Prospecting major genes in dairy buffaloes
(BMC Genomics, 2015-10-28) [Artigo]
Asian buffaloes (Bubalus bubalis) have an important socio-economic role. The majority of the population is situated in developing countries. Due to the scarce resources in these countries, very few species-specific ...
Meat and carcass traits of the red-winged tinamou (Rhynchotus rufescens)
(Revista Brasileira de Ciência Avícola, 2013-07-30) [Artigo]
Tinamou (Rhynchotus rufescens) is a native bird of the Brazilian fauna and has great potential to become a domesticated species. From this perspective, the objective of this study was to evaluate the carcass and main parts ...
Association of ADIPOQ, OLR1 and PPARGC1A gene polymorphisms with growth and carcass traits in Nelore cattle
(Meta Gene, 2015) [Artigo]
In beef cattle farming, growth and carcass traits are important for genetic breeding programs. Molecular markers can be used to assist selection and increase genetic gain. The ADIPOQ, OLR1 and PPARGC1A genes are involved ...
Estudio de efectos ambientales y genéticos que influyen en la producción de leche y duración de lactación en bovinos de raza guzerat
(Livestock Research for Rural Development, 2011-07-01) [Artigo]
Objective of present work was study a influence of environmental and genetic effects over characteristics of milk total production (PL) and lactation duration (DL), from 2572 lactations of 477 Guzerat cows, collected since ...
Avaliação dos desempenhos produtivo e reprodutivo de um rebanho bubalino no Estado do Ceará
(Revista Brasileira de Zootecnia, 2001-04-01) [Artigo]
Foram avaliados os desempenhos produtivo e reprodutivo de um rebanho bubalino, localizado no município de Paracuru, litoral oeste do Estado do Ceará. Os animais foram mantidos em sistema intensivo e submetidos a duas ...
Estimation models of variance components for farrowing interval in swine
(Brazilian Archives of Biology and Technology, 2009-02-01) [Artigo]
Este trabalho teve como objetivo principal avaliar a importância da inclusão dos efeitos genético materno, comum de leitegada e de ambiente permanente no modelo de estimação de componentes de variância para a característica ...
Amh Polymorphisms and their association with traits indicative of sexual precocity in nelore heifers
(Semina:Ciencias Agrarias, 2019-07-01) [Artigo]
Anti-Müllerian Hormone (AMH) is a protein expressed in the gonads and related to ovarian follicular development. The aim of this study was to investigate the presence of polymorphisms in the AMH gene in a Nelore herd to ...
Random regressions models to describe the genetic variation of milk yield over multiple parities in Buffaloes
(Italian Journal of Animal Science, 2007-01-01) [Artigo]
The objectives of this study were to estimate (co)variance functions for additive genetic and permanent environmental effects, as well as the genetic parameters for milk yield over multiple parities, using random regressions ...
Heterogeneidade de variâncias na avaliação genética de búfalas no Brasil
(Revista Brasileira de Zootecnia, 2010-07-01) [Artigo]
Registros de produção de leite de 754 búfalas da raça Murrah foram utilizados com o objetivo de avaliar o efeito da heterogeneidade de variâncias na avaliação genética. Os componentes de covariância foram estimados pelo ...
Random regression models to estimate genetic parameters for weights in Murrah buffaloes
(Animal Science Journal, 2017-08-01) [Artigo]
This article reports genetic analysis of the weight at different ages of Murrah water buffaloes, using random regression models (RRM). Models ranging from third to sixth order polynomial were used to describe direct genetic ...
