Genome-wide association studies for tick resistance in Bos taurus × Bos indicus...
Otto, Pamela I.; Guimarães, Simone E. F.; Verardo, Lucas L.; Azevedo, Ana Luísa S.; Sevillano, Claudia A.; Pires, Maria de Fatima A.Rhipicephalus (Boophilus) microplus is the main cattle ectoparasite in tropical areas. Gir × Holstein crossbred cows are well adapted to different production systems in Brazil. In this context, we performed genome-wide association study (GWAS) and post-GWAS analyses for R. microplus resistance in an experimental Gir × Holstein F2 population. Single nucleotide polymorphisms (SNP) identified in GWAS were used to ...
Genomic selection for boar taint compounds and carcass traits in a commercial p...
Campos, Carolina Filardi de; Lopes, Marcos Soares; Silva, Fabyano Fonseca e; Veroneze, Renata; Knol, Egbert F.; Lopes, Paulo SávioThis study aimed to compare two different Genome-Wide Selection (GWS) methods (Ridge Regression BLUP − RR-BLUP and Bayesian LASSO − BL) to predict the genomic estimated breeding values (GEBV) of four phenotypes, including two boar taint compounds, i.e., the concentrations of androstenone (andro) and skatole (ska), and two carcass traits, i.e., backfat thickness (fat) and loin depth (loin), which were measured i...
Evaluation of Bayesian models for analysis of crude protein requirement for pig...
Silva, Hugo Teixeira; Silva, Fabyano Fonseca e; Ferreira, Aloízio Soares; Veroneze, Renata; Lopes, Paulo SávioWe evaluated the inclusion of information on genetic relationship into the analysis of crude protein requirement in diets for pigs of Brazilian Piau breed, using Bayesian inference. The animals were assigned to treatments in a completely randomized design in factorial scheme 4 × 2 (crude protein levels × sex) with 12 repetitions per treatment. The evaluations were carried out in the initial, growing and finishi...
Censored Bayesian models for genetic evaluation of age at first calving in Braz...
Lázaro, Sirlene Fernandes; Silva, Fabyano Fonseca e; Veroneze, Renata; Lopes, Paulo Sávio; Varona, Luis; Ventura, Henrique Torres; Brito, Lais CostaWe compared different Bayesian models to handle censored data for genetic parameters estimation of age at first calving (AFC) in Brazilian Brahman cattle. Data from females with AFC above 1825 days of age were assumed to have failed to calve and were considered as censored records. Data including information of 53,703 cows were analyzed through the following methods: conventional linear model method (LM), which...
Morphological and molecular differences in corpus luteum of pregnant sows from ...
Costa, Karine A.; Silva, Walmir da; Veroneze, Renata; Montes, José C.; Verardo, Lucas L.; Botelho, Margareth E.; Duarte, Marcio S.; Neves, Mariana M.Comprehending mechanisms controlling corpus luteum (CL) angiogenesis and apoptosis in pregnant sows is essential to understand the physiological role of these processes in CL function, progesterone production and consequently in conceptus development and prenatal mortality. CL from 54 sows from two genetic groups, a commercial line (COM) and the local Piau breed (LPB), were obtained for gene expression (n = 3 C...
Estimation of variance components, genetic parameters and genetic trends for li...
Barbosa, Leandro Teixeira; Lopes, Paulo Sávio; Regazzi, Adair José; Torres, Robledo de Almeida; Santana Júnior, Mário Luiz; Veroneze, RenataRegistros de animais da raça Large White foram usados para estimar componentes de variância, parâmetros e tendências genéticas para a característica número total de leitões nascidos (NLT) como medida do tamanho de leitegada. Na obtenção dos componentes de variância e parâmetros genéticos, foi utilizado o método da Máxima Verossimilhança Restrita, por meio do programa MTDFREML. Foram avaliados dois modelos misto...
Treatment of long-term stored DNA- Comparison between different methods to obta...
Almeida, Maira Pedroso de; Nascimento, Carlos Souza do; Perissé, Iuri Viotti; Duarte, Marcio de Souza; Veroneze, Renata; Guimarães, Simone E. FacioniLong-term stored DNA can be sometimes the only source of genetic material of an organism that does not exist anymore, but a research interest still persists. However, there is a lack of information about useful methods to improve quality from such type of material. In this study, we compared four different protocols using DNA samples collected in 1998. Fresh DNA was also tested aiming to check the differences b...
Linkage disequilibrium patterns and persistence of phase in purebred and crossb...
Veroneze, Renata; Bastiaansen, John WM; Knol, Egbert F; Guimarães, Simone EF; Silva, Fabyano F; Harlizius, Barbara; Lopes, Marcos S; Lopes, Paulo SGenomic selection and genomic wide association studies are widely used methods that aim to exploit the linkage disequilibrium (LD) between markers and quantitative trait loci (QTL). Securing a sufficiently large set of genotypes and phenotypes can be a limiting factor that may be overcome by combining data from multiple breeds or using crossbred information. However, the estimated effect of a marker in one bree...
