Quantitative genetics in the monk parakeet (Myiopsitta monachus) from central Argentina: Estimation of heritability and maternal effects on external morphological traits
(Public Library of Science, 2018-08)
The monk parakeet (Myiopsitta monachus) is a South American species unique among parrots; it builds communal stick nests that allow independence from tree or cliff cavities required by most parrots. As a very successful ...
Body condition score of Nellore beef cows: a heritable measure to improve the selection of reproductive and maternal traits
(2015)
Despite the economic importance of beef cattle production in Brazil, female reproductive performance, which is strongly associated with production efficiency, is not included in the selection index of most breeding programmes ...
Estimates of covariance functions for growth from birth to 630 days of age in Nelore cattle
(2001-12-01)
Weight records of Brazilian Nelore cattle, from birth to 630 d of age, recorded every 3 mo, were analyzed using random regression models. Independent variables were Legendre polynomials of age at recording. The model of ...
Estimates of covariance functions for growth from birth to 630 days of age in Nelore cattle
(2001-12-01)
Weight records of Brazilian Nelore cattle, from birth to 630 d of age, recorded every 3 mo, were analyzed using random regression models. Independent variables were Legendre polynomials of age at recording. The model of ...
Comparison of different models to estimate genetic parameters for carcass traits in a commercial broiler line
(FUNPEC-EDITORA, 2010)
The effect of genetic and non-genetic factors for carcass, breast meat and leg weights, and yields of a commercial broiler line were investigated using the restricted maximum likelihood method, considering four different ...
Genetic parameters for pre-weaning traits in Braunvieh cattle
(FUNPEC-EDITORA, 2009)
The objective of this study was to estimate genetic parameters for pre-weaning traits of Braunvieh cattle raised under tropical conditions in Brazil. The weight and weight gain parameters were birth weight (BW, N = 9955), ...
Estimates of genetic parameters for growth traits in Brahman cattle using random regression and multitrait models
(2015-08-06)
Random regression models (RRM) and multitrait models (MTM) were used to estimate genetic parameters for growth traits in Brazilian Brahman cattle and to compare the estimated breeding values obtained by these 2 methodologies. ...
Genome-wide scan reveals genomic regions and candidate genes underlying direct and maternal effects of preweaning calf mortality in Nellore cattle
(2021-05-01)
We conducted analysis to estimate genetic parameters and to identify genomic regions and candidate genes affecting direct and maternal effects of preweaning calf mortality (PWM) in Nellore cattle. Phenotypic records of ...
Genetic Parameters for Growth Traits of Mediterranean Buffaloes from Brazil, Estimated By Bayesian Inference
(Int Buffalo Information Ctr, 2013-01-01)
Quantitative analysis of growth genetic parameters is not available for many breeds of buffaloes making selection and breeding decisions an empirical process that lacks robustness. The objective of this study was to estimate ...
