AbstractFull Text

The objective of this work was to study "days for a specific weight" traits in Nelore breeding programs comparing them with traditional traits such as average daily weight gain. Thus, this study aimed to estimate genetic parameters for days to reach 180 kg (D180), days to reach 300 kg (D300),...

AbstractFull Text

The aims of this study were to estimate genetics parameters for average daily gain from birth to weaning (DGBW) and post weaning average daily weight gain (PDWG) of animals of the Nellore breed, born from 1978 to 2007. Data was provided by File zootechni cal covenant ABCZ/EMBRAPA/MAPA. The dataset...

Abstract

Three different models including or not the direct and maternal non-additive effects and the fixed effects of contemporary group, parity order, direct and maternal heterosis and the direct and maternal additive genetic random effects were compared for predicting breeding values of pre-weaning daily ...

Abstract

The objective of this study was to estimate (co)variance components and genetic parameters such as heritabilities and correlations and genetic and phenotypic trends for birth weight (PN), weaning weight (PD) and 205-day adjusted liveweight gain (GNDA) in Devon cattle in Brazil. A total of 23 369...

Abstract

The aim of this study was to investigate the influence of the covariance between maternal and direct effects on the estimates of genetic parameters and on the predictions of breeding values for days to gain 160 kg in the preweaning period (D160). The analysis were carried out using the MTDFREML...

Abstract

Birthweight (BW) and pre-weaning average daily gain records of Caracu cattle (numbering to 4212 and 3844 records, respectively) were studied to evaluate the effect of cytoplasmic lineage on these parameters. The cytoplasmic lineage of each cow was traced back to the first female ancestor in the...
