Egg shape changes at the theropod–bird transition, and a morphometric study of amniote eggs [PDF]
, 2014 The eggs of amniotes exhibit a remarkable variety of shapes, from spherical to elongate and from symmetrical to asymmetrical. We examine eggshell geometry in a diverse sample of fossil and living amniotes using geometric morphometrics and linear ...

Effect of grass–clover forage and whole-wheat feeding on the sensory quality of eggs [PDF]
, 2010 BACKGROUND: A sensory panel evaluated the sensory profile of eggs from hens from three experimental systems: (1) an indoor system × normal layer diet (InL), (2) a grass–clover forage system × normal layer diet (GrL), and (3) a grass–clover forage system

Egg Shape I. Albumen Influence
Poultry Science, 1945 Abstract AT THE conclusion of egg shape inheritance studies reported by Marble (1943) there were available Barred Plymouth Rock hens from selected family lines that laid eggs having a wide spread in egg shape index. This population was used for a study of the physical and physiological factors influencing egg shape.

Role of carbon dioxide and ion transport in the formation of sub-embryonic fluid by the blastoderm of the Japanese quail [PDF]
, 2002 1. The explanted blastoderm of the Japanese quail was used to explore the role of ions and carbon dioxide in determining the rate of sub-embryonic fluid (SEF) production between 54 and 72 h of incubation. 2.

Egg Weight May Influence Albumen Height
Poultry Science, 1963 Abstract Albumen height should be greater in larger eggs, if all parts of the egg increase proportionally. If albumen height does change with changes in egg weight, it would be necessary to compare albumen heights at a constant egg weight. Eisen and Bohren (1963) and Eisen, Bohren and McKean (1962) have shown that a simple linear regression is ...

EGG ALBUMEN QUALITY AS AFFECTED BY BIRD ORIGIN [PDF]
Journal of Central European Agriculture, 2010 The purpose of study was to assess the effect of bird genome on egg albumen quality. Egg albumen harvested from seven local strains of laying hens: S-55, K-44, K-66, A-88, A-22, M-55 and V-44 were taken as experimental material.

Studies on carbon-13 turnover in eggs and blood of commercial layers
Brazilian Journal of Poultry Science, 2006 This paper aimed at evaluating the influence of diets containing different isotopic values of carbon-13 turnover on the half-life of egg (yolk + albumen), yolk and albumen individually, and blood of poultry using delta‰13C isotopic variation.
