007 2009, são referentes ovinos Suffolk oriundos uma propriedade localizada no Estado São Paulo, Brasil, participante programa genético Ovigol, conduzido pela empresa Aries Reprodução e Melhoramento Genético Ovino Ltda. em parceria com AbacusBio...
Abstract: The objective of this work was to evaluate the effects genomic information on genetic evaluation hip height in Brahman cattle using different matrices built from and pedigree data. Hip measurements 1,695 animals, genotyped with high-density SNP chip or imputed 50 K chip, were used. numerator relationship matrix (NRM) compared H matrix, which incorporated NRM (G) simultaneously. genotypes used estimate three versions G: observed allele frequency (HGOF), average minor (HGMF), 0.5 for...
The objective of this study was to evaluate the impact farrowing and mortality rates on inbreeding levels genetic gain through data simulation. Data came from two real populations A B, composed Pietrain Landrace breed pigs, respectively. To generate simulated populations, a Fortran-language simulator developed using (co)variances breeding values productive reproductive information obtained as well restrictions mating animals selected per generation. Two files were created. first contained...
Abstract The aim of this study was to estimate the influence heterosis and breed percentage on birth weight (BW) weaning (WW) in beef cows a tropical environment. Data from 900 calves 2,843 individuals pedigree, multibreed herd Panama Agricultural Innovation Institute (IDIAP) Gualaca, were used. comprised following genetic groups according their percentage: adapted Brahman (BR), Nellore (Ne), Un define Bos indicus (BI), Guaymi Creole (CR), Senepol (SP) Romosinuano (RS); taurus (BT),...
