Female fertility in a Guzerat dairy subpopulation: heterogeneity of variance components for calving intervals. Author(s): PANETTO, J. C. C.; VAL, J. E.; MARCONDES, C. R.; PEIXOTO, M. G. C. D.; VERNEQUE, R. da S.; FERRAZ, J. B. S.; GOLDEN, B. L. 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... ...

Modeling the variance-covariance matrix of genetic and residual effects in a Panicum maximum genome wide selection experiment. Author(s): LARA, L. A. DE C.; SANTOS, M. F.; JANK, L.; CHIARI, L.; GARCIA, A. A. F. 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. Author(s): THOLON, P.; QUEIROZ, S. A. 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
