Genetic parameters and mapping quantitative trait loci associated with tibia traits in broilers. Abstract: Selection among broilers for performance traits is resulting in locomotion problems and bone disorders, once skeletal structure is not strong enough to support body weight in broilers with h... ...

Genetic parameters for growth traits in Senepol cattle. To provide information that can contribute to the genetic evaluation and selection of Senepol cattle, genetic parameters were estimated for growth traits. Birth weight (BW), weaning weight (WW) and po... ... Repository: BDPA Publication year: 2018
Estimation of genetic parameters of turiaçu pineapple clones and genetic correlation between traits. This study aimed to estimate genetic parameters of Turiaçu pineapple clones using mixed models; and estimate genetic correlation coefficient between traits, to provide important information to breedin... ...

Genetic control of traits related to maturity in cowpea. The aim of this study was to investigate genetic control of the traits number of days to flowering (NDF) and number of days to maturity (NDM) in a cowpea cross. Genetic parameters were estimated in se... ... Repository: BDPA Publication year: 2020
Maximizing multi-trait gain and diversity with genetic algorithms. Genetic gain followed by loss of diversity is not ideal in breeding programs for several species, and most studies face this problem for single traits. Thus, we propose a selection method based on Gen... ... Repository: BDPA Publication year: 2023
Genetic parameters for type traits in Holstein cows in Brazil. Data from 26,558 Holstein cows in 802 herds were used to estimate genetic, residual and phenotypic parameters for 22 type traits. The model included the fixed effects of herd-year, period of classific... ... Repository: BDPA Publication year: 2012
Genetic parameters and genetic trends of conformation and management traits in Dairy Gir cattle. The objective of this study was to estimate genetic parameters and genetic trends of different conformation and management traits regularly measured within the context of the National Dairy Gir Breedi... ...

Descriptive study and non-genetic effects on production traits of Nellore breed in the Amazon. The study and determination of the importance of non-genetic factors on production traits of the Nellore breed are essential to genetic evaluation programs, because they define which traits should or... ...

Genetic parameters for linear type traits and milk, fat, and protein production in holstein cows in Brazil. The objective of this study was to estimate genetic and phenotypic parameters for linear type traits, as well as milk yield (MY), fat yield (FY) and protein yield (PY) in 18,831 Holstein cows reared i... ...

Genetic divergence between genotypes of forage peanut in relation to agronomic and chemical traits. The objective of this study was to evaluate the genetic divergence of forage peanut in relation to agronomic and chemical traits in both rainy and dry seasons. This experiment was conducted with genot... ... Repository: BDPA Publication year: 2012
