Associations between reproductive and carcass traits in Nellore. Objetivou-se com este trabalho estimar os parâmetros genéticos e os componentes de (co)variância para as características de carcaça: peso (PESO), área de olho de lombo (AOL), espessura de gordura subc... ...

Candidate genes for male and female reproductive traits in Canchim beef cattle. Background: Beef cattle breeding programs in Brazil have placed greater emphasis on the genomic study of reproductive traits of males and females due to their economic importance. In this study, genom... ... Repository: BDPA Publication year: 2017
Estimates of genetic parameters for carcass and reproductive traits in Nelore cattle. The search for a more efficient beef cattle production system has led to the use of considerable number of traits as selection criteria. As such, the success of breeding programs relies on accurate es... ... Repository: BDPA Publication year: 2018
Genetic analysis of productive and reproductive traits in multiple-breed dairy cattle populations. The objective of this work was to determine whether the random regression model using linear splines (RRMLS) is suitable to estimate the genetic parameters for productive and reproductive traits of a... ...

Candidate genes for disease, reproduction and meat quality traits in Portuguese native breeds. Native Portuguese cattle breeds are a ?biodiversity deposit? resulting from genetic and environmental effects accumulated over the years. We assessed two cattle breeds representative of Portuguese nat... ... Repository: BDPA Publication year: 2022
Ultrasonographic evaluation of reproductive tract measures and fat thickness traits in pre-pubertal nellore heifers. The aim of this study was to evaluate the relationship between reproductive tract and fat thickness measures obtained by ultrasound in prepubertal Nellore heifers. A total of 128 Nellore heifers born... ... Repository: BDPA Publication year: 2012
Association of polymorphisms in the IGF1, GH and PIT1 genes with growth and reproductive traits in Canchim cattle. A variance component approach for quantitative trait loci (QTL) mapping was proposed by George et al. (2000), which assumes a mixed inheritance model (polygenes and QTL effects). This approach allows... ... Repository: BDPA Publication year: 2010
Genetic correlations between visual slaughter conformation scores and growth and reproductive traits in Canchim cattle. We obtained heritability and (co)variance component estimates for slaughter conformation scores at 420 days of age (SCS420), age at calving (first, AFC; second, ASC), calving occurrence until 38 month... ...

Can reproductive traits contribute to the success of ecological restoration? Direct sowing has been proposed as an alternative to planting seedlings because of its low cost. However, there are still few works with direct seeding that aim to select species that best respond to... ... Repository: BDPA Publication year: 2017
Genetic parameters reproductive traits in a strain if laying hens. Repository: BDPA Publication year: 2014
