Female fertility in a Guzerat dairy subpopulation: heterogeneity of variance components for calving intervals. The objectives of the present study were to determine if variance components of calving intervals varied with age at calving and if considering calving intervals as a longitudinal trait would be a use... ...

Heterogeneity of variance and genetic parameters for milk production in cattle, using Bayesian inference. Author(s): PANETTO, J. C. do C.; SILVA, M. V. G. B.; MARQUES, J. R. F. The goal of this study was to verify the effect of heterogeneity of variance (HV) on milk production in up to 305 days of lactation (L305) of daughters of Girolando, Gir and Holstein sires, as well as... ... Repository: BDPA Publication year: 2023
Fitting of fixed regression curves with different residual variance structures for Nellore cattle growth modeling. Author(s): AZEVEDO, D. M. M. R. Different polynomial functions were tested for mean trajectory modeling with different residual variance structures. A total of 15,148 weight records of 3,115 Nellore Mocho cattle with ages between 1... ... Repository: BDPA Publication year: 2020
Estimates for genetic variance components in reciprocal recurrent selection in populations derived from maize single-cross hybrids. Author(s): ABREU, G. B.; GUEDES, F. L. This study was carried out to obtain the estimates of genetic variance and covariance components related to intra- and interpopulation in the original populations (C0) and in the third cycle (C3) of r... ...

Modeling the variance-covariance matrix of genetic and residual effects in a Panicum maximum genome wide selection experiment. Author(s): SANTOS, M. F.; JANK, L.; CHIARI, L. Panicum maximum stands out among the tropical forage species due to its high biomass yield and excellent nutritional quality, providing high animal performance. The improvement of sexual plant populat... ... Repository: BDPA Publication year: 2016
Estimation of (co)variance components and genetic parameters for weights of red-winged tinamou using random regression models. The objective of this work was to determine genetic parameters for body weight of tinamou in captivity. It was used random regression models in analyses of data by considering the direct additive gene... ... Repository: BDPA Publication year: 2011
Maturation and maceration effects on tropical red wines assessed by chromatography and analysis of variance: principal component analysis. Effects of grape maturity, maceration length during winemaking and interaction of both of them on physicochemical parameters, phenolic and volatile composition were investigated in tropical Syrah wine... ...

Study of heterogeneity of variance and genetic parameters for milk production of Gyr cattle. Author(s): SILVA, M. V. G. B.; PANETTO, J. C. do C. Repository: BDPA Publication year: 2018
Genome-wide mapping of loci explaining variance in scrotal circumference in Nellore Cattle. Author(s): SILVA, M. V. G. B. The reproductive performance of bulls has a high impact on the beef cattle industry. Scrotal circumference (SC) is the most recorded reproductive trait in beef herds, and is used as a major selection... ... Repository: BDPA Publication year: 2014
Heterogeneity of variance and genetic parameters for milk production up to 305 days in girolando cattle by bayesian inference. Author(s): SILVA, M. V. G. B.; PANETTO, J. C. do C. Repository: BDPA Publication year: 2018
