Genetic parameters by Bayesian inference for dual purpose Jaffarabadi buffaloes
(Archiv Fur Tierzucht, 2012-01-01)
Knowledge of genetic parameters is essential for improved reproductive management and increased yield. Quantitative analysis of genetic parameters is lacking for many breeds of buffaloes. This article provides the first ...
Genetic variability and genetic gains in progenies of Myracrodruon urundeuva Fr. All. in multi-species system
(Univ Federal Mato Grosso, 2017-01-01)
Improper exploitation of native woods have led to a reduction in natural populations, as was the case of Myracrodruon urundeuva. The objectives of this study were to estimate genetic parameters for silvicultural traits in ...
Bayesian inference in genetic parameter estimation of visual scores in Nellore beef-cattle
(Sociedade Brasileira de Genética, 2009-01-01)
The aim of this study was to estimate the components of variance and genetic parameters for the visual scores which constitute the Morphological Evaluation System (MES), such as body structure (S), precocity (P) and ...
Accumulated productivity and its genetic association with reproductive traits in females Brahman
(Univ Cordoba, 2013-10-01)
Objective. Assessment of genetic parameters for accumulative productivity trait (ACP) and genetic correlations with age at first calving (AFC), between calving interval of first and second parity (BCI1) and longevity (LONG). ...
Parâmetros genéticos para caracteres de crescimento, de produção e tecnológicos da madeira em clones de Eucalyptus spp
(2005-04-01)
This work had to objectives to estimate genetic parameters of growth, yield and technological wood characters in 25 Eucalyptus spp. clones, at 80 months old. The experiment was disposed in the randomized blocks design with ...
Genetic parameters and trends of morphometric traits of GIFT tilapia under selection for weight gain
(Univ Sao Paolo, 2014-07-01)
The main factor considered in breeding programs for fish is growth, which can be assessed in terms of a gain in either weight or body measurements. This study was undertaken to evaluate the morphometric traits of GIFT ...
Genetic parameters for body weight in meat quail
(Oxford Univ Press, 2015-02-01)
The aim of this study was to estimate genetic parameters for BW in meat quail at different ages. A total of 24,382 weight records from 3,652 quail, born between 2009 and 2011, were evaluated. Weekly BW was measured from ...
Estratégias de seleção dentro de progênies em duas populações de myracrodruon urundeuva Fr. All.
(2009-03-01)
Myracrodruon urundeuva Fr. All. is a tree species threatened by human pressure. For this reason, this research aimed at evaluating the behavior of two populations of M. urundeuva in a heterogeneous plantation as a support ...
Genetic study of skin thickness and its association with postweaning growth in Nellore cattle: estimation of the genetic parameters
(Funpec-editora, 2016-01-01)
The objective of the present study was to estimate genetic parameters for skin thickness (ST) and postweaning weight gain (PWG550) in Nellore cattle. Records were obtained from 152,392 Nellore animals born between 2001 and ...
Multibreed genetic evaluation in bovines using simulated data employing a composite population
(2016-10-05)
Genetic evaluations in Brazil are performed within each animal breed; however, with the wide range of extant genetic groups in the country and the increased use of genetic crossing as a form of rapid meat production, more ...
