A multivariate model was developed and used to estimate genetic parameters of body
weight (BW) at 1–6 weeks of age of broilers raised in a commercial environment. The …

Background The increase in accuracy of prediction by using genomic information has been
well-documented. However, benefits of the use of genomic information and methodology for …

The aim of this study was to estimate genetic parameters of early growth performances and
humoral immune responses (antibody titers against sheep red blood cells (SRBC) and …

Early growth traits in quails are considered as the growth performances before the inflection
point which are genetically different from body weights (BW) at later stages. Moreover, in …

ABSTRACT A major part of the growth performance in birds is the result of the combined
effects of genes, including the general and specific combining ability that requires the design …

Carcass yield of meat-type quails is strongly correlated with the weight of the birds at
slaughter (slaughter weight [SW]; body weight at 45 D of age). Moreover, prediction of …

A total of 11 826 records from 2489 quails, hatched between 2012 and 2013, were used to
estimate genetic parameters for BW (body weight) of Japanese quail using random …

Objective This study was conducted to estimate the genetic parameters and breeding values
of breast meat related traits of Pekin ducks. Selection response was also determined by …

Objectives of the current study were to i) investigate effects of selection for bodyweight at
four weeks old on bodyweight (BW) and bodyweight gain (BWG) across four generations; ii) …

We estimated genetic correlations between partial and total body weight gain (BWG) and
individual feed conversion (FC) aiming to identify possible partial traits as selection criteria …
