Effect of storage temperature on egg quality traits in table eggs
AIP Conference Proceedings, 2016 The aim of this study was to establish the effects of storage temperature on some egg quality in table eggs during 28 days. A total of 100 fresh eggs were obtained from laying hens (Nick chick) that were raised on a local commercial farm. All eggs were collected over a 24 h period. A total of 100 eggs randomly divided into 2 treatments (5 °C and 22 °C;

Influence of selection for egg production on egg quality traits in Japanese quail
South African Journal of Animal Science, 2021 The current study investigated the influence of selection for increased egg production on external and internal egg quality traits over five generations in Japanese quail. A total of 4325 fresh eggs from 1326 females were collected each week during the egg-laying period to estimate heritability, genetic and phenotypic correlations, and correlated ...
