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

A total of 4627 records on preweaning growth traits, birth weight (BW), weaning weight (WW) and preweaning daily gain (ADG) of Hanwoo's born form 1970 to 2005 were collected from Hanwoo Experiment Station, National Livestock Research Institute. Variance components and heritabilities of BW, WW and...

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

Variance components were estimated using data from Brahman (4497 calves from 266 sires and 1311 dams) cattle at ANSA Genetics, Philippines. The traits were birth weight (BW), preweaning average daily gain (PRADG), preweaning gain (PRGAIN), and adjusted 210-day weaning weight (ADWW). The phenotypic...

Abstract

The aim of this study was to evaluate selection criteria in Gyr [Gir] cattle based on the traits such as average daily gain from birth to weaning (ADG) and number of days to gain 160 kg from birth to weaning (D160). Data from the Brazilian Association of Zebu Breeders of 16 592 calves, 507 sires,...

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...
