Estimates of genetic parameters, and cluster and principal components analyses of breeding values related to egg production traits in a White Leghorn population
(Poultry Science Assoc Inc, 2011-10-01)
The objectives of this paper were to identify the phenotypic egg-laying patterns in a White Leghorn line mainly selected for egg production, to estimate genetic parameters of traits related to egg production and to evaluate ...

Bayesian Inference of Genetic Parameters for Reproductive and Performance Traits in White Leghorn Hens
(Czech Academy Agricultural Sciences, 2018-01-01)
This study estimated the genetic parameters for reproductive and performance traits and determined which ones can be used as selection criteria for egg production in laying hens using the Bayesian inference. The data of ...
Reduced-rank estimation of genetic parameters for egg production traits and cluster analyses with predicted breeding values
(Taylor & Francis As, 2018-04-03)
The aims of this study were to compare the suitability of the multi-trait (MUT) model to estimate genetic parameters with that of 13 reduced-rank principal component models (PC1 to PC13), and then to explore the additive ...
Life history traits of the snapping shrimp alpheus carlae (Decapoda: Alpheidae) from the south-eastern coast of Brazil
(2021-01-01)
The life history traits of the snapping shrimp Alpheus carlae were investigated. We evaluated the relative growth, morphological sexual maturity, sexual dimorphism, handedness, fecundity, and egg volume. Sampling was ...
Genetic parameters and principal component analysis for egg production from White Leghorn hens
(2013-08-01)
The objectives of this study were to estimate genetic parameters for accumulated egg production over 3-wk periods and for total egg production over 54 wk of egg-laying, and using principal component analysis (PCA), to ...
