The aim of this study was to evaluate the relationship between slaughter age and slaughter-
carcass characteristics in 2 quail lines. With this aim, a Japanese quail flock subjected to …

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 …

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 …

Improving resistance against disease is important in the animal and poultry industry.
Besides drugs and vaccines, genetic selection for improved immune systems may be an …

The present study estimates additive and non-additive effects on egg production traits in
genotypes generated through pure mating and reciprocal crossing of Fayoumi (FM) with …

A better understanding of genetic parameters is required to evaluate the combining abilities
of different genotypes. The current experiment aimed to estimate crossbreeding parameters …

Qingyuan partridge chicken is an important indigenous chicken in China. In its breeding
schemes, chickens are usually selected at the age of 105‐day‐old for five traits, including …

This study investigated the hypothesis that methionine supplementation of Japanese quail
(Coturnix coturnix japonica) hens can reduce the effects of oxidative stress and improve the …

Aim of study: To select the appropriate model for body weight gain (BWG) traits in different
ages and estimation of additive and non-additive genetic variances based on the best …
